The atomic mass number of Radium is `A=226`, its half life is `1622` years. What is the activity of `1g` Radium ?

A

`3.6xx10^(10)Bq`

B

`0.6xx10^(10)Bq`

C

`1.6xx10^(10)Bq`

D

`2.6xx10^(10)Bq`

Text Solution

Verified by Experts

Acitivity `=(dN)/(dt)=lambdaN`
`lambda=(0.693)/(t_(1//2))`
`N=` number of radium atoms
