The dose of record (E) refers to the [[effective dose assessed]] assessed by summing the measured personal dose equivalent H_p (10) and the committed effective dose retrospectively determined for the Reference Worker using results of individual monitoring of the worker and ICRP reference biokinetic and dosimetric computational models. Dose of record may be assessed using site-specific parameters of exposure, such as the absorption type of the material and the activity median aerodynamic diameter/activity median thermodynamic diameter of the inhaled aerosol but the parameters of the Reference Worker shall be fixed as defined by ICRP. Dose of record is assigned to the worker and required to be kept for purposes of reporting and retrospective demonstration of compliance with regulatory requirements.
