9) How many half-lives are required for the number of radioactive
nuclei to decrease to one-ten-thousandth of the initial number?
10. Strontium
90
38
Sr
has a half-life of 28.5 yr. It is chemically similar to calcium, enters
the body through the food chain, and collects in the bones.
Consequently,
90
38
Sr
is a particularly serious health hazard. How long (in years) will it
take for 96.9900% of the
90
38
Sr
released in a nuclear reactor accident to disappear?
