Rutherford and Soddy.s laws of radioactivity explain the rate of decay of radioactive material. Arrive at the expression for the number of radioactive atoms of a radioactive material remaining after an interval of time.

State radioactive decay law.

The decay rate of a radioactives ample is called its activity. What is the SI unit of activity?

The half-life period of a radioactive material is 5 hours. In how much time 15/16 of the material will decay?
