The Nuclear Regulatory Commission said today it has proposed a 19-thousand-dollar fine against US Inspection Services of Dayton for violations involving radiation overexposure to a worker. The NRC says the violation occurred at a temporary job site in West Virginia on September Ninth. The company uses cameras containing a radiation source for industrial purposes such as identifying flaws in pipe welds. The NRC says the worker received four times the NRC's annual limit for radiation when the employee failed to ensure that the camera's radiation source had returned to its shielded position. The NRC says the company has taken corrective actions to address the issues. The company has until July 15th to either pay the fine or protest it.
