Comments on the theory of radiation risk II Experiments in biology and the assessment of radiation risk

For pt. I see ibid., vol. 26, no.3, 229-37 (March 1974). An experimental program and a computational program are outlined for obtaining a relationship between transfer, L. Q and linear energy using biological data for critical effects and sets of linear equations can be obtained in which the coefficients are the doses delivered in intervals of L, and the unknowns are 'biological weighting factors', lambda . From these equations one can derive lambda 's for various L's as they relate to critical effects in animals. Using value judgment and combining the calculated results with data observed on men, one can obtain a Q-L relationship which is more directly based on experimental evidence than that which is currently used.
