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
[tex]x-ray\ fluence=exposure\times time[/tex]
Put the value into the formula
[tex]x-ray\ fluence=200\times0.2[/tex]
[tex]x-ray\ fluence=40\ mRs[/tex]
We need to calculate the energy fluence
Using formula of energy fluence
[tex]E_{f}=40\times10^{-3}\times75\times10^{3}[/tex]
[tex]E_{f} = 3000\ J[/tex]
We need to calculate dose -equivalent delivered to the bone, muscle, and fat
Using formula of dose
[tex]D=\dfrac{E}{t}[/tex]
Where, D = dose
E = energy
t = time
Put the value into the formula
[tex]D=\dfrac{3000}{0.2}[/tex]
[tex]D=15.0\ kJ[/tex]
Hence, This is the required solution.
