One year of x-ray dosimetry in a high voltage laboratory

Abstract

Reports of x-rays detection, produced by impulsive voltages in ordinary high voltage laboratories, can be found in the literature. These high voltages are very often to occur in the daily work of the laboratories around the world. This paper presents measurement results of x-ray dosimetry using thermo luminescent detectors (TLD) along 12 months of regular working in the High Voltage Laboratory of Institute of Energy and Environment (IEE) of the University of São Paulo (USP). Experimental tests applying high voltage impulses and placing TLDs in the vicinities of the electrode were performed and dosimetries in these conditions are also presented.
