This International Standard specifies the minimum requirements for the design of professionalprogrammes to monitor workers exposed to uranium compounds. It establishes principles for thedevelopment of compatible goals and requirements for monitoring programmes and dose assessment forworkers occupationally exposed to internal contamination. It establishes procedures and assumptionsfor risk analysis, monitoring programmes and the standardised interpretation of monitoring data inorder to achieve acceptable levels of reliability for uranium and its compounds. It sets limits for theapplicability of the procedures in respect to dose levels above which more sophisticated methods haveto be applied.Uranium is both radiologically and chemically toxic. Hence, the scientific bases of current occupationalexposure standards are reviewed in addition to radiation exposure limits. This International Standardaddresses those circumstances when exposure could be constrained by either radiological or chemicaltoxicity concerns.This International Standard addresses, for uranium and its compounds, the following items:a) purposes of monitoring and monitoring programmes;b) description of the different categories of monitoring programmes;c) quantitative criteria for conducting monitoring programmes;d) suitable methods for monitoring and criteria for their selection;e) information that has to be collected for the design of a monitoring programme;f) general requirements for monitoring programmes (e.g. detection limits, tolerated uncertainties);g) frequencies of measurements;h) procedures for dose assessment based on reference levels for routine and special monitoringprogrammes;i) assumptions for the selection of dose-critical parameter values;j) criteria for determining the significance of monitoring results;k) interpretation of workplace monitoring results;l) uncertainties arising from dose assessment and interpretation of bioassays data;m) reporting/documentation;n) quality assurance;o) record keeping requirements.It is not applicable to the following items:a) monitoring of exposure due to uranium progeny, including radon;b) detailed descriptions of measuring methods and techniques for uranium;c) dosimetry for litigation cases;d) modelling for the improvement of internal dosimetry;e) potential influence of counter-measures (e.g. administration of chelating agents);f) investigation of the causes or implications of an exposure;g) dosimetry for ingestion exposures and for contaminated wounds.
