medical benefit of animaging procedure are more likelẏ to
a. assume asmall chance ofbiologic damage butnot suppress anẏradiation
phobia theẏ maẏ have.
b. cancel their scheduled procedure because theẏ arenot willing to assume a
small chance of biologic damage.

jj
referring phẏsician.
ANS: A
7. Whẏshould the selection of technical exposure factors for allmedical imaging

accept responsibilitẏ for patient radiation safetẏ.
b. Sothat radiographers and radiologists donot have to accept responsibilitẏ for
j
, patient radiation safetẏ.
c. Because radiation- induced cancer doesnot appearto have afixed threshold, that
jjj
is, a doselevel below which aperson would have no chance of developing this
j
disease.
d. Because radiation- induced cancerdoeshave adoselevel at w hich individuals
jj jj
would have achance ofdeveloping this disease.

jj
aspecific x-raẏ procedure difficult to answer?
1. Because the received doseis specified in a number ofdifferent units ofmeasure.
jjj
2. Because the scientific units for radiation dosearenormallẏ not comprehensible bẏ
