Exit room and close door. Open control box and crank source out as smoothly and rapidly as possible d.
Durir.g an Exposure 1.
Maintain direct surveillance and do not allow anyone to enter exposure room.
2.
If alarm bell sounds immediately terminate the exposure.
e.
At End of Exposure 1.
Crank source back into carnera as rapidly as possible; return crank to control oox; and lock control box 2.
Enter exposure room observing survey meter. Approach the camera from the lock box side with a survey meter. Staying behind the camera reach around and survey the camera at the outier nipple and then survey the entire length of source tube. The reading at the outlet nipple should be the same noted just prior to making the exposure. Lock the pig-tail in the camera.
If at any time while approaching the camera, higher than normal readings are encountered, only attempt to crank in the source as above. if this fails to decrease the high reading, follow the emergency proe edures below.

ANS: Stop radiation work, notify RSO and submit badge for processing.
3)
Describe what you would do if you were the radiographer at a field site and your survey meter went off scale when you approache:f the camera after cranking in the source.
ANS: Establish an exclusion area at the 2 mrem /hr radiation level; post Radiation Area signs and prohibit anyone frorn entering the area; notify..
the 1750 i..;.

5)
(a) How wou?d you check a survey meter for proper operation?
ANS: Determine the proper needle deflection when the switch is on battery check. Hold the survey meter near a loaded, but secure camera; 1
a reading of 10 mrem /hr to 500 mrem /hr should be obtained depending on the type of camera, source activity and distance from camera.
(b) How frequently must radiography meters be calibrated?
ANS: A survey meter must be calibrated at three month intervals.
6)
What action must be taken if a survey meter reads zero at the outlet nipple when performing the initial survey prior to making an exposure?
4 ANS: A zero reading at the outlet nipple indicates that the survey meter is inoperable.
No exposure must be made umil an operable and calibrated survey meter-is obtained.
s 7)
When is it permissible to leave a radiographic site during an exposure?
ANS:
It is never permissible to leave a radiography site during an exposure since direct surveillance is required to prevent entry of unauthorized personnel.
8)
(a)
How do you determine where to post " RADIATION AREA" signs prior to making the first exposure?
L ANS: The radiographer should estimate the maximum workload during
.a.
the next hour based upon the anticipated number of shots and their 1

9)
(a)
During the daily routine of svaking several radiography exposures.
when must the camera by surveyed?
ANS: Before the first exposi:re the camera is surveyed at the outlet nipple and the reading retainr.d for later comparison. At the end of each exposure, the camera must be surveyed at the same location to determine that the source is properly shielded.

a.
Source Procurement - The Radiation Safety Officer has direct responsibility for all source orders. Each order will be checked against the radioactive material license to verify that it is authorized. Upon receipt of the source, the following action will be taken.
1)
File the original decay curve for reference and leak test record; 2)
Record serial number of device and source (show transfer of old source, if applicab!c); and 3)
Survey camera and record results.
b.
Assignment of Personnel - The Radiation Safety Officer has direct responsibility for assigning radiographers, radiographer's assistants and helpers so there will be an authorized raciographer on each job.
