Abstract
MOTTRAM1 claimed that the effect of ionizing radiation on the growth of bean roots was greater in the presence of oxygen or in the cold (∼ 0° C.). Since then the oxygen effect has been confirmed by Read2 and shown in a wide variety of materials. No comparable generalization has been established, however, for temperature. Giles, Beatty and Riley3, investigating chromosome structural changes in Tradescantia, have stated that radiosensitivity is affected by temperature differently under conditions of aerobic and anaerobic irradiation.
