Answer to Question #94397 in Atomic and Nuclear Physics for Achal jose

Question

A radioactive material decays to (1/16)th of its inital amount in 2hrs. What is the half life of the sample?

Answer 1

N=N₀*2^(-t/T); N=N₀/16; t=2 hours; N/N₀=2^(-t/T); t/T=log₂(N₀/N); T=t/log₂(N₀/N); T=0.5 hours = 30 min
