medical benefit of an imaging procedure are more likely to

receive from a specific x-ray procedure, the radiographer can
ff ff ff ff f f ff ff ff f f

ff f ff ff ff ff ff ff ff ff ff f f
is, a dose level below which a person would have no chance of developing this

10. Why is a question concerning the amount of radiation a patient will receive during a
ff ff ff ff ff ff ff ff ff ff ff ff ff ff
specific x-ray procedure difficult to answer?
ff ff ff ff f f ff
1. Because the received dose is specified in a number of different units of measure.
ff ff ff ff ff f f ff ff ff ff f f ff ff
2. Because the scientific units for radiation dose are normally not comprehensible by a
