SUMMARY
The mass of 1μCi of 241Am can be calculated using the relationship between activity (A), decay constant (λ), and the number of nuclei (N). The decay constant λ is determined using the formula λ = ln2 / T1/2, where T1/2 for 241Am is 432.2 years, resulting in λ = 5.09 x 10-11 S-1. The final calculation for mass yields approximately 2.4 x 10-7 grams. It is crucial to remember that 1 Ci equals 3.7 x 1010 disintegrating nuclei per second for accurate conversions.
