Nuclear fuel-cycle radionuclides in raptor castings: implications for environmental monitoring.
Our sampling results indicate that raptor castings (regurgitated material containing the nondigestible remains of prey) faithfully reflect the composition of known environmental gamma-emitting radionuclides. The castings are easily obtainable and provide a way to monitor for the presence of biologically available radionuclides. Raptor castings can also provide a useful adjunct to existing monitoring programs where small mammal burrowing into buried waste may occur.
