Comprehensive radon concentration measurements in caves located in the area of Mecsek mountains

摘要: Radon concentration has been investigated in nine caves of the Mecsek Mountains, Hungary. Apart from radon concentra­tion, underground temperature and pressure were detected by DATAQUA monitoring devices. Our primary aim was to gain information about boththe levels convectional systems these order study characteristics researcharea. In addition, we intended detect any differences between either on basis previous measurements or account their topo-mor­phological location. Data comprehensively analyzed relation surface atmospheric pressure. The collected data showed that located researcharea have particularly highradon concentrations. highest values measured valley floor-positioned whereas lowest ones hilltop-positioned caves. four cases air convection studied differed what would indicated topo-morphological loca­tion. our summarize laws uniqueness investigated.
