Hich Radiation Area High radiation areas are those areas which contain radiation levels such that a person continuously present in the area could receive an exposure in excess of 100 MREM in any one hour.
The 100 MR/HR y
calculated dose line shall be posted with signs bearing the radiation caution symbol and the words, " CAUTION HIGH RADIATION AREA."
,2y II. Restricted Area A restricted area is that into which the radiographer must control di access for the purpose of radiation safety. This boundary must be extended to include those areas containing radiation levels, whic h y
if an individual were continuously present in the area, would g
result in his receiving a dose in excess of 2 MREM in any one hour, U;
This dose cay be controlled in one of two ways:

1.
Wear your film badge at all times during radiography.
2.
Wear it in a shirt pocket, not on an outer garment which you might take off during work hours.
3.
Do not wear *your film badge off work premises - return it to its assigned place at the end of each work period.
The film badge should be stored in a secure area, such as the y
area where other work related personal safety equipment is kept.
This area must be free from x-rays, radioactivity, heat and moisture.
4 Protect your badge from excessive heat and humidity, or from e
getting wet.
5.
Wear a pocket dosimeter at all times during radiography.
g 6.
Be sure to charge the dosimeter at the start of each work shift m
and record the fully charged reading on the Daily Utilization u
Log.
A.
Place dosimeter in charger receptacle, look in the window, o
rotate control on charger until indicator in dosimeter y
reads "0" or lowest obtainable reading.
7.
Read your dosimeter frequently during radiography operatilons.
]y 8.
Do not drop or bump it - this can cause it to discharge.
9.
If you dosimeter read "off scale" on the high (200 mr)end, stop
' ' o work immediately and report to the Radiation Safety Officer or a
E Radiation Safety Superv'isor.
Your film badge must be sent for immediate reporting and you may not work in the radiography program until the report has been evaluated.
_~
j 10.
Carry a working, calibrated survey meter turned on at all times during radiography.
Refer to it constantly to avoid unnecessary 8
exposure, and to confirm source storage or exposure.
ts A.
Turn on meter - the Model 492 requres no warm-up or zeroing.
B.
If the meter has a "zero" position, turn to this and allow 6
a few minutes for the circuits to stablize, then rotate
=
control to set pointer at zero on scale. Turn to most sensitive range and check operation of meter by seeing if m
it reads about 0.2 MR/HR " background".
11.
If meter malfunctions during radiography, retract source and g
o,btain another meter before continuing operations.
Never work p
without a properly working meter.

Supervisor or radiographer, who has been instructed to obtain the g
smears.
I The Mark V leak test kit supplied by Applied. Health Physics, Inc., or
=g the Technical Operations Model 518 kit shall be used to obtain the E
smears, using the following procedure:
e 1.
Use radiation survey instrument at all times when taking smears.
j 2.
Personnel monitoring equipment (film badge and dosimeter) must be worn while taking smears.
3.
Sealed source must not be removed while taking smears.
4.
Remove the polyethylene top containing the cotton tipped y
applicator from the test tube on the Mark V kit.

Add 10 c.c. of water to the test tube and dissolve the wetting agent by shaking the tube.
5 6.
Dampen the cotten tip with the solution and discard the unused

On storage containers, remove the cap and insert the cotten 3
tipped applicator to the bottom of the cavity and carefully g
wipe the surfaces and the bottom of the hole.

m 11.
If there is no indication on the meter, or an indication is no more than 0.2 mr/hr above background, put the plastic envelope with swab in the mailing box with the identification form pro-O perly filled out, mail to the assayer (Applied Health Physics E
or Tech / Ops).
k5 12.
If the swab should indicate more than 0.2 mr/hr, DO NOT MAIL -
E contact your Radiation Safety Urficer for specifid instructions.
l 13.
If the available survey meter does not detect as little as 0.2 mr/hr; but indicates less than 2.0 mr/hr radiation from the swab, you may send the swab via express shipment (parcel shipment, not mail).

Crank source all the way.out to exposure position and back into projector - did it work smoothly? - crank should operate without E
binding at any point, source should move freely in guide tubes.
Note:
Some projectors may have lock mechanisms that secure E
source pigtail - these should be cleaned with solvent g
and air dried, and checked for good operation.
A small 2
amount of graphited lock fluid may be used to insure smooth engagement.
If there is an exposed source connector, check it care-fully with the gauge provided by the manufacturer.
