[Comparison of the effect of gamma-radiation and fast neutrons on the biosynthesis of DNA in rat bone marrow in different stages of proliferation].
In experiments with rats of different age exposed to gamma- or neutron-radiation it was shown that in younger animals, the inhibition of DNA synthesis in the bone marrow was of a lesser degree but more stable without a tendency toward recovery. Inhibition of DNA synthesis was more pronounced in mature rats, but in 18 h it was completely or partially eliminated. Neutrons of 1.5-2 MeV caused a more pronounced, than gamma-radiation, inhibition of DNA synthesis in all animals under study irrespective of their age: the inhibition was similar in animals with different levels of bone marrow proliferation.
