15 صفحه اولEffects of thermal neutrons on living cells. 1. Lethal effects of thermal neutrons on amoebae.
Lethal effects of thermal neutrons were compared with those of 60Co-ƒÁ-rays on the two types of Amoeba proteus. D37 doses against ƒÁ-rays were 2.5 •~ 105 (M-type) and 7.2 •~ 105 rads (P type), and those for thermal neutrons were 9.1 and 11.7 •~ 1013 n. cm-2 (total flux) respectively. Additions of AET, D2O or boron failed to increase or decrease the lethal effects of thermal neutrons. The lethal...
