An announceo special inspection on March 1 and 29, 1938 of an area formerly enned by Bendix Corporation in Teterboro, New Jersey, on j

which drums and soil containing radioactive material were discovered.

Areas Inspected:

Samples of material from the drums and soil were taken for analysis in tne NRC Region I Labcratory.

Past licensed activities with regard to radicactive material were reviewed with the representatives of Bendix and the current owners of the properties, MetPath, Inc. and Sumitoma Machinery Corporation.

_Re sul ts :

Approximately 15-20 drums containing radioactive material are visible 3

along a 100-foot stretch of a drainage ditch bank belonging to MetPath, Inc.

Radiation levels range from 4 microroentgens (microR) per hour (background) at the fenceline, up to 800 microrcentgens per hour near some drums.

Analysis of samples indicate normal concentrations of thorium daughters in the soil, and higher concentrations of thorium in the samples taken from drums.

Radiation levels along the drainage ditch through the Sumitoma property range from 4 microroentgens per hour, to 30 microreentgens per hour in two areas along the l

ditch where sediment has accumulated.

Analysis of samples from these areas indicate levels of thorium slightly higher than normal.

In addition, isolated spots of soil had radiation levels up to 3000 microrcentgens per hour.

Samples taken from these areas show no thorium contamination, but elevated levels of radium-226.

Quantities of thorium requiring an NRC license exist on the MetPath, Inc property without a valid NRC license.

Background===

i Allied Signal is the parent company of Allied Signal Aerospace - Bendix Division (Allied Bendix Aerospace or Bendix), located in Teterboro, New Jersey. Bendix is now involved in the research and development, engineering, and manufacture of flight systems and test equipnent for the systems.

They currently hold NRC License No. 29-15797-01 which authorizes the pos-session of a Lixiscope containing iodine-125.

They also lease a large l

number of generally-licensed 3M polonium-210 static eliminators. A license to possess source material was first issued to Eclipse-Pioneer Division of Bendix Aviation Corporation by the Atomic Energy Commission (AEC) in 1958.

It authorized possession and use of 4% thorium-magnesium alloy. Subsequent licenses issued to Bendix pemitted use of up to 10,000 pounds of 40%

thorium magnesium hardener at a site in Teterboro. The most recent source 3

material license expired in 1973, although other records indicate a thorium license may have been active as late as 1975.

In January,1988, during a survey of the Teterboro, New Jersey area, the Department of Energy (DOE) identified several drums of radioactive material along the outside of the fenceline of property belonging to MetPath Inc.

(MetPath). According to the legal counsel for MetPath, this property was purchased from Bendix. DOE analysis indicated that the drums contain natural thorium. Radioactive material was also identified on an adjacent property now owned by Sumitoma Machinery Corporation (Sumitoma) which had i

also been purchased from Bendix.

The DOE survey reports are included as to this report.

Property History Personnel interviewed stated that Bendix acquired the the 101-acre Teterboro property in 1937.

This original Bendix property is now approximately bounded on the east by Teterboro Airport, on the north by Route 46, on the west by Route 17, and on the south by Malcolm Avenue. When purchased, the land was undeveloped, consisting mainly of marsh and swampland. Approximately three to four feet of fill was added prior to building on the property.

Zero to five feet of additional fill was used in the mid-1970's to raise the property level to ten feet above sea level, in accordance with Bergen County flood control specifications.

In 1941, Bendix sold a large portion of this property to the Navy, which built a foundry for the production of magnesium-thorium alloy.

The foundry was operated by Bendix under contract to the Navy. The Navy site included a sewage treatment facility, a small incinerator, and sand pits for treat-ment of magnesium-thorium waste chips from the Bendix machine shops.

In 1954, an addition to the foundry was built for the production of aluminum castings. Bendix processed items cast in the foundry in machine shops on their adjacent property.

The Navy tenninated its use of the foundry in 1961.

Bendix re-purchased the property from the Navy in 1961 and continued to operate the foundry until 1964 Machinery from the foundry was later sold to other foundries which continued to produce the castings needed by Bendix.

In 1968, the foundry building was closed and cleaned out.

The buildings were converted for use as office space in 1969.

