Explanation:
Given that,
Potential = 75 kV
Exposure = 200 mR
Time = 0.2 sec
We need to calculate the x-ray fluence during this chest x-ray exam
Using formula of fluence
Put the value into the formula
We need to calculate the energy fluence
Using formula of energy fluence
We need to calculate dose -equivalent delivered to the bone, muscle, and fat
Using formula of dose
Where, D = dose
E = energy
t = time
Put the value into the formula
Hence, This is the required solution.
