Nuclear Radiation Origin and Benefits

Nuclear Radiation In India
Nuclear radiation has always managed to create a debate in the society and one must be thoroughly aware about its nuances. We live in a naturally radioactive world, in fact the radioactive polonium and radium are present in our bones; our muscles contain radioactive carbon and potassium and there are radioactive noble gases and tritium in our lungs. On the external level we are bombarded by cosmic radiation from the space. As most of it is blocked by the atmosphere of the earth, only a fraction reaches the ground. In addition, over the last century, background radiation has increased infinitesimally because of activities such as weapons testing and nuclear power generation. 

Some consumer items contain radioactive substances and homes are often equipped with smoke detectors containing a tiny alpha-emitting radiation source. The intensity of background radiation depends on many factors: where we live, the composition of the ground, building materials, the season, the latitude and, to some extent, the weather conditions. Rain, snow, high pressure, low pressure and wind directions, all affect radiation levels. It clearly manifests that in spite, of being exposed to radiation all our lives, it is safe in more than one ways and furthermore, it has proved to be highly beneficial for us.
