Radioactivity is one of the most important topics of Modern Physics. It is important to have a thorough knowledge of all the three rays i.e. alpha, beta and gamma rays. Solving problems of gamma decay in Modern Physics is not a very tough task but requires clarity of concepts. We discuss here some questions on calculation of decaying constant. Consequently, radioactive elements including plutonium, iodine, strontium and caesium were scattered over a wide area. In addition, the graphite blocks used as a moderating material in the RBMK caught fire at high temperature as air entered the reactor core, which contributed to emission of radioactive materials into the environment.

Ø They are emitted from a radioactive material after the beta decay. Ø They are negatively charged particles. Ø They carry one unit negative charge. Ø They move with a velocity of 2.36 X 10^8 to 2.83 X 10^8 cm/second. Ø They are less ionizing. The ionizing power of beta particles is far less than that of alpha particles.
