Example 2: On April 26, 1986, reactor 4 of the Chernobyl
Nuclear Power Plant exploded. The explosion released
massive amounts of radiation into the air, particularly
Strontium-90 and Cesium-137. Both of these isotopes have
half-lives of about 30 years. If 5000kg were released inside
the reactor, and only half a kilogram is safe to be around,
when will it be safe for human beings to enter the reactor?
