This paper presents the activity of the Laboratory for Environmental and Personnel Dosimetry. This laboratory is a part of the Department of Life and Environmental Science from IFIN-HH. The laboratory has 4 units; each is dealing with a specific activity: -the dosimetric surveying unit which uses thermoluminiscent dosemeters for personnel (USD-TL). In USD-TL unit, the personnel monitoring is performed with thermoluminescent dosimetric system SD-TL which uses TL-detectors of LiF: Mg, Cu, and P with the measuring range 10 mu Sv - 100m Sv; -the unit for gammaspectrometrical analyses; -the unit for measuring the environmental radioactivity where the environmental samples (soil, surface and underground water, vegetal, aerosols and atmospheric sediments) are analyzed from the point of view of the gross alpha, beta and gamma activity. In the same unit, the environmental monitoring is performed also by TL system SDTM type with LiF: Mg, Cu, P detectors; -the unit for photodosimetrical survey. All these units are working according to the ISO/IEC: 17025:2005 requirements. They are recognized by the Romanian Nuclear Authority (The National Commission for the Control of the Nuclear Activity - CNCAN) and accredited by the RENAR (The National Accreditation Body). The R&D activity of the laboratory is focused on the personnel and environment dosimetry: -the development of survey methods for personnel using in TL dosimetry for the extremities; -the behavior of the TL detectors in ultra-low radiation background in the salt mines in Romania and intercomparisons of the TL-measuring systems.
