Investigating the air kerma rate constant for ²⁴¹Am through first principle calculations and simulation

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 Am-241 by various institutions. Therefore, through first principle calculations and simulation, we investigate the air kerma rate constant for Am-241 based on photon energies and emission probabilities reported in literature.
