ChpECODINST 5100.3A 06 JUN 1984 METHODS FOR CONTROLLING ACCESS TO RADIOGRAPHIC AREAS 1.
General Requirements a.
All areas controlled for radiation safety purposes shall be restricted and posted by radiographic personnel.
In radiographic operations, with by-product material or x-ray machines, all areas where a person could receive two mrem or more in any one hour or 100 mrem or more in any seven consecutive days shall be posted and restricted with standard
" CAUTION - RADIATION AREA" signs and barrier rope or tape.
b.
In addition, all areas where a person could receive 100 mrem or more in any one hour shall be similarly restricted and posted with the " DANGER - HIGH RADIATION AREA" signs.
This will generally result in two separate perimeters, an outer one for the restricted area and the inner one for the high radiation area.
Methods for determining perimeter locations are specified in paragraph 2.
Where both perimeters essentially coincide, such as c.
in a shielded compartment or space, the " CAUTION or DANGER -
ENTERING HIGH RADIATION AREA" sign may be posted at all accesses.
d.
In cases involving actual or potential exposure of unmonitored personnel, emergency actions of enclosure (9) shall be followed.
2.
Temporary Area Control.
a.
Temporary restricted area perimeters shall be established so as to result. in !the. lowest posdible radiation exposures outside the area, but shall not be so unnecessarily large as to interfere with adjacent work or traffic.
Normally these perimeters will be posted at the two mrem /per hour level.
b.
With the specific approval of the Radiation Safety Officer, the radiation dose rate at a temporary restricted area perimeter may exceed two mrem /hr during an exposure, if the total dose during any one hour does not exceed two mrem, according to the number and duration of exposures in an hour.
For instance, if two five minute exposures are made per hour in the same location where the dose rate at the perimeter is 10 mrem /hr during the exposures, the dose during an hour will total about 1.7 mrem at the perimeter and.will thus be less than the 2 mrem in one hour limit if no other exposures are made during the hour.
The radiation dose rate should not exceed 10 millirem / hour, especially when using a collimator.
ENCLOSURE (5)
^
CAPECODINST 5100.3A 06 JUN 1984 h
NOTE:
When any._ type collimator is used, a significant factor in.the dose calculations is the time required to crank the source to the end of the source guide tube and back.
Estimates of the dose during this unshielded condition should be included in the calculation.
c.-
Predetermine the approximate location of the high radiation area perimeter based on curie cohtent of the source, colliraator beam direction, time distance and shielding.
Use barrier rope (preferably yellow and magenta) and post with signs stating " DANGER - HIGH. RADIATION AREA".
(Tne use of amplifying information such.as " Radiography in Progress" in addition to this sign is authorized.)
d.
Predetermine approximate location of the temporary restricted area perimeter, and post barrier rope and warning signs stating "CAUT ION - RADI ATION AREA".
e.
Always ensure.that the area is evacuated of all unauthorized personnel.
~
f.
If a general announcing system is available, pass,-
word warning personnel of radiographic operations in progress, and of the. location of the temporary restricted area.
This should be repeated every 15 minutes until radiographicoperationsarecomgeted.
g.
Whenever possible, physically lock doors that provide access to the restricted ' area and ensure that an appropriate caution sign is posted on the outside of the door.
~
h.
When it is not possible to lock a door, a guard or specially trained monitor shall be stationed to prevent personnel access at the temporary restricted area perimeter.
1 1.
Verify th'e temporary restricted area perimeter by radiation surveys during the first exposure and adjust as necessary.
J.
In all cases, however, the high radiation ayea accesses shall be under continuous direct surveillance.
Surveillance should be maintained from a vantage point which i
provides the least possible radiation exposure.

