Title: CALCULATION HALF LIFE TIME
Post by: MIK90 on June 30, 2020, 06:04:38 AM
Hi

i am beginner in the field of radioactivity and I have a problem to solve , however I would like your help. I have to calculate half life time of element and I have the activity values ( 400,200, 100 MBq)  and time points (5,4,3 min) .I would like to ask you how I can calculate the half life time with these values. should I use the formula A=Ao e-λt   ??

Do you know the meaning of λ in this formula and how it is related to the half-life?

Is that formula really necessary? Observe the data. 400 - 200 - 100 MBq and 3min - 4min - 5min, does that ring a bell?
