**Abstract:** Benford's law states that the first digits of a large body of naturally occurring numerical data in
decimal form are not uniformly distributed but follow a
logarithmic probability distribution. The values of
radioactive decay half lives, which have been accumulated
throughout the present century and vary over many
orders of magnitude, afford an excellent opportunity to
test the predictions of this law. To this end. we examine
the frequency of occurrence of the first digits of both
measured and calculated values of the halflives of 477
unhindered alpha decays and compare them with the
predictions of Benford‘s law. Good agreement is found,
and a similar distribution law for second digits is also
considered.
