CADORmed: a tool for internal dose assessment

Abstract

Abstract CADORmed is a free bespoke Excel® tool for committed effective dose assessment using latest dose coefficients from ICRP OIR publications. The field of application of CADORmed is special monitoring, and it is not available for the dose assessment of chronic exposure. Calculations are made according to EURADOS guidelines and principles (EURADOS report 2013-1). The Chi-squared test for the goodness of fit is made with a scattering factor for type A and type B errors according to the EURADOS report. The Intake is calculated with the maximum likelihood method. Measurements that are below the detection limit are incorporated by the use of an allocated value equal to one-half or one-quarter of the detection limit. The Identification of rogue data can easily be achieved. Advanced options may also be used: mixed ingestion and inhalation, mixture of default absorption types, correction for DTPA treatment, calculation with a new intake and adjustment when the date of intake are unknown. The validation of the tool has been included in the work plan of EURADOS WG 7. The validation plan has been defined and the validation tests completed. All changes are traced in a Quality Assurance document.
