A radioactive sample has an activity (A ) in air. If the sample is kept inside water, then its activity (A^ )
Options
- Abecomes less than (A )
- Bbecomes more than (A )
- Cis same as (A )
- Dwill be less than or equal to (A ) depending on the density of water
Correct answer
C. is same as (A )
Step-by-step solution
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 ( (A^ ) ) remains same as in air. i.e., (A^ =A )
