The Nuclear Regulatory Commission has recommended the Air Force be fined $102,500 for a 1986 spill of highly radioactive americium-241. It was the first time the NRC had ever proposed fining a military agency. Lt. Col. Michael Turner, Wright-Patterson Air Force Base spokesman, said base officials were still studying the NRC's report and had no comment. The Air Force has 30 days to pay the fine or contest it. The agency accused the Air Force of two violations: failing to report the spill within 24 hours, as NRC rules require, and allowing an individual to be overexposed to the chemical. On Sept. 18, 1986, base workers opened an unmarked barrel in a building on the base, spilling the radioactive powder on the floor.