Representatives of Bendix stated that thirty acres of land south of the i

foundry (adjacent to Malcolm Avenue) were sold, part to MetPath and part i

to Sumitoma, in the late 1970's.

Representatives of HetPath stated they purchased their property on September 29, 1980.

Sumitoma purchased the soutSwest corner of the Bendix property, which contained the sewage facility, incinerator, and sand pits.

Representatives of Sumitoma stated that the only structures on this property at the time of purchase were a concrete sewage tank and some small concrete structures that may have been supports or foundations.

211 was removed from the center portion of the property, and replaced with soil from the Franklin Lakes area of New Jersey in order to provide an adequate foundation for subsequent con-struction of the current building, an office and warehouse of about 75,000 square feet. No other changes were made. According to the Sumitona representatives, MetPath hired the same contractor who used the same procedures to construct an office and laboratory building on its property.

4 4.

Use of Thorium Use of thorium at the Teterboro site may have begun in the Navy foundry as early as 1941.

Furty percent thorium alloy was received at the foundry in the fonn of small metal pellets and added to magnesium to produce standard magnestua-thorium alloys, most commonly containing 3.3% thorium.

Represen-tatives of Bendix stated that analytical records indicate no thorium use at the foundry after 1951. However, AEC licenses were issued to Bendix Corporation in Teterboro, New Jersey during the period 1958 to 1973 for possession of up to 10,000 pounds of 40', thorium-magnesium hardner for production of up to 4% thorium-magnesium alloy.

According to Bendix representatives, waste scraps of the final alloy from the foundry were recycled.

There are no records available pertaining to the disposal of slag or other waste material from the foundry.

The magnesium-thorium allos from the foundry was machined into final products by Bendix in their facility adjacent to the foundry. Waste chips of the alloy were at one tire disposed by incineration in a small (4 feet by 4 feet by 6 feet) brick incinerator primarily esed for burning documents.

In 1961, the licensee was cited by the AEC for violations related to the incineration of waste.

Bendix representatives stated that the waste chips were then placed in sand beds, chemically treated for 20-30 days, then disposed to a landfill. During a 1981 NRC inspection, Bendix representatives stated that weste had beer transferred to a firr licer. sed by tre AEC for this retu i61.

(See Report No. 99990001/81-15).

ho records of waste disresel ty En dix during this time are available.

5.

Instrumentation used and Sarple Analysis Radiation levels were measured using a Ludlum Model 12S Micro R Meter, Serial Nurter NRC 008580, calibrated December 4,1987.

Background levels measured with this instrument are 4-6 microR/ hour. Samples of the contents of the drums and of toil taken from areas adjacent to the drums were counted at the Region I Laboratory using an intrinsic gerinani"m detector and a multichannel analyzer. Soil samples were taken from 100 cmr areas at depths of 5-10 cm. Thorium and radium concentrations in the samples were detennined using activities of selected radioactive decay products. A description of the samples is in Attachment 2.

The lower limit of detection (LLD) is 0.355 picoeuries of thorium per gram of soil and 0.349 picoeuries of radium-226 per gram of soil.

16.

Inspector Observations The 55-gallon drums identified by DOE are located on the outside of the west fence of the MetPath property (parallel to Route 17). Although the drums are outside of the enclosure, access to them is most easily attained

,by crossing the Bendix property, through the security fences.

Drums are visible beginning about eighty feet south of the Bendix property, along the bank of a drainage ditch. The drainage ditch feeds into the Berry Creek, which flows into the Hackensack River.

4 5

The drainage ditch passes through the western edge of all three properties (Bendix, MetPath, Sumitoma) in Teterboro, parallel to Route 17. The bank is about eight feet wide along the MetPath property where an old, now unused, parking lot is located. Along the Sumitoma property the bank drops sharply to the level of the ditch.

The ditch is about six feet below the property level, and about eight feet wide.

On the first day of the inspection, the water depth was approximately six inches. The drums identified as containing radioactive material are located along a one hundred foot section of the bank of the drainage ditch on the MetPath property, adjacent to the old parking lot.

Approximately 15-20 drums are visible.

These drums have deteriorated, exposing the contenb The contents of some drums appear to be concrete-like.

In other ie material is wet and crumbly and ranges from white te dark gn..

alor.

