A study of the radioactive decay law

Abstract

The decay of radon has been followed in effect over approximately 40 halflives in an effort to detect any deviation from the exponential decay law. The results were fitted to a decay of the form N=N0 exp(- lambda t(1+bt)) and b was calculated to be (1.9+or-1.0)*10-6 d-1+ the halflife was determined to be 3.82351+or-0.00034d.
