Comparison of the Lethal Effect of Fast Neutrons and Gamma-Rays on the Growing Tips of Broad Bean Roots

Abstract

THE growing tips of broad bean roots have been irradiated by D-D neutrons (2·9 Mev.) and by gamma-rays by techniques already described1,2. The duration of irradiation and the variation of intensity along the length of the root was approximately the same for both radiations. The neutrons were unaccompanied by gamma-radiation, and stray X-rays were excluded by 5 mm. of lead surrounding the specimens. The dose was measured and converted into energy units in the manner already described2,3.
