The half-life of radioactive cobalt is 5.27 years. Suppose that a nuclear accident has left the level of cobalt radia- tion in a certain region at 100 times the level acceptable for human habitation. How long will it be until the region is again habitable? (Ignore the probable presence of other radioactive isotopes.)
