Q:
Tungsten, W-181 is a radioactive isotope with a half life of 121 days. If a medical lab purchase 24 kg of W-181 how much will be left after 1 year?
Accepted Solution
A:
3 kg because one year is approximately 3 half-lives of W-181. The amount remaining would be 1/23 or 1/8. That is 3 kg of W-181.
