Half-life of radioactive sample is \(24 \mathrm{~h}\). If a newly prepared radioactive sample shows 4 times the allowed and safe value of radio activity, the minimum time after which one can work safely with the source is
- A 48 h
- B 96 h
- C 8 h
- D 72 h
Answer & Solution
Correct Answer
(A) 48 h
Step-by-step Solution
Detailed explanation
Newly prepared radioactive sample shows 4 times the allowed and safe value of radioactivity, so on reaching to the allowed and safe value, its radioactivity will be reduced to \(\left(\frac{1}{4}\right)\) th of the current value,…
