Suppose that x rays are emitted from a focal spot isotropically. The photon flux is 3.28x10^6 photons mm^-2 sec^1 at a distance of 0.75m from the focal spot. What is the photon flux at a distance of 10cm from the focal spot? Neglect the effects of air attenuation.© BrainMass Inc. brainmass.com March 5, 2021, 12:27 am ad1c9bdddf
In this solution we compute the photon flux of an X-ray beam at a given distance from its target.
