Detection of fallout 155Eu and 207Bi in a 210Pb-dated lake sediment core / S.R. Joshi and R. McNeely.: En13-5/87-92E-PDF

"This title radionuclides are produced in nuclear weapons' testing in varying amounts. Their modes of formation are as yet not clearly defined. We report the FIRST detection of both these radionuclides in a freshwater lake, McKay Lake in Ottawa, using high-resolution low-energy gamma-ray spectroscopy for Bi-207. We could trace Eu-155 back to mid 1960's. By comparing the fission yields with Cs-137, we propose that Eu-155 is formed via simple thermal neutron fission of U-235 and discount an earlier suggestion that it is formed via fast neutron fission in U-238"--Management perspective/Executive summary.
