Question
Disintegration constant of a radioactive material is λ
Options
A.Its half life equal to 
B.it mean lift equals 
C. At time to mean life, 63% of the initial radioactive is left undead
D.After 3-half lives, 
rd of the initial radioactive material is left undecayed
rd of the initial radioactive material is left undecayedSolution
N = N0e-λt ⇒ 
= N0e-λT1/2
⇒ T1/2 =
⇒ Tmean = 
= N0e-λT1/2 ⇒ T1/2 =
⇒ Tmean = Create a free account to view solution
