Q.4. Uranium dioxide (UO,)is an oxide of uranium used in nuclear fuel rods in nuclear reactors. Calculate the mass attenuation coefficient of UO, for 1 MeV gamma rays. The density of UO, is 10 g/cm. What is their mean free path? Mean free path length (A-lambda), which is the mean distance a particle or photon travels between interactions.
