RadAegis 1.6.1 brings a refreshed workspace and important calculation updates for radiation safety and health physics.
- New field-style design, rotating Home illustrations, clearer layouts and improved accessibility.
- Consistent SI and Imperial units across calculators, dose records, charts, ALARA plans and PDF reports.
- Corrected occupational dose totals, with whole-body, lens, skin and extremity readings tracked separately.
- Consistent attenuation and HVL/TVL results using shared NIST photon data, plus corrected shielding and contamination calculations.
- Corrected imaging risk estimates and clarified fluoroscopy dose and patient follow-up guidance.
- Corrected laser hazard distances and RF averaging times. UV tools now distinguish effective UV from unweighted UVA and save the measurement basis in records and exports.
- Reviewed isotope references, corrected inhalation DAC/ALI pairs and clearer display of small intake limits.
- Improved scientific calculator layouts and unit conversions, plus fewer review interruptions.
- With Pro and iCloud sync, review synced records, print reports and export data on a bigger screen at radaegis.fouledanchorsafety.com. Web access is view-only.
