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 = 3.7xx10^(10)` decays per second, activity `=5.13xx10^(7)Ci`
`=5.13xx10^(7)xx3.7xx10^(10)Bq=1.9xx10^(18)Bq` Since, `1xx10^(6)` decay per second `=1 Rd`
Activity `=1.9xx10^(18)Bq=(1.9xx10^(18))/(1xx10^(6))Rd=1.9xx10^(12)Rd.`
