This paper is a report on our survey of residual radioactivity in the soil of the Semipalatinsk nuclear test site in the former USSR. The soil was sampled at approximately 30 sites along the roads connecting Kurchatov City, ground zero for the first USSR nuclear test, Balapan, Degelen Mountain and Salzhal settlement. The radioactivity levels of Cs, Pu and -Pu as well as the ^Pu/^ 'Pu atomic ratios in the soil were determined. Although Cs was within typical environmental levels except for an area near ground zero, 'Pu was at elevated levels contaminated with weapons-grade plutonium in all areas we visited.
