T1/2 = 0.693*ζ
This formula uses 2 Variables
Variables Used
Radioactive Half Life - (Measured in Second) - Radioactive Half Life is defined as the time required for a quantity of radioactive substance to decay to half of it's initial value.
Mean Life Time - (Measured in Second) - Mean Life Time is the average lifetime of an atomic nucleus in a radioactive sample.
STEP 1: Convert Input(s) to Base Unit
Mean Life Time: 0.00029 Year --> 9151.51608 Second (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
T1/2 = 0.693*ζ --> 0.693*9151.51608
Evaluating ... ...
T1/2 = 6342.00064344
STEP 3: Convert Result to Output's Unit
6342.00064344 Second -->0.00020097 Year (Check conversion ​here)
