Abstract
In order to explore the possibilities of basing a dosimetric technique on the weight response of male albino mice to radiation, the relation between weight changes and amount of radiation was analyzed for each of the first 13 days after irradiation. A linear relation was found between the percent-weight-change and the amount of radiation over the lethal range on each of the post-irradiation days, different constants being characteristic of different days. A formula for estimating dose from information concerning the day on which a given average percent weight change occurred was developed with a relative error of 3%, though this differs for various doses on the several days. Data within sublethal and supra lethal ranges cannot be subsumed under the formulae effective within the lethal range.
