An X-ray with energy 60 keV strikes a gadolinium-based intensifying screen, producing photons at a wavelength of 415 nm. The energy conversion coefficient for the process is 20%. How many photons are produced for each incident X-ray? (Planck's constant = 6.63 x 10^-34 J s, 1eV = 1.602 x 10^-19 J.)© BrainMass Inc. brainmass.com March 5, 2021, 12:38 am ad1c9bdddf
This solution shows how to calculate the number of photons produced for each incident X-ray, given the X-ray's energy, wavelength, and energy conversion coefficient.
