The number of electromagnetic field (EMF) sources is steadily increasing, and workplace exposure assessment is becoming more complex due to a wider spectrum of higher harmonic components. This creates a need for accurate and automated evaluation of EMF parameters for electrical personnel. While software tools exist for estimating electric and magnetic field strengths, practical tools for calculating EMF energy-based indicators remain limited. This paper presents an original software tool for automatic calculation of key EMF energy characteristics at workplaces, including EMF energy load, total energy load, daily dose of potential EMF exposure energy, and specific daily dose of potential absorbed EMF energy. The tool accepts harmonic-component inputs for electric and magnetic field strengths, frequency, and exposure time, as well as anthropometric parameters required for dose-related computations. The application was implemented in C# using Windows Forms and includes input validation (missing values, numeric format, and consistency of component lists) to reduce user errors. The calculation results are provided through a user-friendly interface suitable for routine occupational safety assessments. The outputs were verified against an independent spreadsheet implementation for representative test cases, showing agreement within rounding error. Ultimately, the developed application enhances the reliability of occupational safety protocols and facilitates rapid decision-making in complex electromagnetic environments.