Drums appear to be lying on their sides, perpendicular to ti._ fence line.

Drums are visible at the top of the bank near the fence as well as at the water line.

7.

Radiation level Surveys Radiation levels along the inside of the MetPath fenceline were all the same as background. Radiation levels along the outside of the fence at ground level were also background, except near fenceposts 8, 9, and 10 where drums were exposed.

Radiation levels near these drums were 40-60 microR/ hour.

Radiation levels near the ground at the waterline ranged from 4-12 microR/ hour except in areas where drums ere exposed. Radiation levels at approximately one meter above the surface of the 1round it the water line ranged from 4 to 80 microR/ hour. The contents of drums found along the water line had radiation levels ranging from 40 to 800 microR/ hour at conhet. A complete description of the survey of this section of the d0 S is included as Attachment 3.

No other portion of the MetPath I m erty was surveyed.

A survey of the Sumitoma property identified a 25-foot-by-30-foot area in the northeast corner with radiation levels generally ranging from 14-100 microR/ hour.

One spot with a level of 2000 microR/ hour was identified in this area.

In addition, several discrete spots were noted on the west and south sides of the Sumitoma building with levels of 20-30 microR/hr. One spot less than two inches in diameter had a level of 3000 microR/ hour.

This was located approximately 15 feet west of the building and 20 feet north of the ornamental garden fence. Surveys along the drainage ditch identified two areas with radiation levels of 20-30 microR/ hour wher; debris and sediment had collected along the bank.

All other areas wery background.

Surveys were also conducted inside the 75000-square feet office / warehouse building on the Sum ltoma property.

No radiation levels above bach;round were identified.

6 8.

Contamination Surveys Samples taken from four drums on the MetPath property were found to contain as much as 480 picocuries of thorium per gram of sample (pCi/g).

Soil samples taken from the ditch along the MetPath and Sumitoma prop-erties had thorium levels of 0.7 - 25.4 pC1/g. Nonnal environmental concentrations of thorium in soil typically fall in the range of 0.2 - 1.3 pCi/g.

10 CFR 40.13(a) exempts from NRC licensing material that is less than 0.05% by weight source material, which is equivalent to 54.5 pico-curies per gram of thorium.

The data in Attechment 2 indicates that the material in two of the four drums sampled exceed the concentration of thorium which is exempted from licensing.

The two soil samples taken from other areas of the Sumitoma property indicated radium-226 contamination. No thorium was noted in these samples.

The sample west of the building centeining 315 114 pCi/g, and the sample taken from the northeast corner contained 2500 109 pCi/g.

Environmental concentrations of radium-226 in soil typically fall in the range of 0.5 -

2.0 pCi/g. This material is regulated by the State of New Jersey.

The possession of the quantities of thorium determined in samples from the drums without a valid NRC licente is an apparent violation of 10 CFR Part 40.

9.

Interviews With Personnei Few records exist of activities on this site during use of the foundry.

Most information was received from persons who worked for Bendix during that time. None of the representatives contacted had any knowledge of the drums prior to their discovery by 00E.

None of the Bendix representatives could identify the drums, their contents, or the time of their placement along the ditch.

It was suggested by Bendix representatives that the barrels may have been used as support for the bank, since the adjacent area had been used as a parking lot for the foundry.

Representatives of MetPath, Inc. had no knowledge of the existence of the drums prior to their discovery by D0E.

Representatives of MetPath verified that the ditch is part of their property, although it is outside of the fenceline.

Representatives of Sumitoma had no information on the use of radioactive material on their property prior to 1976.

They were unaware of any radioactive contamination of their property until the DOE survey.

10.

Exit Interview The inspectors met with the persons identified in Paragraph 1 to discuss the scope and findings of the inspection.

Backoround The Bendix Corporation was licensed to produce magnesium therium alloys between 1958 and 1975.

Thorium alloy containing 40% thorium was added to magnesium castings to produce final castings of alloy containing up to 3%

a thorium.

The purpose of this inspection was to conduct an independent radiation survey of the physical facilities used while the license was in effect.

3.

Interviews with Personnel Company representatives stated that the building which contained the foundry where thorium was used was converted into office space in 1969.

Photographs taken during the cleanup of this area demonstrated the thorough and extensive cleaning which was required.

