A particular X-ray photon has initial energy of 60 keV when it enters the body. This photon transmits through 30 cm of soft tissue and exits the body. Calculate its energy (in keV) after it has exited the body.

Answer:

E = 7.334 KeV

Explanation:

given,

initial energy = 60 keV

Δ x = 30 cm

[tex]E = E_0e^{-\mu \Delta x}[/tex]

μ(for soft tissue) = 0.7 cm⁻¹ (taken from table)

[tex]E = E_0e^{-0.7\times 20}[/tex]

         E = 60 × 0.1224

         E = 7.334 KeV

energy of x-ray photon after travelling through 30 cm soft tissue in body is E = 7.334 KeV
