The air kerma rate constant is important for estimating radiation dose and shielding calculations to ensure radiation exposure is as low as reasonably achievable (ALARA). Currently, there are significant deviations in this constant reported for ²⁴¹Am by various institutions. Therefore, through first principle calculations and simulation, we investigate the air kerma rate constant for ²⁴¹Am based on photon energies and emission probabilities reported in literature.

通过第一原理计算和模拟研究²⁴¹ Am的空气比释动能速率常数

空气比释动能常数对于估算辐射剂量和屏蔽计算很重要，以确保辐射暴露尽可能低（ALARA）。当前，各个机构报告的该常数在²⁴¹ Am时存在明显偏差。因此，通过第一原理计算和模拟，我们根据文献报道的光子能量和发射概率研究了²⁴¹ Am的空气比释动能常数。
