RADIATION PROTECTION (PRELIM)
questions & answers
Health Physics - answer Concerned with providing occupational
radiation protection and minimizing radiation dose to the public
Health Physicist - answer A radiation scientist who is concerned
with the research, teaching, or operational aspects of radiation
safety
RATIONALE - answer The linear noon-threshold radiation dose-
relationship (LNT) for stochastic effect.
MINIMIZE TIME - answer The time of exposure should be kept to a
minimum.
MINIMIZE TIME IN RADIOGRAPHY - answer To reduce motion blur
MINIMIZE TIME IN FLUOROSCOPY - answer To reduce patient &
personnel exposure
RADIATION DOSE - answer It is directly related to the duration of
exposure.
1.38 mGya - answer A radiation worker is exposed to 2.3 mGy/hr
(230 mR/hr) from a radiation source. If the worker remains in that
position for 36 minutes, what will be the total occupational
exposure?
