THE GERMAN REGULATORY SYSTEM OF MONITORING WORKER’S DOSEP.HillForschungszentrum Jülich GmbH, S, 52425 Jülich, GermanyIntroduction: The occupational safety of workers is generally the competence of the single German states. All matters of radiation protection in the professional environment are governed by the national nuclear law. Relating regulations form the statuatory framework for dose monitoring. Federal government and states interact in the implementation. A National Dose Registry has been established. Several bodies and institutions are involved in practical aspects of radiation protection.Radiation Protection Ordinance: The Radiation Protection Ordinance is the main statutuary document and regulates the handling of sources of radiation as well as exposure, also including NORM-Materials and medical research and applications. Several paragraphs are dedicated to dose limits and dose monitoring. Competent external/internal monitoring bodies ensure the measurement and evaluation of dose. They have to be notified by appropriate state authorities.Guidelines on dose monitoring: The two parts of the main guideline are dedicated to external and internal monitoring, rsp. The guidelines contain detailed rules to implement the Radiation Protection Ordinance. Under which circumstances is dose monitoring mandatory? How has dose monitoring to be performed. How are doses calculated? Which documentation is required? These and other practical topics are covered. NORM activities are subject of a separate guideline.Competent external/internal monitoring bodies: They are subject to notification by the authorities of the individual German states. Presently there are 4 notified laboratories for monitoring external dose and one laboratory specialised in Radon measurements. For internal monitoring there are xx notified in-vivo laboratorise, yy notified in- vitro monitoring laboratories and zz notified for both in-vivo and in-vitro. A Competent Internal Monitoring Body is described in another contribution to this conference (CIMB-J).Federal Office of Radiation Protection: Provides advice and some mandatory intercomparisons. Operates the National Dose Registry. Professional radiation workers and their individual doses are registrated in the registry. The registry ensures that doses resulting from different employments during a carreer are all included in checking the compliance with dose limits.Federal Radiation Protection Commission: This commission is the advisory board to the national government in matters of Radiation Protection. It consists of individual members called to serve honorarily. It gives recommendations on the different aspects of radiation protection. Relevant to dose monitoring is e.g. its recommendation on how to calculate body dose from external sources.Joint committee of federal states and national government: Coordinates matters of joint interest. It approves e.g. the dosemeters (types) to be used in official external dose monitoring. ‘Physikalische Bundesanstalt’: This is the national state metrological institute. It type tests dosemeters and approves their fit-for-purposeness. It organizes annual intercomparisons for dosemeters.