CAPECODINST 5100.3A 06 JUN 1984 PROCEDURES FOR OBTAINING LEAK TEST RESULTS C
1.
Leak Testing Radiographic and Radiac Calibration. Sealed Sources.-
gg
-:. p a.
Leak testing of radiographic sealed sources' will be performed only by qualified radiographers approved by the Senior Radiographer using the instructions provided (;Ln enclosure (16).
- ,3 Leak testing of radiac calibration" sealad sodrces
~
b.
will be performed only by qualified Radiological Control Division personnel, attended by qualified radiap calibration technicians using the instructions provided in enclosure (16).
e, 2.
Procedure to be Followed by Radiological Control Division for Obtaining Leak Test Results.
.a.
.The equipment used to evaluate leak test sedars is the standard Navy beta counting system consisting of a CP-793 n
radiac computer-indicator utilizing a Type 7840 e
Geiger-Mueller (GM) tube shielded by a Model LS-6 Technical Associates counting chamber.
The accessory equipment associated with this system for calibration and source checks includes a Sr-90/Yt-90 calibration source set and an aluminun n
absorber set.
The minimum sensitivity of this system is approximately 3.3 x 10-5 uc, with an accuracy of + 20 percent at a background count rate of 20 CPM or less.
-b.
Determining Radiation Background.
h,
-(1)
Beta Counting System.
Cosmic rays and natural sources of radioactivity in the GM tube detector, lead shield, and surrounding atmosphere as well as nearbyfsources of gamma radiation will be detected by the GM tube and produce counting rates (C /tb) from a few CPM up to'several b
hundred CPM, depending on the radiation levels in surrounding areas.
Background radioactivity should be determined prior to counting samples as specified below.
(a)
Count background for 20 minutes each day. '
Determine the background count rate (C ) and record both Cb b
and tb (the background counting time for each scaler and the time of day background was countBp9 (b)
Periodica~lly while counting samples, count background for one minute as a rough check of validity of assuming background constant or slowly changing.
O ENCLOSURE ~(17)
s CAPECODINST 5100.3A 06 JU N 1984
[t (c)
If the one minute checks of background indicate that the back, ground count rate has changed more than 20 percent from the previous 20 minute backgroundacount rate, the cause of the change should be eliminated or shielded.
If the background count rate cannot be returned to normal, a new 20 minute background count rate should be determined.
,ni (d)
If the one minute checks of background indicate that the background count rate is constant, background need not be redetermined prioe to counting each sample.
Although the background radioactivity determination theoretically should be performed under conditions that will duplicate the geometry of the sample radioactivity, determination, the additional effort of obtal'ning multiple background determinations using the various planchets is not always warranted.
Background determinations may be made without placing an empty sampi
, container in the lead shie.1d.
(e)
Check of Scaler Discrimination.- The discrimination level of the scaler should be maintained at 0.25 volts for standard GM tube counter operation.; At initial installation, the discrimination level sho,a ld be checked, and if necessary adjusted to 0.25 volts + 10 percent.
m (f)
Initial Calibration Check.
'In r' der to ensure' accurate determination of sample activities, calibration of (he counting system must be checked at initial 3
installation of the equipment and periodically thereafter.
The Sr-90/Yt-00 reference source set can be used. to check the calibration of the GM tube counter system in the following manner:
1.
Set HIGH VOLTAGE ADJUST ontrol qn scaler to obtain 1T00 volts.
Mount source marked,3 (10,000 CPM deposited in one inch planchet) in Recess No.,,1,of the sampic positioning shelf.
Place the shelf in Posi, tion 1 marked on the tube mount.
.t c
2.
Count,,the source for five minutes to stabilize the GM tube.
3.
Remove source, count background for 20 minutes and determTne the count rate.
4.
Place Source No. 3 in Recess No. 1 of the sample positioning shelf.
Place the shelf in Position 3 on the tube mount.
Count the source for five minutes and determine count rate.

Mount source marked C (10,000 DPM deposited on filter disc in two indh aluminum pan) in Recess No. 3 of the sample positioning shelf.
Place the shelf in position 3 marked on the tube mount.

8.
The sour'ce count rate minus background 3
count-rate,hould Ee within the range of values for Source No. 1C as g von in NAVSHIPS 0967-804-6010.
9.
If'the count rates obtained in 5 and 8 are.within 'he limTts specified'in Table 1, the* system is in proper cali: cation.
If one of the count rates obtained in 5 or 8 is no t within the limits specified, count Sources B anH 2 for 20 ano 10 minutes respectively and also compare their count rator with the values given in Table 1 (of the enclosure).
If three of the fouP7 sources f all within the limits spec fied, the system shall also be considered to be/

EMERGENCY PROCEDURE FOR l
- c 1 i.n.
l MERCURY LEAKAGE FROM THE TS-1216()/UD RADIAC' CALIBRATOR 1.
Discussion.
Mercury, because of its liquidiformeand high density, is used as radiation shielding material.inathe TS-1216C/UD radiac calibrator.
The volatilization ofieven small amounts of mercury can produce unacceptable levels of air contamination, with the posssibility of serious effects on personnel inhaling the air.
Skin contact with mercury can also be dangerous.
This emergency procedure has been prepared to emphasize the need for careful, handling of mercury, and to establish steps to be taken should its leakage from the radiac calibrator occur.
A radiation hazard may also occur simultaneously with mercury leakage _ from the radiac calibrator.
pa 2.
Symptoms.
Leakage of mercury from its reservoir. fin the radiac calibrator will normally be detected in ohe t or.smore of the following ways, listed in their probable ordernofa detection.
- uukidh w mor a.
Mercury level indication light will be out.;6This -
symptom may also be caused by a burned-out lamp,. blown fuse,
or securing of the power supply.
l
,5 b.
Radiation intensity at the surf aces of theD. calibrator i
j will exceed the normal level of two mR/hr.
an n~
l c.
Mercury will be visible in the lower portion of the i
calibrator enclosure or on the deck under the calibrator.
d.
Concentration of mercury vapor in the air will exceed 0.05 milligrams per cubic ~ meter, as measured by a vapor '
detector.
3.

Decontaminate the af fected area by washing (down with lime sulfur (calcium polysulfide) and water t solution", being careful to avoid contacting any bare metal surface 37 unnecessarily.
This treatment will convert any? residual traces of mercury to inactive mercuric sulfide.
Add four ounces of lime sulfur concentrate to each gallo~n water to -
make the lime sulfur solution.
