Problem 6.221

A U \(^{238}\) preparation of mass 1.0 g emits \(1.24 \cdot 10^{4}\) alphaparticles per second. Find the half-life of this nuclide and the activity of the preparation.

Reveal Answer
T=4.5109 years, A=1.2104 dis./s. T=4.5 \cdot 10^{9} \text { years, } A=1.2 \cdot 10^{4} \text { dis./s. }
