y = a(1-r)^x
a is initial amount.
r is rate of decay.
x is the number of time intervals that have passed.
if you need more explanation, i want you to follow the related link.

The power formula for radioactivity is given by P = λ*N, where P is the power, λ is the decay constant, and N is the number of radioactive atoms. This formula represents the rate at which energy is released by radioactive decay.
The rate cannot be changed.
The rate of nuclear decay increases as the temperature of a radioactive sample increases. This is due to the increased kinetic energy of the nuclei at higher temperatures, which facilitates interactions that lead to nuclear decay.
Decay rate is a chemical property, as it relates to the rate at which a substance undergoes chemical reactions or transformations over time.

Check the time between your first decay rate and when the decay rate reaches half this number. Half life T1/2 is calculated using the below formula T1/2=0.6931/r Where r is disintegration constant

Decay rate and rate of regrowth
Statistically carbon-14 atoms decay at a constant rate.

In the wild it will decay and turn into plantlife When buried in a coffin it will decay, but at a slower rate When mummified, it will decay at an even slower rate When air-locked (stuck in tar, wrapped up, etc.) it won't decay at all

The math is exponential functions and continues half life. The formula is f(t)=a*e^(kt). You would need to find out the decay rate of the carbon 14 found in living tissue. A is how much C-14 you start with and t is the time. K is the rate which comes from the formula F(x)=a*b^x. B=R-1. R is the percent of decay. Ln(b)=k
