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:
  • S(125IUdR)=0·46 e−D/0·41+0·54 e−D/22·1,
  • S(210Po)=0·30 e−D/0·20+0·70 e−D/15·6.