This cleaning would have thoroughly decontaminated the foundary had there been any residual thorium' contamination.

In 1961, the licensee was cited by the AEC for violations related to incineration of waste from this process in a remote field' area.

Bendix representatives state that subsequently, waste was transferred to a firm licensed by the AEC for this material.

Bendix representatives also stated that in the mid-70's, this remote field area was scraped clean and fille 3 in with up to ten feet of clean fill.

4.

Independent Measurements The inspector surveyed the former furnace area and the area formerly used fer storage of thorium alloys, using a Ludlum Model 12S Micro R meter.

Average radiation levels were 0.010-0.015 mR/hr which is 'n the range of natural background.

Smear surveys taken in these areas indicated no removable contamination above background.

l MAR 1 1988 Mr. William Hooper Manager of Plant Engineering Allied Bendix Aerospace Corporation Route 46 and Industrial Avenue Teterboro, New Jercey 07608

Dear Mr. Hooper:

Asyouareaware,theDepartmentofinergy(DOE)isconductingaresearch and development project to decontaminate the former Maywood Chemical Canpany site in Haywood, New Jersey, and associated vicinity properties.

This effort includes surveys conducted by DOE in order to identify vicinity properties associated with the Haywood site. As a result of a wide-area scan (mobile gama scan) conducted near your facility, some radiation anomalies were identified on your property in Teterboro and two neighboring properties owned by Sumitomo Machinery Corporation and Metpath Incorporated. Radiological surveys were conducted between November 1986 and January 1988 to identify the source of these anomalies and determine if they were connected with the fomer Maywood Chemical Company Operations.

The residual radioactivity identified on your property by the survey was primarily due to elevated levels of thorium and radium and their associated decay products in the soil. The infomation collected as a result of these activities indicates that the residual radioactive material was not derived from the Maywood site. Therefore, your site will not be included in the DOE Maywood project.

It appears the thorium contamination identified on your property may be related to some past activities licensed by the Atomic Energy Comission (as a predecessor to the Nuclear Regulatory Comission), which were conducted for the Navy at a plant operated and later owned by Bendix. The source of the radium contamination is not known; however, it is similar to the type of residues we have seen that are related to radium-coated instruments, such as airplane gauges and watch dials.

As a result of these findings, we are notifying (by copy of this letter) the Nuclear Regulatory Comission, and the State of New Jersey, of our findings, as they have regulatory authority over the thorium and radium, respectively. I am also providing a copy of the letter to the Department of Defense because the thorium contamination may be related to the former Navy plant.

/

A draft preliminary sumary of the survey results is enclosed for your information. A survey report documenting the results of the survey will te provided to you in the next few months. As the results indicate, a portion

~

\\

l 2

l of your property may contain residual radioactive material above guidelines used by DOE to determine if a property needs remedial action; however, as noted above, these guidelines do not apply to your property.

Based on the measurements taken and the location of the contamination on your property, it does not appear that there is significant potential for workers at your 1

facility to be exposed to radiation levels in excess of dose guidelines.

However, until further evaluation is completed by you or other organizations, as appropriate, we recomend you do not allow individuals to be exposed in these areas over extended periods. Because most of the areas of concern (i.e., two spots in the outfield of your ball park and several around the buildings and parking lot to the southwest of your Main Building) are less than 1 square meter in size, chances of exposures to workers exceeding applicable dose guidelines are small.

It is noted that the external gama rate measurements provided in the sumary are at contact with the surface and are significantly lower at the point of exposure (1 meter from the surface). There are~also some drums containing thorium-rich compounds near the drainage ditch, near property which you are leasing from Metpath Incorporated. This area is presently fenced; however, the drums are in poor condition and are releasing material to the environment.

Concentrations of thorium in the drums exceeded 1000 pC1/ gram of thorium.

While we have not identified any imediate hazard to the public or your workers associated with these drums, access to the area should be minimized at least until some additional evaluations are completed by the appropriate organizations and/or some interim steps to prevent migration of the material from the site is taken. The Nuclear Regulatory Comission should be contacted with regard to any actions associated with the thorium.

If you have any questions regarding this survey or the infortnation provided, please contact Mr. Andrew Wallo of my staff.

