Samples of surface sand and sand cores were collected from intertidal regions of west Cumbria-between Silloth and Walney Island (including the Duddon Estuary) between 1982 and 1984 and analysed for 238 Pu, 239+240 Pu and 241 Am. Generally, more than

The distribution of radioactivity discharged from Sellafield in Cumbria (north-west England) has been measured against a background of nuclear weapon fallout, with the object of determining the pathways and transfer mechanisms between various environ

In order to study the deposition on vegetation of plutonium arising from the testing of nuclear weapons and discharges from nuclear facilities, sheep faeces were collected from the South-west and North of England. The plutonium content of faeces has

Since 1957, British Nuclear Fuels Ltd. have discharged to the Irish Sea about 18000 Ci of plutonium alpha activity, in addition to other actinides and fission products. Experiments are described which demonstrate that seaspray in the area is enriched

A new method is described for the determination of lead-210 in sediments via its grand-daughter, polonium-210. The polonium is converted to chloride and distilled from the sediment at 500°C in a simple distillation apparatus. The results obtained ar

The measurement of low levels of radionuclides in environmental and biological materials often depends on separation of the nuclide of interest from a bulky matrix containing interfering radioelements. In such case, however sophisticated and elegant

Irradiated urarium was found to evolve H/sub 2/Te when dissolved in HCl, and this reaction was made the basis of a rapid and simple method of separating Te/sup 132/ from most fission products. In this method, 6M HCl and tellurous acid carrier are add
