Question
The radioactivity sample of a sample is R1 at time T1 and R2 at time 2. the half life of the specimen is than number of atoms that have disingrated in time (T2 - T1) is proportional to
Options
A.(R1T1 - R2T2)
B.(R1 - R2) T
C.(R1 - R2) / T
D.(R1 - R2) (T1 - T2)
Solution
N1 = N0e-λT1; N2 = N0 e-λT2
R1 = λN1 ; R2 = λN2
(N1 - N2) =
(N1 - N2) = 
T =
; λ 
(N1 - N2) =
(N1 - N2) ∝ (R1 - R2)T
R1 = λN1 ; R2 = λN2
(N1 - N2) =
(N1 - N2) = T =
; λ (N1 - N2) =
(N1 - N2) ∝ (R1 - R2)T
