Since 1992 in Bulgaria operates an automated system for permanent control of the radiation gamma background (NASPCRGB). The system has been modernized by means of a European program during its last operation period and is connected with EURDEP – the European System for Exchange of Radiological Data of the European Commission. The operation of the System and its management are assigned to the Executive Environment Agency of the Ministry of Environment and Water Resources. In the present article we have shown the structure of the National Automated System for permanent control of the radiation gamma background (NASPCRGB) and its functions. KEYWORDS: radiation background, control, management, probe, data 1. Introduction Nichev, 2016). Later it was found out, that After the radioactivity was discovered the space radiation comprises two in the beginning of the century the scientists components: primary radiation – of galactic had considered, that only the soil and the origin, penetrating into the atmosphere, and rocks were a source of radiation into the secondary space radiation – originating atmosphere. Yet very soon it had been from the reaction of the cosmic rays with discovered that when the altitude increased the nuclei of the air elements, with the (in experiments with balloons), also the space dust, precipitating on the planet and radioactive radiations increased, resulting others.
