Explanation:
We have the equation:
NN = current number of radioactive nuclei remainingN_0N0 = starting number of radioactive nuclei remainingtt = time passed (ss though can be hours, days, etc.)lambdaλ = decay constant(ln(2)/t_(1/2))(ln(2)t12) (s^-1s−1 , though in the equation uses the same unit of time astt )
