MAMMALIAN RADIOSENSITIVITY.

Abstract

A critical appraisal is given of the data currently available on LD50/30 for mammals. A re-evaluation of data from two previous reports as well as newly obtained data was done. This resulted in a sub-division of mammals for the purposes of predictor slopes into two groupings, rodents and mammals other than rodents. Predictor slopes of the latter, mammals other than rodents, were excellent. The rodents, however, displayed some unusual features. The female rodent species gave a slope which agreed with previous slopes of Sparrow and co-workers on plants indicating the larger the interphase nuclear volume, the more sensitive the mammal was to ionizing radiation. The male of the rodent species gave opposite type of slope which indicated that the larger the interphase nuclear volume, the less sensitive the animal was to ionizing radiation. The male rodent slope was analogous to the slope obtained for mammals other than rodents. Several interpretations and explanations are given. (Author)
