Promethium 146
WebThe half-life of Promethium-146 was determined to be 2024 plus or minus 18 days. The radionuclide was produced by a p,n reaction on enriched Nd146. The decay of the purified Pm146 was followed on both beta-ray and gamma-ray counters. The gamma-ray energies were determined from pulse-height distribution curves obtained with a GeLi detector. … WebPromethium-147 is used as a beta particle source and a radioisotope thermoelectric generator (RTG) fuel; its power density is about 2 watts per gram. Mixed with a phosphor, …
