RADIOECOLOGICAL STUDIES OF NORTHERN ALASKA
Results of radioecological studies in Northern Alaska during 1961 and 1962 are reported. Increased amounts of Mn/sup 54/, Zn/sup 65/, Zr/sup 95/--Nb/ sup 95/, Ru/sup 106/--Rh/sup 106/, Cs/sup 137/, and Cs/sup 144/-Pr/sup 144/ were detected in vegetation samples from the Cape Thompson region following the resumption of nuclear weapons testing on Sept. 1, 1961. An increase in Zr/sup 95/-Nb/sup 95/, Ru/sup 106/-Rh/sup 106/, and Ce/sup 144/--Pr/sup 144/ was detected in Cornic ularia lichen samples collected 3 weeks after the initial weapons test and all radioisotope concentrations in 1962 samples achieved levels approximating or exceeding those measured in 1959. Measurements were also made on the concentration of I/sup 131/ and Sr/sup 90/ in animals and plants. Data are tabulated. (P.C.H.)
