Review NMTCB 1.001-1.027
questions & answers
D. is correct.
Minimizing the amount of time spent in a radioactive area,
increasing the distance from a radiation source, and using a
shielding material such as lead, are three practical methods for
reducing exposure from radiation. - answer 1) The three most
important factors to be considered when handling radioactive
materials are:
A. activity, distance, type of emission
B. organ sensitivity, type of emission, distance
C. type of emission, shielding, area of exposure
D. time of exposure, distance, shielding
D. is correct.
ALARA stands for "As Low As Reasonably Achievable" which is a
philosophy to increase awareness and reduce radiation exposure
incorporating reasonable cost in effort to reduce exposure -
answer 2)The ALARA concept in radiation protection refers to:
A. as long as radiation is around
B. personnel can accumulate up to the maximum amount
permitted
C. personnel should be notified by the radiation safety officer if
radiation exposure exceeds the maximum permitted
D. keeping personnel exposure to radiation as low as reasonably
achievable
, A. is correct.
The Inverse Square Law - answer 3) If the intensity of radiation is
10 mrem/hour at 2 meters from the source, the intensity at 8
meters from the source is___________mrem/hour.
A. 0.625
B. 2.5
C. 40
D. 160
D. is correct.
The Department of Transportation controls the packaging and
transportation of materials containing radioactivity. A category II
yellow label is less than or equal to 50 mrem/hr at the surface of
the package and less than or equal to 1 mrem/hr measured at 1
meter distance. - answer 4) Upon arrival, a package containing
radioactive material with a DOT Category II yellow label must
have a dose rate which at the surface does not exceed:
A. .5 mrem/hour
B. 5 mrem/hour
C. 25 mrem/hour
D. 50 mrem/hour
B. is correct.
