Effects 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...

牧 広利,河 合建一,赤 星光彦:京 都大学原子炉実験所,大 阪府泉南郡熊取町野田,〒590-04 In order to understand the further mechanisms of lethal actions of thermal neutrons, the combined effects of thermal neutrons and several chemical agents which interact with DNA, mainly bleomycin and actinomycin D, have been studied. Marked sensitization was observed with bleomycin even in its lower concentration, while in the case of actinomyci...
متن کاملEffects of thermal neutrons on living cells. III. Estimation of absorbed dose in amoeba irradiated by thermal neutrons.
河 合建一,牧 廣 利,赤 星光彦1京 都大学原子炉実験所,大 阪府泉南郡熊取町 野田,〒590-04 An absorbed dose in amoeba irradiated by thermal neutrons was estimated. Nuclear events following to thermal neutron capture were divided into 6 parts. More than 99% of absorbed dose was estimated to be due to capture ƒÁ-rays. Absorbed dose due to recoil nucleus following to the emission of capture ƒÁ-rays and that due to ƒÀor ƒÁ-rays emitted ...
