Hermann Joseph Muller ( ) U.S. american biologist, geneticist 1927 detected mutagenesis of X-rays 1936 regarded cancer as caused by „somatic“ mutation 1946 Nobel prize in medicine 1955 Geneva Conference „Atoms for Peace“ excluded his presentation

9. Polygenic diseases of children with parents exposed
Polygenic diseases of children with parents exposed by Chernobyl fallout
Results of an analysis of the national registry of Belarus in by Lomat et al (Belorussian-Israeli group):
Hematological diseases (6-fold) Endocrine diseases (2-fold) Digestive organs (1.7-fold)

17. Studies of Scherb et al. , Munic, of sex ratios in exposed populations:
By fallout from A-bomb tests in Nevada
By fallout from the Chernobyl accident
In the proximity of nuclear facilities in Europe

20. Conclusions
There is evidence from human collectives that low level radiation induces severe hereditary disorders. This must become again a main matter of concern for radiation protection of workers and from medical exposures.
