Environmental Health Risk Assessment (EHRA) Calculator

Compute intake, RQ, and ECR automatically per the Indonesian MoH 2012 EHRA guideline. Includes calculation trace, safe limits, and a per-respondent table.

Overview

The EHRA calculator computes health risk from hazardous-agent exposure quickly and accurately, following the Indonesian Ministry of Health 2012 EHRA guideline. Intake, non-carcinogenic Risk Quotient (RQ), and carcinogenic Excess Cancer Risk (ECR) are calculated automatically, so you never build the formulas by hand.
