Possible Radioactive Leak Investigated At Washington Nuclear Site (upi.com)
Authorities are investigating radioactive material found on a worker's clothing one week after a tunnel collapse at the waste nuclear waste site in the state of Washington. Around 7 p.m. Thursday, Washington River Protection Solutions, a government contractor contractor in charge of all 177 underground storage tanks at the nuclear site. detected high radiation readings on a robotic device that seven workers were pulling out of a tank. Then, contamination was also discovered on the clothing of one worker -- on one shoe, on his shirt and on his pants in the knee area.
"Radiological monitoring showed contamination on the unit that was three times the planned limit. Workers immediately stopped working and exited the area according to procedure," said Rob Roxburgh, deputy manager of WRPS Communications & Public Relations said to KING-TV. Using leak-detection instruments, WRPS said it did not find liquid escaping the tank. "Everybody was freaked, shocked, surprised," said a veteran worker, who was in direct contact with crew members. "[The contamination] was not expected. They're not supposed to find contamination in the annulus [safety perimeter] of the double shell tanks."
Washington's attorney general, urging a federal clean-up of the site, insists "This isn't the first potential leak and it won't be the last."

Sure, but you don't set such limits to detect catastrophes. You set such limits to detect unforeseen circumstances that might, perhaps in rare situations, lead to catastrophe.
A worker being exposed to harmful levels of radiation is catastrophic. A worker being exposed to a level of radiation that is medically harmless but which should not have occurred is a situation that requires investigation, because that means something about your assumptions isn't quite right. That doesn't mean you ought to panic; in any sensibly conservative procedure you have to accept that false positive concern is a routine event -- as in your story of the smoke detector.
