A Review of the Speciation and Foodchain Availability of Plutonium Accidently Released from Nuclear Weapons - RP0222

This review will draw together available literature on the speciation of Pu released from a weapons accident and how the knowledge can be used to predict uptake into the foodchain. The review will look at past accidents and information from Nagasaki for information on the chemical forms of Pu, and due to the relevance to the UK meterological and agricultural situation.
The final objective of this work is to put together in one source an account of the current knowledge of the speciation of Pu dispersed from a nuclear weapons accident. In order to assess the total radiation dose to man from Pu released in weapons accidents, ot is necessary to consider the movement of this radioelement through the foodchain. For this evaluation to be made, a comprehensive database of transfer factors is required of the various likely chemical forms that might result from the entry of Pu into the environment from a weapons accident.
