Unformatted text preview: t ) The halflife of a radioactive substance is the time necessary for the number of nuclei to reduce to half the original level. Since n denotes the original level then half this number is n / 2. The point in time when this occurs we denote t 1 / 2 . Hence n 2 = n e ( t 1 / 2 t ) 1 2 = e ( t 1 / 2 t ) ln 2 = ( t 1 / 2 t ) . . . t 1 / 2 = t + ln 2 = t + . 693 Usually, t = 0 and so t 1 / 2 = . 693 These results are illustrated in Fgure 2.11....
