l Renewal of SNM 1635 i
l O

Dear Mr. Hickey:
Stevens Institute of Technology, Hoboken, N.J., hereby makes application for a special nuclear materials license.
4 I.
Stevens institute of Technology, Hoboken, N.J. 07030, is chartered in the State of New Jersey. Offices, classrooms, and laboratories are located on the campus in Hoboken, N.J. The nrincipal officers of the Institute are:
l Kenneth C. Rogers, Ph.D., President (U.S. citizen) i Robert F. Cotellesso, Ph.D., Provost (U.S. citizen) l The individuals in charge of the special nuclear material will be:
Steven C. Sylvester, Ph.D., Radiation Safety Officer (U.S. citizen)
Milos Seidl, Ph.D.
) (U.S. citizens) Professors associated with the Timothy R. Hart, Ph.D. )
course in which SNM is used l
Control of the Institute is in the hands of the Administrative Officers who are responsive to the faculty but responsible to the Board of Trustees; all of the latter are U.S. citizens. There is no control or ownership exercised over the applicant by any olien, foreign corporation or foreign government, i
2.
The use of the SNM is in experiments in an instructional laboratory at the senior undergraduate and graduate level, under the guidance of Drs. Timothy Hart or Milos Seidl with the help of a graduate assistant assigned to the laboratory. The instructional laboro-tory is located in the Kidde building.
lhe source will be used in experiments involving the radioactive activation of silver and indium by neutrons.
3.
The source is a numec Type I sealed plutonium-beryllium neutron source manufactured a mass of 80 gm and a neutrcn flux of 8 x 10gtion. The source has an activity of 5 curi by NuclearMaterials and Equipment Corpor neutron /sec. The serial number of source is 800120.

i R;:
Mtil Centr:I I8918 R;nswil of 1635 l have contacted Mr. Gm,t La Pier of Babcock-Wilcox who infonned me that no infonnation on the expected encapsulation lifetime was aveilable. The source has been used and will only be used at room temperature and a%ospheric pressure; leak tests which have been perfonned show no signs of leaka,e.
l 4.
Infonnation sheets on Timothy R. Hart, Milos Seidl, and Steven C. Sylvester are enclosed (see attachments I, 2 and 3).
5.
The PuBe source is contained within a Neutron Beam Irradiation Facility described in a booklet supplied by Atomic Labomfories, Inc. (Catalog No. 71864, see attachment 4).
This neutron howitzer has four ports each nonnolly locked closed by a lucite plug. Th2 howitzer is 24" in diameter, 24" high and is filled with paraffin. This shielding of about 30cm corresponds to 5 half-value thicknesses for fast neutrons. At the source the fast 6
2 neutrons are emitted at a rate of 8 x 10 n/sec. Without the paraffin, the flux in n/cm _
sec at the surface of the howitzer would be:
6 8 x (10 )
n
= 710 4TT(30)2 2 _ 3,c cm With the paraffin, the flux at the surface of the container is:
I 710 x 2-5
= 22 cm' see The source is used only in the howitzer and is ' handled" by means of strings attached to the source holder. The source is nonnolly located 3" below the center line of the ports and is raised to the port height by the strings. In the event that a string should break, we would contact on outside firm which specializes in the handling of radioactive materials to j
replace the broken string. We would not attempt to do this ourselves since we are not equipped to handle the source outside the howitzer.
The howitzer is kept and used in a locked storage room under the control of Dr. Seidl.
Access to this room is by permission of Dr. Seidl, the radiation safety office, or security.
We have a Geiger counter manufactured by William B.' Johnson & Associates, Inc. -
model GSM-5 with a GP-200 probe. The probe has a 1.4 mg/cm2 window which is able to detect 5 mev alpha particles from plutonium since these alpha particles are capable of penetmting 3.4 mg/cm2. This counter is calibrated every three months using two NBS j
57 o and 60 Co. The dose rate for each individual source in mrem /hr traceable sources:
C is measured as a functior of distance from the source and compared with a calculated dose mte using the following formula:
i b^
dose rate =
r2 where f' = Gamma Radiation level of the radionuclide (from the Radiological Health Handbek revised editinn 1970).
l A
= Activity of the source.
r
= The distance fran the source to the detector.
l L
i Rt M:ll Control 18918 Ranewal of SNM 1635 6.
Radiation Protection Program A poster is located in a censpicuous place advising workers about our licenses and Nuclear Regulatory Commission regulations (see attachment 5).
