Accident on board of Sovjet submarine ECHO II

Description

On 26 June 1989 a Sovjet nuclear submarine met with a reactor accident in the Norwegian Sea, caused by breakdown in the primary coolant circuit. The report describes the emergency response in Norway, and data are given on radioactivity in the air. Calculations limit the inhalation of radioactive iodine for the population in northern Norway to 1 Bq. The highest dose to the thyroid gland of crew members on Norwegian surface vessels is estimated to 1.6 mGy. It is concluded that individual exposure in Norway due to the accident is negligible. 11 refs.; 5 figs.; 8 tabs
