A radioactive sample has an activity \(A\) in air. If the sample is kept inside water, then its activity \(A^{\prime}\)
- A becomes less than \(A\)
- B becomes more than \(A\)
- C is same as \(A\)
- D will be less than or equal to \(A\) depending on the density of water
Answer & Solution
Correct Answer
(C) is same as \(A\)
Step-by-step Solution
Detailed explanation
Activity of a radioactive sample does not depend on the type of medium in which it is kept. Hence, if the radioactive sample is kept inside water, then its activity \(\left(A^{\prime}\right)\) remains same as in air. i.e., \(A^{\prime}=A\)
