Effects of low level ionising radiations

Like non-ionising electro-magnetic radiation, the ionising radiation is an essential part of our life. Not only is it present in our surroundings but its presence within our body makes it an inseparable component of living. An average person of about 60 kg body weight continuously emits around 24,000 gamma rays photons every minute which arise primarily from the radioisotope of potassium, [40K] with natural abundance of 0.12% of natural potassium. This article focus on the human data on radiation effects rather than the biological experiments on which large amount of information is available
