A radioactive sample of half-life 30 d contains `10^12` particles at an instant of time. Find the activity of the sample.

Text Solution

Verified by Experts

Decay constant, `lambda=0.693/T=0.693/(30xx24xx60xx60) s^(-1)` and `N=10^12`
`therefore` Activity, `A=lambdaN=(0.693xx10^12)/(30xx24xx60xx60)=2.67xx10^5` dps
