Dosimetric References of the Radionuclide Handbook

The committed effective dose resulting from internal exposure is calculated using the effective dose values per incorporated unit of activity  (in Sv/Bq) defined by the Order of 16 November 2023 defining the methods of calculating the effective doses and equivalent doses resulting from the exposure of persons to ionising radiation (legifrance.gouv.fr).

These values depend on the incorporated radionuclide, its physical-chemical form, the contamination route (ingestion or inhalation), the type of person exposed (public, young workers up to 18 years of age or adult workers) and for a person of the public, in the same age categories.

To have all the dose coefficients per age category for the public and workers with all the physical-chemical forms, refer to the abovementioned Order of 16 November 2023.

• Engaged effective doses per unit of activity incorporated by ingestion, in sievert per becquerel, applicable to the public and to young workers aged up to 18 years (except daughter products of radon 222 and radon 220): see table 1.1 of the abovementioned Order of 16 November 2023 ;
• Engaged effective doses per unit of activity incorporated by inhalation of aerosols, in sievert per becquerel, applicable to the public and to young workers aged up to 18 years (except daughter products of radon 222 and radon 220): see table 1.2 of the abovementioned Order of 16 November 2023 ^[1] ;
• Engaged effective doses per unit of activity incorporated by inhalation of soluble or reactive gases and vapours, in sievert per becquerel, applicable to the public and to young workers aged up to 18 years: see table 2.1. of the abovementioned Order of 16 November 2023 ;
• Effective dose coefficients, in effective dose per day of exposure and per unit of activity concentration in the air, applicable to the public and to workers exposed to inert gases: see table 2.2.  of the abovementioned Order of 16 November 2023 ;
• Committed effective doses per unit of activity incorporated by ingestion, in sievert per becquerel, applicable to exposed workers: see table 3.1 of the abovementioned Order of 16 November 2023 ^[2] ;
• Committed effective doses per unit of activity incorporated by inhalation, in sievert per becquerel, applicable to exposed workers: see table 3.2 of the abovementioned Order of 16 November 2023 ^[3].
