RADIATION cataracts which have occurred in cyclotron workers and in persons exposed to the atomic bombs are said to have been caused, in part at least, by the fast-neutron component of the radiation.1 It is therefore of considerable practical moment to know the cataractogenic dose of neutrons as exactly as possible under a variety of conditions and to compare the neutron effects on the lens with those on other tissues and with the effects of other forms of radiation.
The biologic action of neutrons has been studied in a variety of tissues, ranging from such relatively simple systems as hatching Drosophila eggs and germinating wheat seedlings2 to carcinoma in human beings.3 It is generally conceded that neutrons have much the same qualitative effect on tissue as do x-rays and other ionizing radiations,4 but the effects produced by different amounts of neutron radiation do not necessarily vary
