Tolerances of Several Marine Species to Co 60 Irradiation

Mean lethal dose-time curves are used to describe the radiation tolerances of 6 species of marine teleosts and 2 species of marine invertebrates. These curves describe radiation tolerances better than the commonly used LD50 (30 day) values since they show changes in LD50's with increasing time after irradiation. In addition, these curves are very useful as guides in experimental design.
