1. Most personnel overexposures could be prevented by D
performing a radiation survey:
A: at the restricted area perimeter
B: before a radiographic exposure
C: before shipping or transporting the exposure de-
vice
D: after a radiographic exposure

2. 10 CFR Part 34 requires that an industrial radiograph- C
er:
A: complete 40 hours of formal training in radiation
safety each year
B: have at least 960 hours of on-the-job training
C: be certified by a certifying entity
D: have at least one month on-the-job training

3. When the source is in a source storage or shipping A
container, the container shall have no radiation levels
in excess of:
A: 200 mR/hr at contact with any exterior and 10 mR/hr
at a meter from any exterior surface
B: 50 mR/hr at 6" from any exterior surface of the
device
C: 50 mR/hr at contact with any exterior and 10 mR/hr
at a meter from any exterior surface
D: 200 mR/hr at contact with any exterior surface and
50 mR/hr at 6" from any exterior surface

4. The process of surveying the circumference of an ex- C
posure device and along the guide tube is required:
A: whenever the device is first approached in storage
B: in order to complete the utilization log

C: in order to determine whether or not the source is
fully retracted
D: but the exposure device requires a survey of all six
sides

5. The biological effect resulting from exposure to gam- A
ma radiation would be greatest from:
A: a single total effective dose equivalent of 150 to 200
R
B: six total effective dose equivalent events, each of 30
to 50 R, over a period of 5 years
C: low level, total effective dose equivalent events over
a prolonged period of time
D: a single 450 R shallow-dose equivalent exposure to
the extremities

6. Other than date and location of use, which of the fol- A
lowing is information required in a utilization log?
A: Name of radiographer, make, model and serial num-
ber of exposure device
B: Name of radiographer, serial number of the survey
meter
C: serial number of the sealed source, serial number of
survey meter
D: Make, model, and serial number of exposure device,
and distance to restricted area boundary

7. Which of the following are required to be worn by A
radiographers and assistants in field radiography?

ter
D: Film badge, pocket dosimeter, TLD

8. An advantage of the fountain-pen type of ionization B
chamber (pocket dosimeter) is that it:
A: provides a permanent record of accumulative dose
B: provides an immediate indication of dosage
C: is the most sensitive indication of dosage
D: works independently of the survey meter

9. The standard dose rate emission (Gamma Ray Con- C
stant) from a radioisotope is commonly expressed as:
A: roentgens per hour per curie
B: roentgens per hour per curie per foot or per meter
C: roentgens per hour per curie at one foot
D: roentgens per second per curie

10. What is accelerated toward a high atomic number tar- A

A: Electrons
B: Neutrons
C: Protons
D: Nuclei

11. When exposure devices containing radioactive mater- B
ial are stored overnight in a mobile laboratory at a job
site, the mobile laboratory must have signs bearing
the radiation symbol and the words:
A: "CAUTION, RADIATION AREA" or "DANGER, RADIA-
TION AREA"
B: "CAUTION, RADIOACTIVE MATERIAL" or "DANGER,
RADIOACTIVE MATERIAL"
C: "CAUTION, RADIOACTIVE STORAGE AREA" or "DAN-
