6) c programming Case study: In a certain building at a topsecret research lab, some yttrium-90 has leaked into the computeranalysts’ coffee room. The leak would currently expose personnel to150 millirems of radiation a day. The half-life of the substance isabout three days, that is, the radiation level is only half of whatis was three days ago. The analysts want to know how long it willbe before the radiation is sown to a safe level of 0.466 millirem aday. They would like a chart that displays the radiation level forevery there days with message unsafe or sage after every line. Thechart should stop just before the radiation level is on-tenth ofthe sage level, because the more cautious analysts will require asafety factor of 10.
