Internal Dose Help
Screening-only scope
Internal dose tools in HPCalc are for documentation/training support and conservative screening workflows.
They support intake × coefficient, ingestion, inhalation, DAC-hours, and ALI fraction screening summaries.
They do not perform regulatory intake evaluation, official dose assignment, or medical determination.
Tool overview
- Intake × coefficient: committed effective dose estimate from intake and selected coefficient.
- Ingestion: ingestion-focused screening input wrapper around the same coefficient model.
- Inhalation: known-intake mode or air concentration × breathing rate × time mode.
- DAC-hours: airborne concentration relative to DAC over duration.
- ALI fraction: intake compared against ALI for route-specific screening context.
Value origin and documentation
Tabulated values come from bundled starter datasets and keep their confidence labels.
User-supplied values require source note documentation before export and should include a source type when available.
Source types: manual-lookup, procedure, dosimetry-review, vendor, conservative-assumption, other.
Confidence labels
Coefficient and limit selections carry the same confidence vocabulary as elsewhere in HPCalc (validated, reference-derived, illustrative, user-supplied, placeholder).
Illustrative and placeholder starter data are for training and workflow demos—do not treat them as facility-approved coefficients without independent verification.

What internal dose screening does not do
- No certified internal dosimetry.
- No bioassay interpretation.
- No organ dose modeling.
- No full biokinetic modeling.
- No medical evaluation logic.
- No regulatory dose assignment decisions.
