Question
The alpha ray activity of a material is
measured after equal successive inter-vals
(hours), in terms of its initial activity as
unity to the 0.835; 0.695; 0.580; 0.485; 0.405
and 0.335. Assuming that the activity obeys
an exponential decay law, find the equation
that best represents the activity and
calculate the decay constant and the
half-life.??????
