Radiation protection in the world of modern radiobiology: Time for a new approach

A new approach need to be adopted to deal with the problem of radiation protection. Radiation causes significant damage to exposed cells and other biological materials. One of the consequences of radiation exposure of cells is breakage of chromosomes, which indicate DNA double strand breaks. The influence of low doses and low dose rate exposures on the ability of human skin cells, to repair radiation breaks in chromosomes have been tested. It has been revealed that moderate doses at low dose rates reduce the DNA damaging of a subsequent exposure. It has also been found that low dose may increase, decrease, or unable to produce changes in repair of a specific chromosome and genes located on it. These findings have established that a new approach needs to be adopted to minimize exposure to radiation and ensure better radiation protection.
