Radiation Dose Calculator

CT effective dose (ICRP-102), SSDE (AAPM-204), and DRL compliance (EC-RP-185)

Standards-Based Calculation

All dose values are computed using deterministic formulas from ICRP Publication 102, AAPM Report 204, and EC Radiation Protection 185. DRLs are statistical investigation thresholds set at the 75th percentile — exceeding a DRL triggers review, not alarm. Dose calculations are for educational reference only.
