    "abstract": "High-resolution gamma-ray spectrometry was exploited to determine naturally\noccurring thorium (Th), uranium (U) and potassium (K) elemental concentrations\nin the whole area covered by the Troodos Ophiolite Complex of Cyprus. For that\npurpose, a total of 59 samples from surface soils and 10 from the main rock\nformations of the region of interest were analysed. Elemental concentrations\nwere determined for Th (range from 2.5x10^-3 ppm to 2.0 ppm), U (from 8.1x10^-4\nppm to 0.6 ppm), and K (from 1.3x10^-4 % to 1.0 %). The average values (A.M +-\nS.D.) derived are (0.24 +- 0.34) ppm, (0.10 +- 0.10) ppm and (0.21 +- 0.24) %,\nfor Th, U, and K, respectively, in the soils, and (0.52 +- 0.17) ppm, (0.17 +-\n0.11) ppm and (0.49 +- 0.87) % in the rocks. From these values, a radioactivity\n(radioelement) loss of nearly 50% is estimated in the underlying surface soils\ndue to bleaching and eluviation during weathering of the rocks. The measured\nTh/U ratio exhibits values between 2 and 4, whereas the K/Th ratio is highly\nvariable ranging between 1.5x10^3 and 3.0x10^4.",
