The half life of `I""^(131)` is 8 day. Given a sample of `I""^(131)` at t=0, we can assert that

The half - life of I^(131) is 8 days. Given a sample of I^(131) at time t = 0 , we can assert that

The half life of .^(131)I is 8day. Given a sample of .^(131)1 at t = 0 , we can assert that:

The half - life of I ^ (131) is 8 days. Given a sample of I^(131) at time t = 0 , we can assert that

The half - liofe of ^(131) 1 is days Given a sample of ^(131) 1 at time t = 0 , we get that

The half-life of I^131 is 8d. If a sample of I^131 is taken at time t=0, then it can be said that (A) No nuclear disintegration will occur before t=4 d. (B) No nuclear disintegration will occur before t=8 d. (C) all nuclei will be disintegrated in t=16 d. (D) A definite nucleus may be disintegrated at any time after t=0.

The half-life of Radon is 3.8 days. Define half-life.
