Abstract
We have compared the decay rate of freshly prepared K-40 to that of K- 40 that is > 4.5 x 10(9) years old. We find that to within the experim ental uncertainty of +/- 11%, the decay rates are the same. This indic ates that the exponential nature of the decay law is valid down to tim e-scales of approximately 10(-10) t(1/2).
