CADORmed: a tool for internal dose assessment

Area of Science:

• Medical Physics
• Radiation Protection
• Computational Toxicology

Background:

• Effective dose assessment is crucial for radiation protection.
• Existing tools may not incorporate the latest ICRP dose coefficients or handle specific monitoring scenarios.
• Standardized methodologies are needed for reliable dose calculations.

Purpose of the Study:

• To introduce CADORmed, a free Excel tool for committed effective dose assessment.
• To provide a tool for special monitoring applications using updated ICRP OIR dose coefficients.
• To implement calculations according to EURADOS guidelines and incorporate advanced data handling techniques.

Main Methods:

• Bespoke Excel tool development.
• Application of ICRP OIR dose coefficients.
• EURADOS 2013-1 guidelines for calculations.
• Chi-squared goodness of fit test with scattering factors.
• Maximum likelihood method for intake calculation.
• Inclusion of data below detection limits using allocated values.
• Advanced options for mixed exposures and unknown intake dates.

Main Results:

• CADORmed is validated and available for special monitoring.
• The tool accurately calculates committed effective dose using current standards.
• It facilitates the identification of rogue data and incorporates advanced exposure scenarios.
• Measurements below detection limits are handled appropriately.

Conclusions:

• CADORmed provides a robust and flexible solution for committed effective dose assessment in special monitoring.
• The tool adheres to established EURADOS guidelines and incorporates advanced statistical methods.
• Its features support accurate dose assessment even with challenging data, including values below detection limits.
