Fraction of surviving sperm-heads as a function of the testicular absorbed dose from 210Po-citrate (open circles) and 125IUdR (closed circles)
Data shown are the average of two separate series for
125IUdR and three for
210Po-citrate. Representative error bars (standard deviations) are indicated. The data are least-squares fitted to a two-component exponential function which give the following expressions for the survival fractions S as a function of the absorbed D:
