FILES - Picture taken on February 25, 2006 shows shows the entrance of the uranium enrichment plant Urenco in Gronau, western Germany. A leak in the plant exposed an employee to a high level of radiation but posed no danger to people outside the facility, the firm operating the plant said on January 22, 2010. The employee was taken to hospital as a precaution, a spokeswoman for Urenco, a German subsidiary of a British nuclear firm, said.
