Webb13 jan. 2016 · 2n = 16 ⇒ n = 4 Therefore, four half-lives must pass in order for the activity of the sample to go from 880 Bq to 55 Bq. Since the number of half-lives can be thought of as n = given period of time half-life = t t1/2 you can say that t1/2 = t n This will get you t1/2 = 160 minutes 4 = 40. minutes Answer link WebbHalf-life is defined as the time needed to undergo its decay process for half of the unstable nuclei. Each radioactive element has a different half life decay time. The half-life of carbon-10, for example, is only 19 seconds, so it is impossible to find this isotope in nature. Uranium-233 has a half-life of about 160000 years, on the other hand.
