The rate at which radiation was delivered to fathead minnows (Pimephales promelas) was found to affect survival time. For a dose of 3000 rad, the time to 50% mortality at 2.62 rad/min was over 60 days, at 37.8 rad/min it was 28 days, and at 1730 rad/min it was 17 days. At a dose rate of 1730 rad/min the 50% endpoint for mortality at 12 days was independent of dose from 6000 to at least 24,000 rad. These results further substantiate that dose rate has a significant effect on the survival time in fish, if the environmental temperature is constant.
