Abstract
Radiation effects on the living beings are generally divided into two categories: deterministic and stochastic effects. Deterministic effects are those whose severity increases as dose increases. The level of damage on the cell structure particularly depends on the radiation dose received. Stochastic effects of radiation are independent of absorbed dose and under certain exposure conditions; the effects may or may not occur. There is no threshold and the probability of having the effects is not proportional to the dose absorbed. Curability of the effect has little to do with the dosage of radiation received [1].Gamma rays are penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei. It consists of photons in the highest observed range of photon energy. Gamma rays typically have energies above 100 keV, and therefore have frequencies above 10 exahertz (or >1019 Hz) and wavelengths less than 10 picometers, which is less than the diameter of an atom [2].
