So that means the halflife is just going to be equal. To the natural log of 2 / 1.1 * 10 this two we can put that into our calculator.
What is the half-life period of a radioactive substance?
In radioactivity, Half-life is the interval of time required for one-half of a radioactive sample's atomic nuclei to decay. If half-life passes again, half of the remaining mass will remain. (1/2, 1/4, 1/8, 1/16, 1/32, )
How do you calculate radioactive half-lives?
The time taken for half of the original population of radioactive atoms to decay is called the half-life. This relationship between half-life, the time period, t1/2, and the decay constant λ is given by t12=0.693λ t 1 2 = 0.693 λ .
How long is radioactive decay?
If the half-life of an isotope is relatively short, e.g. a few hours, most of the radioactivity will be gone in a few days. If the half-life of an isotope is relatively long, e.g. 80 years, it will take a long time for significant decay to occur.
