Textbook Problem

Calculate the dose in Sv to the chest at a patient given an x−ray under the following conditions. The x−ray beam intensity is 1.50 W/m2, the area of the chest exposed is 0.0750 m2 35.0% of the x−rays are absorbed in 20.0 kg of tissue, and the exposure time is 0.250 s.

To determine

The does in Sv to the chest of a patient given an x-ray.

Explanation

Given info:

The intensity

  I=1.50W/m2A=0.0750m2m=20kgΔt=0.250sec

Formula used:

  does=Emdoes=IAΔtm

Calculation:

Substituting the values

  does=1
