Nuclear Physics and RadioactivityHard
Question
The initial active nuclei of two radioactive substances are same and their half lives are 1 year and 2 year respectively. The ratio of their activities after 6 years will be
Options
A.1 : 3
B.1 : 6
C.1 : 4
D.1 : 2
Solution
Let us assume that the intial total number of
radioactive substances are the same.
Smaple-1 : Half life T1/2 = 1 year
Smaple-1 : Half life T1/2 = 2 year
radioactive substances are the same.
Smaple-1 : Half life T1/2 = 1 year
Smaple-1 : Half life T1/2 = 2 year
