An assessment of the distribution of Chernobyl fallout in a Swedish forest was carried out and showed more than 95% of the 137 Cs in the system to be of Chernobyl origin. The data show that approximately 87% of total fallout is found in soils, 6% in

The activity concentrations of 137Cs,238 Pu, 239,240Pu and 241Am were measured in root mat and vegetation samples collected from tide washed pastures in 17 estuaries spanning the eastern seaboard of the Irish Sea, extending from the Solway in north-w

Environmental releases of low levels of radioactivity can occur as a consequence of normal operations at nuclear facilities. In England and Wales, the impact of gaseous discharges on the terrestrial environment is monitored routinely by the site oper

Red grouse eat a natural diet mostly of heather, a dwarf shrub which accumulates radiocaesium. Captive grouse were fed a diet, comprising 60% heather contaminated with Chernobyl radiocaesium, containing about 1500 Bq kg−1 of radiocaesium. Intake an

Heather (Calluna vulgaris) dominates large tracts of the United Kingdom and fire is used as a management tool to encourage new growth. Heather contaminated with radiocaesium from the Chernobyl accident was burnt under controlled conditions giving a

This review summarizes the findings of a research programme in the UK following the Chernobyl accident. The projects provide a degree of integrated coverage of environmental transfers of radiocaesium from cloud deposition through studies of soil chem

Samples of cloud and rain water, soil and vegetation were collected from sites at up to 847 m altitude on Great Dun Fell in northern England during the period 2–6 May 1986. Wet deposition is the dominant depositional process for 103Ru and the caesi

The concentrations of 134Cs and 137Cs originating from the Chernobyl fallout have been measured in the standing vegetation of three upland pastures over a three-year period. An exponential decay curve has been used in the past to describe the concent

The 137Cs, 239,240Pu, 238Pu, 241Am and 40K activities in soils and vegetation under grassland management in west Cumbria were investigated. Uptake of these radionuclides by the vegetation is affected by the land management practices employed. The mor
