A radioactive substance has a constant activity of 2000 disintegrations/minute. The material is separated into two fractions one of which has an initial activity of 1000 disintegrations per minute while the other fraction decays with `t_((1)/(2))=24` hours. The total activity in both samples after 48 hours of separation is

A

2000

B

1250

C

1000

D

1500

Text Solution

Verified by Experts

The correct Answer is:
A

As constant activity of 2000 disintegration / minute means decay not occur –
Hence option (a) is right.
