    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.)
