Thefts from a secure area at Los Alamos National Laboratory are raising concerns about security at the federal facility.
The lab reported tools stolen on at least three occasions from Technical Area 54, the largest waste disposal zone on the lab's campus in northern New Mexico.
Police reports obtained by The Santa Fe New Mexican say impact wrenches, weed trimmers and other tools were reported stolen between May and August and remain missing.
A national expert on radiation exposure says the tools likely pose little health risk but could be dangerous if they were exposed to toxic chemicals present in the area where the tools had been used.
Los Alamos police were forced to close the case because the lab refused to give investigators the names of workers who had access to the area.
