O15 water half life
Web13 de ago. de 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.

Web14 de may. de 2024 · The half-life of O15 was measured using the β-Counting Station at the University of Notre Dame's Nuclear Science Laboratory. Our new result, t1/2=122.308 (49) s, is the most precise determination ... WebThe half-life of O15 is 2 min. So in 10min, it has undergone 5 half-lives. Remember, it’s asking you how much has decayed not how much is left. So it goes from: 1 -> 1/2 -> 1/4 -> 1/8-> 1/16 -> 1/32 Only 1/32 is left after 5 half lives... so that means 31/32 already decayed. barelysurvivinguoft • 5 yr. ago
