Problem 6.224

Calculate the specific activities of \(\mathrm{Na}^{24}\) and \(\mathrm{U}^{235}\) nuclides whose half-lifes are 15 hours and \(7.1 \cdot 10^{8}\) years respectively.

Reveal Answer
3.21017 and 0.8105dis/(sg) respectively. 3.2 \cdot 10^{17} \text { and } 0.8 \cdot 10^{5} \operatorname{dis} /(\mathrm{s} \cdot \mathrm{g}) \text { respectively. }
