Title: Evaluation for Emergency Planning of Hazards from Accidents Involving Stocks of Radioactive Materials
Abstract: In formulating plans to deal with possible accidents at a nuclear research establishment relationships are needed between the quantities of radioactive materials held in buildings and the hazards which might develop downwind if the materials were involved in fires, explosions or similar incidents. This paper considers these relationships in two stages. Firstly, figures are given for the amounts of some commoner radioisotopes which if released to atmosphere could give rise to exposure above defined reference levels necessitating urgent emergency action at distances up to 100 m from the point of release. These amounts are called site hazardous releases. Secondly, the fractions of stocks of radioactive materials which might be released to atmosphere from a building under accident conditions are considered, and these combined with the site hazardous release quantities are used to define site hazardous stocks. Comparisons between these figures and actual stocks held enable the buildings on a site to be classified in order of potential hazard. Consideration is also given to the contamination of milk and crops in the case of accidents involving strontium-89, strontium-90, iodine-131 and caesium-137.
