The half-life of 131 I is 8 days. Given a sample of 131 I at time t = 0, we can assert that
- no nucleus will decay before t = 4 days
- no nucleus will decay before t = 8 days
- all nuclei will decay before t = 16 days
- a given nucleus may decay at any time after t = 0
Answer
(D) a given nucleus may decay at any time after t = 0
