The problem of the effects of low level radiation doses

The complexity of the low dose problems and the only possible path to a solution are shown, ie the characterisation of molecular steps on the path of the generation of cancers depending on radiation. There is a strong suspicion that faultfree repair processes and endogenous mechanisms causing cancer coexist in human cells, i.e. that they determine the curve of the dose-effect relationship together. Some of the genetic changes determining cancers and their induction due to carcinogenetic effects and the method of action of hormones determining the specificity of textures have been studied for some years. The question of the existence of a threshold of radiation doses having no effect and a great rise in effect at small radiation doses was discussed. (DG)