The radiation safety officer is Dr. Steven C. Sylvester. His duties include:
outhorizing all purchases of radioactive material; overseeing the pick-ua of radio-octive waste; recording infonnation received on exposures incurred by o l personnel working with radioactive materials; conducting three surveys per year; consulting with radiation personnel to keep radiation doses os low as possible; and maintaining records on surveys and inventories.
All personnel working with mdioactive materials use thennoluminisent dosimeters which detect gammo and beto radiation. These are used for whole-body monitoring and are " read" by a commercial service on a quarterly basis. To date o t exposure for o person working with the neutron source is.025 rem / year. ypical Radiation surveys are perfonned by the radiation safety officer three times per year.
The GSM-5 Geiger counter is used to measure the level of gamma radiation at the surface of the neutron howitzer and at a distance of 6 feet from the howitzer.
The program using the PuBe source does not generate any radioactive waste. Waste which is generated under our Byproduct license is picked up by Teledyne isotopes, Westwood, New Jersey.
The radiation safety officer keeps a record of all personnei exposures on New Jersey State Department of Environmental Protection fonn BRP-26 (see attacheent 6). Copies of inventories and surveys are also maintained by the radiation safety officer.
The license application covers the special nuclear material we already have, we will not be ordering any additional material.
Leck tests are perfonned three times per year by Dr. Seidl. These are done with a wet swab inserted into each of the four howitzer ports with the source raised to the level of the ports. The test swobs are placed in a lead-shielded contaiger in front of a Geiger tube (Amperex Model 200CB, window thickness 1.2 mg/cm ). The resulting countrate is compared against nonnal background. To date no test sample has yie!ded a countrate significanity different from background.
A copy of the safety precautions to be employed when using the PuBe soun:e is attached (see ottachment #7) as well as our general policy on radioactive materials
- ).

lI d ~' i [ A NOTE TO 114E INSTRUCTOR !f The experiments described here are designed to familiarize the student with the practical problems involved in nuclear physics experiments. A set of y typical results is included with each experiment. These results were obtained using a 107 neutrons /second Pu Be source. The Irrad iation Facil ity L. used was identical to yours, except that its diameter was 19" rather than ls l* 24". The diameter was increased to obtain better shielding. A commerc ial ly available proportional counter was used to obtain counting data. IJ !i' . A few comments on Experiments IV and V are in order: A. The overage energies of the neutrons omitted by various sources 1t varies somewhat. Thus, different shapes of the r2A versus r curve (Experiment f V) may bo found with dif ferent sources. il l} B. A thorough theoretical treatment of these experiments would be l' j lengthy and, we feel, beyond the scope of this manual. i The treatment here emphasizes the physical mechanisms in a non-mathematical f ashion. C. Finally, your students may be able to obtain an appro<imate value of A, in contrast to the experiment in the manual, since your f acility is larger in diameter than that used in the manual experiments. Th is is because one needs large values of r to evaluate A without encountering edge f offects. ( Act ivit ies measured near the conta iner edge wi ll be icwer than 4 o expected because of increased local neutron leakage near the edge. ) l r \\ It L, F r
t. ? s\\ A n ~- ATOMIC LABOR.ATORIES, INC., aces claremont Ave., Eerkeley s, calwornia j l Subelcitary Cenoo Instruments Corporation I v' I SPECIAL NOTICE l The NEUTRON PEAM IRRADIATION FACILITY is designed to hold any of the various Plutonium-Beryllium Neutron sources well as other types of sources loaned out to educational inst itut ion 4 by the Atom ic Energy Comm iss ion. Sinct d if f erent sources have d if ferent d imensions, the vertical tube whien contains the source has an inner diameter of I 5/3", wide enough to hold the largest source. Some sources will necessari-have a smaller diameter and will have to be positioned inside the * ;bs by wrapping cardboard or some other sof t wrapping material around them. The wrapping can be held in place by scotch tape. All sources must be pos it ioned vertically by means of a wire. The center of the source must be suspended at the center line of the horizontal tubes. Once the wire is marked the proper distance the sotree must then bo lowered into the vertical tube and the long polystyrene cylinder placed down the tube with tha wire in milled groove. To )ld the source in the proper position, place a large nail t '1o i he wa - some convenient' distance from the top of the vertica' tube and loop th 's around the i nail. i it is understood that the Lucite foil ho. 