　　Like everyone else working at the Limerick nuclear-power( 核能)plant，Stanley Watras had to pass through the monitors(监测器)before　　leaving the buildin9.Most of his co-workers.passed through without a　problem，but Watras，an engineer，continually set off alarms(警报).Some　days he was found to be carrying six times more radiation(辐射物)than　normal.

　　Neither Watras nor his co-workers could understand where he was　picking it up.

　　Then one day Watras went through the door at Limerick and turned　and walked back through the monitors without ever entering the power　block.Yet the machines still said he was carrying radiation.“If I wasn’t　picking up radiation at work,there was only one place it could be coming　from：my house.”

　　When scientists came to test the Watrases’home in the countryside，　they found out what was the matter.The house contained so much　radon(氡)that living in it for a year was like being exposed(暴露)to 260，　000 chest X-rays.In the year the Watrases had spent there，they had　increased their chances of getting lung cancer(癌症)by 13 or 14 percent.

　　The next day the Watrases took down their Christmas tree，put their　clothes in some bags and moved into a nearby hotel.“It was terrible，”　　says Watras.The owner of the Limerick plant took charge of dealing with the

　　Watrases ’ radon problem as an experiment.Scientists studied every　comer of the house.When the ground was dug up，　　they found that under　　the house there was a uranium(铀)-beating rock.

　　C.he proved one day he wasn’t picking up.radiation at work
