Abstract : Further investigations were made of the chemical dosimetry method in which the decrease of the optical activity is measured in d(plus) maltose solutions that have been exposed to gamma radiation. An equation for the action of gamma radiation on d(plus) maltose solutions was derived statistically and can be used for calculating the sage of high levels of radiation. The d(plus) maltose chemical dosimetry method, and the equation developed for the calculations were found to be accurate for sources with dose rates of 3.6 x 1000,000 to 1.0 x 10 to the 6th power rads/hr. and when subjected to total exposure doses of 2.40 x 10 to the 7th power rads to 7.20 x 10 to the 7th power rads. Data concerning the post irradiation effects on the optical activity of solutions are presented. Additional results of investigations into the chemical reactions involved by these irradiations are also presented. (Author)
