An analytical tool for calculating kerma-to-dose equivalent average conversion coefficients ((10),(3),(0.07), and ICRU 95 recommended dosimetric quantities) for photon beams defined in ISO 4037-1, diagnostic, therapy beams, unfiltered x-rays, and custom photon spectra.

Radiation protection for workers in diverse environments, exposed to varying radiation fields, is a critical aspect of occupational health and safety. To address the challenges in personnel dosimetry, this study introduces excel for kerma-to-dose equivalent conversion (EKDEC), a user-friendly, Excel-based analytical tool designed to calculate the kerma-to-dose equivalent average conversion coefficients for a wide range of photon radiation spectra. EKDEC supports the calculation of dose equivalents for the traditional International Commission on Radiological Protection quantities ((10),(3),(0.07)) as well as the newly recommended ICRU 95 dose equivalents, including personal dose (), local skin dose (), and absorbed dose to the eye lens (). The tool is capable of handling photon beams such as those defined in International Organization for Standardization 4037-1, diagnostic x-rays, therapy beams, unfiltered x-rays, and custom photon spectra. Through rigorous validation, EKDEC demonstrates excellent agreement with previously published results, showing relative differences typically within ±5% for most cases. By offering high accuracy, flexibility, and ease of use, EKDEC empowers radiation safety professionals, health physicists, and dosimetry laboratories to perform precise dosimetric measurements. This tool provides a comprehensive solution for enhancing the safety of radiation workers, supporting both standard and custom dosimetry needs with precision and simplicity.
