Estimating the Radioactive Heat Production of a Granitic Rock in the University of A Coruña (Galicia, Northwest Spain) by Gamma-ray Spectrometry

Geothermal energy is a form of renewable with long tradition in European countries, although it scarcely used Spain. One the reasons for this poorly studied geothermal potential Spanish territory. In recent years, data published on terrestrial gamma radiation and geochemistry radioisotopes rocks have suggested that radiogenic heat production (RHP) some areas Spain high. work, we assessed RHP by analysing U, Th, K contents underlying most important campus University A Coruña (northwest Spain), using situ handheld gamma-ray spectrometry (GRS) X-ray fluorescence (XRF). Our results provide good fit radioisotope unexpectedly high RHP, compared average observed similar (granodiorite). These reveal GRS very reliable tool studying rock surfaces, can be area (i.e., campus, but also city Coruña, as built same rock) central heating buildings ground-source pumps (GSHPs).
