## State the law of radioactive decay - Radioactivity, Physics - eSaral

Hey, students do you want to know how to state the law of radioactive decay? If yes. Then read this article till the end. Radioactive decay law The rate of decay (number of disintegrations per second) is proportional to number of radioactive atoms (N) present at that time t rate of decay $\frac{-\mathrm{d} \mathrm{N}}{\mathrm{dt}} \propto \mathrm{N}$ or $\frac{\mathrm{d} \mathrm{N}}{\mathrm{dt}}=-\lambda \mathrm{N}$ or $\quad N=N_{0} e^{-\lambda t}$.....(1) where $\lambda$ is disintegration cons...
