The formula for a half-life is T1/2 = ln(2) / λ. In this equation, T1/2 is the half-life. The ln(2) stands for the natural logarithm of two and can be estimated as 0.693, and ...

... introduces radioactive decay and decibel levels and explains how to use their
formulas. ... "Half-life means that, if you have 100 pounds of Plutonium-239.
Free online tool to calculate any one of the values from the other three in a half-
life formula as well as to convert between half life, mean lifetime, and decay ...
The radioactive half-life for a given radioisotope is a measure of the tendency of
the nucleus to "decay" or ... so the standard form of the decay equation is: ...
Because of that general formula I don't believe it's necessary to use the lambda.
Say: the growth factor g is 1/2 (since it's half life) and the time t is in years ...
I can do this by working from the definition of "half-life": in the given amount of
time (in this case, 9.45 ... Either way, I will end up dealing with this equation:.
