Trace-level plutonium in the environment often comprises local and global contributions, and is usually anthropogenic in origin. Here, we report estimates of local and global contributions to trace-level plutonium in soil from a former, fast-breeder reactor site. The measured <sup>240</sup>Pu/<sup>239</sup>Pu ratio is anomalously low, as per the reduced <sup>240</sup>Pu yield expected in plutonium bred with fast neutrons. Anomalies in plutonium concentration and isotopic ratio suggest forensic i ...[more]