'es m "a he in place et all times in the four horizontal tubes. For an extra..easure of safety, however, it would be a good idea to lower the source into the bottom part of the vertical tube af ter each experiment. For this purpose, an extra 3" of tube has been provided below the conter line. NOTE: At present 7 types of Plutonium-Berylliun sources are available to educational institutions by the Atomic Energy Commission. They are offered in ranges of 1,2,3,4,5,7, and 10 curs of Plutonium. The smallest source has a cylindrical diamets slightly over 1" and a cylindrical length of slightly over i I /2'. The dimensions of the 10-curie source is 1.6" x 3.45", respectively. It is advisable that the purchaser of the Neutron Beam Irradiation Facility obtain the 4C curie source since the experiments in the experiment manuel are based on a neutron y ield of 8 x 100 neutrons /second =---. The $1 curie source / meets these speci f ications. l / I
~. l. a e : Radiatlon Precautions The Atomic Laboratories Neutron Beam !rradiation Facility has been designed to serve two purposes: it aliows safe, permerent sterage of the Plutonlum-BeryiIlum Source; and it serves many purposes in neutron physics experiments (see ] experiments beginning on page 3). When using the facility as a Neutron Source storage container, the four Lucite { foil holders n.ust be in elece e.s well as the Polyethelene cylinder. The lid on t each of.the four beam poi rs must bt. locked. The key, which fits all locks, must remain in the possession of a trusted' individual, preferably the. chairman of the Physics Department. Refer to Atomic Energy Commission's Regulation 10-CFR, part 20, for. procedures involved in the safe storage of the Neutron Source. No special maintenance is necessary in regard to the Neutron irradiation Fac i l ity. Extreme heat might cause the paraf fin wax to melt, but even if it does, it will not leak through the rontainer or get into the foil holders,. Polyethelene cylinder, or Neutron Source. Under no conditions must the wax be. removed since this will take away the shielding and expose students to extremely dangerous doses of rad iat ion. When the f ac il ity is f u l l of wax, it fully compiles with alI the standard Iimits in regard to radiation protection. Computed Flux at 30 cm. from 1.4 x 106 neutronc/sec source.
- 1. 4 x 106
-tx = 123 x e.126(30) Flux = g 4x (30)2 = 123 x (.023) # 3.0 n/cm2 sec. (Computed attenuation 2.3% compared to 45 gIvcn by Frank R. Jones, Pad iolog ical Health Handbook (1955), page 282.) Operation j When the Neutron irradiation Faciiity arrives, it shouId be unpacked caref'uIly y and the entire apparatus inspected to see that there is no shipping damage. The p wax should be within i 1/2" of the top of the container and should appear to be [ solid and welI packed. The beam port locks should be tested and the battery in the lock on the Iid checked. When the Iid is open, a red Iight warning is l visible. The Lucite. foil holders must be examined, and it is wise even t.o check I the Polyethelene cylinder to see if it is in one piece. Only after the facility I and its accessories have been thoroughly checked should the Neutron Source be [ placed within the apparatus. [ The special Indium, Cadmium, and Rhodium Foils should be placed in the foil holders as described in the ind ividual experiments.
l ~ l% i l' UNDER MO CONDITIONS SHOULD ANYCNE STAND IN FRONT OF AN OPEN BEAM PORT WHEN TFE l LUCITE FOIL HOLDERS ARE Pa.1CVED CR WHEN THE BEAM PCRT LOCK IS REMOVED. Only a short exposure under such a condition will result in poss ib le radict ion damage. The same precautions should be taken against sitting on top of the Radiation l Facility if the Polyethelene cylinder is removed. l< Plutonium-Be-v i l ium Source P Due to the Atomic Energy Connission's educational grants for nuclear physics training, colleges purchasing the Neutron Beam Irrad iat ion Fac i l ity wi l l be able to rent a standard Plutonium-Beryllium Source f ree of charge. Such sources emit 1.4 x 106 neutrons /sec and have a 24,000 year hal f-l if e. Less than 0.7 gammas per neutrons are emitted. I Plutonium is a special nuclear material and its receipt, possession and use is licensed in accordance with Title 10, Code of Federal Regulations, Part 70, "Special Nuclear Material". The application for a license for a plutonium-ll beryllium source should be submitted to the U.S. Atomic Energy Cormnission, L Division of Licensing and Regulation, Washington 25, D. C. In letter form in quadruplicate and contain the inf ormat ion required in Section 70.22 (attached), includ ing your procedure for leak test ing the source, the f requency of these 7] tests, and the procedure for preventing axposure of ind ividuals to rad iation. l l App!! cation for renting a Plutonium-Beryllium Source f ree of charge can be i obtained by writing: Mr. C.
