The probaility that a certaun radioactive atom would get disintefrated in a time equal to the mean life fo the radioactive sample is

Text Solution

Verified by Experts

Since , the Probability P(t) that a particular radioactive atom gets disintegrated in a time (from Eq.) is given by `P(t) = 1 - e^(-lamdat)`
`:. ` Here ` t = lt t gt 1 = 1/lamda :. P(t) = 1 - 1//e`
`~~ 1 -0.37 = 0.63`
