Ukrainian border police stopped a wagonload of radioactive materials near Hungary’s border with Ukraine on Thursday, local border guards spokesman Vasil Yarmeliuk told MTI.
The train was carrying 60.5 tonnes of zirconium from Italy to Russia, but was stopped at Solovka, near the Hungarian border, as a test showed higher-than-acceptable radioactivity levels in its shipment.
The cargo had no legal documents for hazardous materials pertaining to transit through Ukraine, Yarmeliuk said.

This is not a delibrate act. Often mined materials are contaminated by natural isotopes making them unsellable. This is often the case.
