The disintegration rate of a certain radioactive sample at any instant is 4250 disintegrations per minute. 10 minutes later, the rate becomes 2250 disintegrations per minute. The approximate decay constant is: (Take log 10 l.88 = 0.274)
Text Solution
Verified by ExpertsThe correct answer is:
C
At t = 0 disintegration rate = 4250 dpm
At t = 10 disintegration rate = 2250 dpm
