A radioactive sample has an activity of ...

A radioactive sample has an activity of `5.13xx10^(7)Ci`. Express its activity in 'becqueral' and 'rutherford'.

Text Solution

Verified by Experts

Since 1 `Ci = 3.7 x 10 ^(10)` decays per second, activity `=5.13 x 10 ^(7) Ci`
`=5.13 x 10 ^(7) x 3.7 x 10^(10) Bq = 1.9 x 10 ^(18) Bq`
Since `,1 x 10 ^(6)` decay per second `=1Rd`
Activity `= 1.9 x 10 ^(18) Bq = (1.9 xx 10 ^(18))/( 1 xx 10 ^(6))Rd`
`= 1.9 x 10 ^(12) Rd.`
