A dental X-ray typically affects 212 g of tissue and delivers about 3.4 uJ of energy using X-rays that have wavelengths of 0.024 nm. What is the energy Ephoton, in electron volts, of X-ray photons? Ephoton = e V How many photons, N, are absorbed during the dental X-ray? Assume the body absorbs all of the incident X-rays. N = photons
