WebAug 13, 2024 · The second half-life has an activity of half the previous count (not the initial count). Equation 11.2.1 can be used to calculate the amount of radioactivity remaining after a given time: N t = N 0 × ( 0.5) number of half-lives. where N t = activity at time t and N 0 = initial activity at time t = 0. Webhalf-life is the amount of time taken for a quantity of isotope to be reduced to half its initial mass; initial mass = 200 gm. after one half-life cycle, mass =200/2= 100 gm. after two half cycle, mass = 100/2 = 50 gm. therefore: 200 gm to 50 gm includes 2 half cycle. given: total time taken by isotope to reduce from 200 gm to 50 gm =60 min. so: high liver enzymes overweight
