This Demonstration shows radioactive decay for the two most abundant uranium isotopes, U-238 and U-235. These have the form of exponential decay:
N(t)=

where
N(t)
is the number of nuclei remaining at time
t
(in years) for an initial number
N

in the sample, and
k
is the decay constant, which is specific to the individual isotope:
k=1.54×

for U-235. Decay graphs of U-238 (in blue) and U-235 (in orange) are plotted. Also shown (in green) is a generic decay curve for the selected decay constant. The red dots mark the half-life of each decay.
