1.	What is the mean life (in min.) of `Co^(55)` radionuclide, if its activity is known to decrease `4.0%` per hour? The decay product is non-radioactive. [ln 100 =4.6, ln 96=4.56]
Answer» Correct Answer - [1500] `t_("avg")=(1)/(lambda) " " lambda xx 1 =ln(100)/(96) " " lambda=0.04 hr^(-1)` `t_("avg")=(1)/(lambda)=25 xx60 xx=1500`
