On May 3, 2006, a Notice of Violation and Proposed Imposition of Civil Penalty in the amount of $16,250 was issued for a Severity Level III problem composed of six violations of NRC requirements involving the licensee's failure to conduct operations such that the dose in an unrestriced area from external sources, exceeded regulatory limits. The most significant of these violations involved the radiation exposure of five employees and contractors, who were not radiation workers (and therefore considered members of the public), who received radiation doses in excess of the regulatory limit of 100 millirem in a year, i.e., they received estimated doses ranging from 103 millirem to 197 millirem.
