Abstract

Gold-198 induced by the JCO criticality accident of 30 September 1999 was measured to evaluate the environmental impact of the neutrons derived from the accident. The number of ¹⁹⁸Au atoms at about 370 m from the JCO site was estimated to be as high as 6 x 10⁶ atoms g^-1. The influence of the accident was observed up to 1400 m. The general trend of the neutron fluence as a function of distance from the site was well reproduced by theoretical calculations. (C) 2000 Elsevier Science Ltd.
