The nuclide 131 I is radioactive, with a half‐life of 8.04 days. At noon on January 1, the activity of a certain sample is 60089. The activity at noon on January 24 will be
Text Solution
Verified by ExpertsThe correct answer is:
C
Number of days from January 
to January 
days.
Number of half lives 
In three half lives activity becomes 75 
, but the given number of half-lives are lesser than 3 so activity becomes greater than 75
