Occurrence of plutonium in the terrestrial environment at Thule, Greenland
Samples of air, resuspended particles, water, soil and precipitation were collected in an area 10 km south of the Thule 1968 impact point and analysed for their content of 241Am and plutonium. The results from the soil sampling show a very inhomogeneous distribution with hot spots ranging up to seve...

| Summary: | Samples of air, resuspended particles, water, soil and precipitation were collected in an area 10 km south of the Thule 1968 impact point and analysed for their content of 241Am and plutonium. The results from the soil sampling show a very inhomogeneous distribution with hot spots ranging up to several hundred kBq per m2 of Pu. Although concentrations in surface soil can be very high the concentration in analysed air filter samples and passive aerosol collectors are very low. Exposure to plutonium due to inhalation of airborne plutonium particles in the area is of little importance according to this study. To further assess the risk of inhaling resuspended material particles isolated from the different hot areas have been subject to investigation on stability and leaching behaviour. |
