Question: mr doe recorded an initial activity reading of 24 rads...
Mr. Doe recorded an initial activity reading of 24 Rads, after 60 days the current activity reading is 23.909 Rads. Calculate the half-life of the radiation source in years. Please use the following equation and please show work...I can't remember how to do this at the moment.
A(t) = A(o)*e-[0.693t/T1/2]
At = current activity (curies).
Ao = original acivity (curies).
e = 2.71828 (base of the natural logarithm system).
λ = decay constant simplified to
t = elapsed time between Ao and At.