Sincerely,

\\

a up Survey Results Guidelines applicable to FUSRAP projects are sumarized in Table 1 (ref.

3). The nonnal background radiation levels for the northern New Jersey area are presented in Table 2.

These data are provided for comparison with results presented in this section. All direct measurement results presented in this report are gross readings; background radiation levels have not been subtracted. Similarly, bac(ground concentrations have not been subtracted from radionuclide concentrations measured in environmental samples.

Surface Cama Radiation Lavels Camma radiation levels measured during a gamma scan of the surface Gamma of the property at each sample location are shown in Fig. 2.

exposure rates over the vast portion of the property ranged from 7 to 13 pR/h. However, there were two locations in the ball field and 7 ea d Locations near the northern corner of the main parking lot with bevated readings. One of these small areas was outside the security fence in the parking lot, and the others were inside the plant area near the corner of the lot (Fig. 2).

Soil samples were taken from these two areas and labeled TJ02B3 and TJ02B4. The two small spots located in the ball field vere sampled and labeled TJ02B1 and TJ02B2. All of the elevated "spots" were less than one meter square and had scan ranges from just above background (Table 2) up to 200,000 pR/h.

Systematic and Biased Soil Samples Systematic and biased soil samples were taken from various loca-tions on the property for radionuclide analyses. locations of the sys-tematic (TJ025) and biased (TJ02B) samples are shown in Fig. 3, with results of laboratory analyses provided in Table 3.

Concentrations of radium, thorium, and uranium in these samples ranged from 0.46-2700 pCi/g, 0.34-5.7 pCi/g, and 0.39 2.0 pCi/g, respectively. Samples having the greatest concentrations of radium and thorium were TJ02B1, TJ0252, TJ02B3, TJ0254, and TJ02B6, each with values for radium in excess of DOE criteria (Table 1).

Samples TJ02B1A&B, TJ0253C, and TJ02B4B vere not processed, because they exceeded the counting capacity of standard environmental analytical equipment and clearly exceeded the DOE guidelines.

Dear Mr. Menard:

Asyouareaware,theDepartmentofEnergy(DOE)isconductingaresearch and development project to decontaminate the former Maywood Chemical Company site in Maywood, New Jersey,.and associated vicinity properties.

This effort includes surveys conducted by DOE in order to identify vicinity properties associated with the Maywood site. As a result of a wide-area j

scan (mobile gama scan) conducted near your facility, some radiation anomalies were identified on your property in Teterboro and two neighboring properties owned by Sumitomo Machinery Corporation and Allied Bendix 4

At:rospace Corporation.

Radiologicel surveys were conducted between.

November 1986 and January 1988 to identify the source of these anomalies i

i and deterdne if they were connected with the fomer Maywood Chemical Company Operations.

The residual radioactivity identified on your property by the survey was primarily due to elevated levels of thorium and radium and their associated decay products in the soil. The infonnation collected as a result of these activities indicates that the residual radioactive material was not derived from the Maywood site. Therafore, your site will not be included in the DOE Maywood project.

It appears the thorium contamination identified on your property may be related to some past activities licensed by the Atomic Energy Commission (as a predecessor to the Nuclear Regulatory Comission), which were conducted for the Navy at a plant operated and later owned by Bendix. The source of the radium contamination is not known; however, it is similar to the type of ~ residues we have seen that are related to radium-coated instruments, such as airplane gauges and watch dials.

As a result of these findings, we are notifying (by copy of this letter) the Nuclear Regulatory Comission, and the State of New Jersey of our findings es they have regulatory authority over the thorium and radium, respectively.

I am also providing a copy of the letter to the Department of Defense because the thorium contamination may be related to the fonner Navy plant.

A draft preliminary sumary of the survey results is enclosed for your

/

infonnation. Note, the gama exposure rate measurements provided with this data are contact measurements. Levels at the point of exposure, 1 meter.

1 2

will probably be lower. A survey report documenting the results of the survey will be provided to you in the next few months. As the results indicate, a portion of your property may contain residual material above guidelines used by DOE to determine if a property needs remedial action; wwever, as noted above, these guidelines do not apply to your property.

Based on the measurements taken and the location of the contamination on your property, it does not appear that your workers are being exposed to radiation levels in excess of dose guidelines. As a result, the contamination does not appear to represent an imediate hazard to workers.

