c. Shielding, film badges and distance
d. Time, distance, shielding and ALARA considerations
◉ 64.5 feet and 456.1 feet
Answer: Using an unshielded 80 Curie Iridium-192 source, at
what distances should the "High Radiation Area" and the
"Restricted Area" boundaries be placed?
a. 64.5 feet and 288.4 feet

c. 105.8 feet and 748.3 feet
d. 64.5 feet and 456.1 feet
◉B
Answer: "Saturation" of a Geiger Muller survey instrument refers
to:
(Answer with A, B, C, or D)
a. A meter that malfunctions as a result of being water logged
b. A survey meter that indicates a false zero reading when
exposed to a high radiation intensity
c. A meter that will not work on Saturdays
d. A meter that is damaged
◉ 189.1 feet
Answer: An Iridium-192 source that was originally 110 Curies has
decayed for 222 days. At what distance from the source should a
radiographer place the "Restricted Area" boundary?
a. 189.1 feet
b. 411.1 feet
c. 119.6 feet
d. 534.8 feet
◉ Ionization
, Answer: Radiation detection instruments measure exposure to
radiation based on the principal of:
a. The inverse square law
b. Mitosis
c. Attenuation
d. Ionization
◉D
Answer: Before the first radiographic exposure, a radiographer
performs a reference survey of his exposure device containing
100 Curies of Iridium-192. During this survey, he observes a zero
reading on his survey meter. The radiographer should:
(Answer with A, B, C, or D)
a. Proceed with radiographic operations as a zero reading
indicates a safe radiation level
b. Assume the exposure device is empty based on the survey
c. Expose the source and perform more surveys to confirm the
survey meter responds
d. Assume the survey meter is not working properly. The exposure
device must be surveyed with another survey meter
◉C
Answer: A radiographer discovers that his pocket dosimeter is
"off scale" during a lunch break. The radiographer should:
(Answer with A, B, C, or D)
