ABSTRACT: It is represented the review about the effect of low
doses of ionized radiation on different types of biological objects (Japanese
quail embryos, Aspergillus niger, Spirostomum ambiguum Ehrbg., mezenchim stem cells of mice
bone brain, dry seeds of the highest plants, blood lymphocytes of pilots and
cosmonauts) and water medium. In model experiments under the chronic ionized
radiation in doses comparable with the doses of ionized radiation inside the
orbital space stations and during the flight in interplanetary space was shown
alike with morphological deviations (Japanese quail embryos, Aspergillus niger), the phenomenon of radiation
hormezis (Aspergillus niger, mezenchim
stem cells), the increasing of the germination of seeds, the decreasing of
spontaneous motion activity of spirostoms and DNA damage, chromosome aberrations
and the increased radio-sensitivity to adding radiation load in blood lymphocytes.
These data testified the fact that the definite factor of ionized radiation
effect is the changing of water medium state. Thus under the interplanetary
cosmic flight and long stay on the orbit in the region of magnetosphere the
studying kinds of radiation first effected on the water medium of organism as a
result morpho-functional structures were changed.
