of Acute Gamma Radiation on Wild Opossum, Gray Fox, Raccoon and Bobcat
F. B. Golley, E. L. Rauber, E. L. Morgan, and J. H.
The radiation response to acute 137Cs
radiation was tested in wild-trapped opossums, raccoons, gray foxes and bobcats
collected on the AEC Savannah River Plant, Aiken, South Carolina.
The LD50/30 for the raccoons and gray foxes was 580 and 710 R
respectively. Data were
insufficient to determine the LD50/30 for the opossums and bobcats;
however, the relationship between average survival and dose indicated that the
opossum appeared to be the least sensitive species tested and the bobcat the
least resistant. In general,
decedent wild mammals did not exhibit symptoms of radiation sickness, other than
anorexia, until several days before death.
Lethality in these wild species was within reported limits for
domesticated or laboratory mammals of approximately the same body weight.
