SUMMARY
The partial half-life of 22Na for decay by electron capture (Ec) and beta-plus (β+) emission is determined using the formula λ=ln2/T1/2. The half-life (T1/2) of 22Na is 2.602 years, resulting in a decay constant (λ) of 0.266 yr-1. The discussion highlights the need to reference decay tables to find the percentage contributions of each decay type, which are not specified in the initial inquiry.
