The system of personal monitoring and the evaluation of occupational exposure in the Czech Republic.

Abstract

New legislation concerning radiation protection, which was effective in the Czech Republic from 1997, followed from the recommendations of ICRP Publication 60 and the IAEA BSS, and included all new basic principles for the protection of radiation workers given in these documents. The requirements for the personal monitoring of category A workers and the recognition of the capacity of dosimetry services were identified as being very significant for radiation practice, and will be licensed by the State Office for Nuclear Safety (SONS). The license application will include the methodology of effective dose evaluation, the description of QA and QC of the service, the system of customer communication and dose recording and reporting. In accordance with legislation requirements, the licensee is obliged to report the personal and dosimetry data of category A radiation workers to SONS. For the purpose of data collection, SONS is developing the central registration system of occupational radiation exposure (CROE). Personal monitoring is managed for about 20,000 workers in 1500 workplaces. The paper describes in detail all current aspects of external monitoring of workers in the Czech Republic.
