Radium `Ra^236` has a half-life of 1590 years. How much of the original amount of `Ra^236` would remain after 6360 year ?

A

`1/8`

B

`1/4`

C

`1/16`

D

`1/2`

Text Solution

Verified by Experts

The correct Answer is:
C
Each 1590 years 1/2 of the remaining element would decay . Therefore , for the 6360 years `(1//2)^4` of the original would remain or 1/16 would remain.
