Radiation Effect


We have the tendency to think of the biological outcomes of radiation in their effects on existing cells. For little levels of exposure to radiation, the biological outcomes are very small that they can not be noticed. The human body contains repair devices against damage stimulated by radiation and also By means of chemical carcinogens. 
As a result, biological outcomes of radiation into living cells can result in 3 outcomes: 

1) damaged or injured cells fix themselves so that there will no more damage left; 
2) cells expire, much similar to millions of cells in the body do each day, being substituted by means of normal biological procedures; or 
3) cells repair wrongly themselves which result in biophysical change.

The duration of time amid exposure to radiation and the growth of cancer is called the dormant period and may be for many years. Those tumors that can develop as the outcome of exposure to radiation are not distinguishable from cancers that happen naturally or as an outcome of the exposure to other forms of chemical carcinogens.
