the half-life of the substance, to 2 decimal places is 18.905 years.
The substance's decay constant can be found. multiplying ln 2 by the substance's degradation rate.
The half-life is the length of time it takes for a quantity to decrease by half if its decay is exponential. It is supplied by. Half-life = ln 2 k ln 2 k, half-life
Knowing an element's alpha, beta, or gamma decay can help someone properly protect their body from excessive radiation. Within one half-life, the amount of radioactive nuclei present at any particular time will be reduced to half.
remaining after each year: 100 - 3.6 = 96.4%
Solve for t in
1/2 = (0.964)t
t = log(1/2) / log(0.964) ≅ 18.905 years
t1/2 = 18.905 years
