Experimental results are presented from a 60 day hydroponic experiment which investigated the simultaneous effects of potassium concentration in solution and plant age on both potassium and radiocaesium (137Cs) uptake by bean plants (Vicia faba) from

Estimates have been made of the reduction in dissolved oxygen levels in coastal waters that would result from the disposal of contaminated milk following a radiological accident. Two contrasting sites were chosen: the Bristol Channel near Hinkley Poi

A lysimeter experiment was carried out on a relatively infertile soil to examine the effect of potassium fertiliser application on the uptake of radiocaesium by spring wheat. Porous ceramic cups were used to obtain samples of soil solution. Results s

Short term experiments were carried out to investigate the effect of internal tissue potassium concentration on the uptake of radiocaesium by spring wheat (Triticum aestivum cv. Tonic). The results showed that potassium starvation increased Cs influx

An assessment of the possible future incursion of marine sediment inland in Cumbria and Lancashire has been carried out. The assessment indicated that material from the patch of clay and silt offshore from Sellafield would not be readily mobilised an

A study has been carried out to determine soil-plant transfer factors relevant to fruit crops. The current default values for137Cs, Pu and Am used in the NRPB food-chain model FARMLAND were generally higher than the TFs observed. Lower values would b

The potential importance of inadvertent ingestion of soils as a route of intake of radionuclides by grazing animals has been recognised for many years. The process has been taken into account in radiological assessment models such as FARMLAND, the fo

The absorption of 137Cs by sheep following ingestion of contaminated soil was studied using an established dual isotope method. Two agricultural soils were studied: an alluvial gley contaminated by discharges to the sea from the Sellafield Reprocessi
