1. What acronym represents the fundamental radiation
safety principle used in
radiation therapy?
A. ALARA
B. OAR
C. DVH
D. HVL - ANSWER-A. ALARA (As Low As Reasonably
Achievable) is the fundamental radiation
,safety principle—the lower the dose received, the lower
the risk of the individual
irradiated.
2. The three principles of ALARA include:
A. Personnel and facilities monitoring
B. Time
C. Neutron contamination
D. Distance
E. Shielding - ANSWER-B, D, and E. For external beam
exposure, ALARA can be achieved by following
the rules of time, distance, and shielding.
, 3. Regarding radiation protection for photon beams , which
of the following would
have the greatest effect to minimize dose?
A. Double the shielding
B. Double the time
C. Double the distance
D. All of the above would have an equal effect -
ANSWER-C. Time has a direct relationship, so the less
time exposed, the less dose
received. Distance, on the other hand, has an indirect
relationship—increasing
distance from radiation source, decreases dose. In this
instance, the Inverse
