Radiation Protection (PRELIM) Questions and
Answers| Latest Update
What are the three categories of dose limitations established to regulate radiation exposure
Patient/Medical
Occupational
General Public
ALARA stands for As Low As Reasonably Achievable
the time of radiation exposure is kept to a minimum to reduce motion blur
most effective cardinal principles of radiation protection distance
if the radiation response increase in severity with increasing radiation dose and occurse within
days after the radiation exposure, it is called deterministic effect
If the incidence of the radiation response increases with increasing radiation dose, it is called
stochastic effect
10 commandments of radiation protection 1. Understand and apply the cardinal principles
of radiation control: time, distance, and
shielding.
, 2. Do not allow familiarity to result in false security.
3. Never stand in the primary beam.
4. Always wear protective apparel when not behind a
protective barrier.
5. Always wear an occupational radiation monitor
and position it outside the protective apron at the
collar.
6. Never hold a patient during radiographic
examination. Use mechanical restraining devices
when possible. Otherwise, have family or friends
hold the patient.
7. The person who is holding the patient must
always wear a protective apron and, if possible,
protective gloves.
8. Use gonadal shields on all people of childbearing
age when such use will not interfere with the
examination.
9. Examination of the pelvis and lower abdomen of
pregnant patients should be avoided whenever
possible, especially during the first trimester.
10. Always collimate to the smallest field size
appropriate for the examination.
