a1 a1 a1 a1 a1 a1 a 1 a1 a1 a1 a 1 a 1 a 1 a1 a1


ficx-ray procedure difficult to answer?
1a a1 a1 a1 a1


1. Because the received dose is specified in a number of different units of measure.
a1 a1 a 1 a1 a1 a1 a1 a1 a 1 a1 a 1 a 1 a1


2. Because the scientific units for radiation dose are normally not comprehensible by a pati