However, until further evaluation is completed by you or other organizations, as appropriate, we recomend you minimize use of the contaminated areas, particularly the area near the drainage ditch in the ncrtheast corner of your property. This area is presently fenced; however, there are several exposed drums containing thorium rich compounds at this location. The drums are in poor condition and are releasing material to the environment. Concentrations of thorium in the drums exceeded 1000 pCi/ gram of thorium. We have com>1eted a spectrochemical analysis of the contents of the drum, which will se provided with the surve., tapart. While we have not identified any imediate hazard to the p4blic or your workers associated with these drums, you may wish to take some interim steps to prevent migration of the material from the site. The Nuclear Regulatory Comission should be contacted with regard to any actions associated with the thorium.

If you have any questions regarding this survey or the information provided, please contact Mr. Andrew Wallo of my staff.

Sincerely, f.

presented in this report are gross readings; background radiation levels have not been subtracted. Similarly, bactground concentrations have not been subtracted from radionuclide concentrations measured in environmental samples.

Surface Cama Radiation IAvels Camma radiation levels measured;at each sample location are shown in Fig. 2.

Camma exposure rates'over the major portion _ of the property ranged from 9 to 18 pR/h, with a maximum of 28 pR/h in two areas of less j

than 0.1 m2 each. The highest measurements were in the northern corner of the property. Most gamma readings were near normal background for the northern New Jersey area (Table 2).

Some slightly elevated gamma levels were detected in certain areas of the parking lot. Thase elvva-ted measurements originated from a particular type of asphalt used in both paving and patching various sections of the parking lot. This type of asphalt has been used in other locations in the Maywood area, where it was also found to have elevated gamma levels. Based on asphalt sam-1 pling of a property in one of these other areas, the fill aggregate is thought to contain slightly elevated, naturally occuring radionuclides.

Systematic Soil Samples Systematic soil samples were taken from various locations on the property for radionuelide analyses.

Locations of these samples (TJ03S) are shown in Fig. 3, with results of laboratory analyses provided in Table 3.

Concentrations of radium, thorium, and uranium in these sam-pies ranged from 0.33-77 pei/g, 0.39 31 pCi/g, and 0.38-1.0 pCi/g, respectively. Areas of greatest concentrations for radium and thorium were in samples TJ03S8 and TJ03S9, with values of 28-77 pCi/g for radium in TJ0358 and 12-31 pCi/g for thorium in TJ03S9, both in excess of DOE criteria (Table 1). All readings for uranium were near or below natural background levels for the area (Table 2).

Department of Energy Washington, DC 20545 MAR 1 1988 Mr. William M. Lechler Executive Vice President Sumitomo Machinery Corporation 7 Malcolm Avenue Teterboro, New Jersey 07608 i

Dear Mr. Lechler:

As you are aware, the Department of Energy (DOE) is conducting a research and development program to decontaminate the fomer Maywood Cnemical Company site in Maywood, New Jersey, and associated vicinity propertier..

This effort includen surveys conducted by DOE in order to identify vicinity propertiep associated with the Maywood site. As a result of a wide area scan (mobile gama scan) conducted near your facility, some radiation anomalies were identified on your property in Teterboro and two neighboring properties owned by Metpath Incorporated and Allied Bendix Aerospace Corporation.

Radiological surveys were conducted between November 1986 and January 1988 to identify the source of these anomalies and detemine if they were connected with the fomer Maywood Chemical Cotopany Operations.

The residual radioactivity identitioJ on your property by the survey was primarily due to elevated levels of thorium and radium and their associated decay products in the soil. The information collected as a result of these activities indicates that '-2 residual radioactive material was not derived from the Maywood site. Tb..efore, your site will not be included in the Maywood project.

It appears the thorium contamination identified on your property may be related to some past activities licensed by the Atomic Energy Comission (as a predecessor to the Nuclear Regulatory Comission), wh'ch were conducted for the Navy at a plant operated and later owned by Bendix. The source of the radium contamination is not known; however, it is similar to the type of residues we have seen that are related to radium-coated instruments. such as airplane gauges und watch dials.

