To Calculate: The amount of time for which workers should wait before they could enter the room where radioactive isotope is spilled.
Explanation of Solution
Given:
Half-life of radioactive isotope which is spilled in the laboratory is 3 days.
The
Calculations:
In every 3 days, the amount of radioactive spill would reduce by half which means that to reduced by 8 times,
Conclusion:
Hence, the workers must wait for 9 days before entering the room again.
