Abstract
Buzău Land aspiring Geopark is a 1036km2 territory located in Romania, at the Carpathians Bend, in the close proximity of the Vrancea seismogenic area. Our work deals with natural hazards and risk in the aspiring Geopark territory. One of the hazards approached, which is the subject of this paper, refers to the exposure to natural radiation of inhabitants and visitors alike. Our work is still in progress, and we shall present its development so far. The measured values for radioactivity dose vary between 7.82 nSv/h and 56.83 nSv/h. Th levels vary between 1.38 ppm and 11.69 ppm, U levels vary between 0.31 ppm and 4.5 ppm and K levels vary between 0.32% and 2.12%. So far it seems that the natural radioactivity dose does not pose risk towards the inhabitants of Buzău Land Geopark or to its visitors, as the dose values are about 10 times smaller than the world average. We shall continue our measurements in order to optimally cover the entire territory and all lithological units, to have a comprehensive overview of the distribution of background radioactivity levels.