As a resuli, of these firdings, we are notifying (by copy of this letter) the Nuclear Regulatory Comission, and the State of New Jersey of oc findings, as each has regulatory authority over the thorium and radium, respectively.

I am also providing a copy of the letter to the Department of Defense bect.use the thorium contamination may tse related to the former Navy plant.

/

A draft preliminary sumary of the survey results is enclosed fnr your information. A survey report documenting the results of the survey will be provided to you in the next few months. As the results indicate, a M

w

=

\\

2 significant portion of your property may be contaminated above guidelines used by DOE to determine if a property needs remedial action; however, as noted above, these guidelines do not apply tt your property. Based on the external gart: measursments taken at one meter from the ground and the locatica of the contamination on your property, it does not appear that your workers are being exposed to radiation levels in excess of guidelines.

As a result, the contamination does not appear to represent an immediate hazard to workers or the public. However, until further evaluation is completed by you or other organizations, as appropriate, we recommend you minimize use of the contaminated creas, particularly the area near the drainage ditch and the southeast corner of your property.

If you have any questions regarding this survey or the information provided, please contact Mr. Andrew Wallo of my staff.

Sincerely.

Survey Results_

y%2. 2 Guidelines applicable to FUSRAP projects are sumarized in Table 1 (ref.

3). The nomal background radiation levels for the northern New Jersey area are presented in Table 2.

These data are provided for comparison with results presented in this section. All direct measurement results j

presented in this report are gros: readings; background radiation levels i

have not been subtracted.

Similarly, background concentrations have not bean subtracted from radionuclide concentrations measured in environmental samples.

Surface Gama Radiation Levels Gama exposure rates at about 1 mete' from the surfact: are shown in Table

~

r 3A. These rates vary from 6 to 30 uR/h and, over most of the site, were in a range typical of background levels. Gama radiation levels at the ground surface, measured during a gama scan of the surface of the property, are shown in Fig. 2 and detailed in Table 3.

As with the measurements at 1 meter, gama exposure rates over the majcr portion of the property were typical of or near background and ranged from 7 to 12 uR/h.

However, gama levels on significant portions of the property read a few hundred uR/h, with two areas reading upwards of 1260 uR/h. One of these areas covered the eastern corner of the property; the other area was located on the bank of a ditch running along the western side of the building.

Both of these areas are indicated by crosshatching in Fig. 2.

Other gama readings along this bank ranged from 10-314 uR/h, with the greatest concentration of elevated readings existing between grid lines 2+00, 200L and 7+00, 300L.

The paved sections used for loading docks on the north side of the building had severai spots of elevated gama. The source was either in the asphalt or under it.

No samples were taken from this asphalt area.

SYstenAtic and Biased Soil $amples Systematic and biased soil samples were taken from various loca.

tiens on the property for radionuclide analyses. locations of the sys-tematic (TJ013) and biased (TJ013) samples are shown in Fig. 3, with results of laboratory analyses provided in Table 4.

Concentrations of radium, chorium, and uranium in the systematic samples ranged fros"-

0.66 22 pCi/g, 0.41-5.2 pci/g, and 0.36 3.6 pCi/g, respectively. Areas of greatest concentrations for radium and thorium in the systematic sam-pies were in locations TJ0156 and TJ01521; both were above DOE guide-lines (Table 1). Areas with elevated concentrations of radionuclides existed mostly along the banks of the ditch and in the eastern corner of the property. Concentrations of radium, thorium, and uranium in the biased samples ranged from 0.76 1000 pC1/g, 0.68 270 pCi/g, and 0.66 4.6 pCi/g, respactively. Areas of greatest concentrations for rtdium and thorium f.n the biased simples were again mostly in locations from.

along the banks of the ditch (TJ0lbl-3,5. 7,10 and 11) and in the eastern corner of the property (TJ01B8 and 9), except for TJ0184 on the southeastern side of the building with a concentration of 42 pCi/g for radium (Fig. 3). Most of the uranium levels were within normal back-ground levels for the northern Now Jersey area (Table 2). Concentra-tions of radium and thorium in the biased samples generally exceed the DOE guidelines for soil (Table 1). Portions of samples TJ0187 and TJ01510 were not processed because they exceeded the counting capacity of standard analytical equipment and clearly axceeded the environmental guidelines.
