In June 2016 Nicole Klasen, Anja Zander and Franz Hartung (F2 project) visited David Sanderson at the Scottish Universities Environmental Research Centre (SUERC) in East Kilbride, Scotland, UK. They took the new portable NaI:Tl spectrometer and the BeOmax dosimetry system along for spectrometric and dose rate measurements in two special designed calibration blocks filled with granite and basalt, respectively. Firstly, they placed the new NaI:Tl detector for measurement. They will use the results to calibrate the detector for environmental dose rate determination in sediments. Secondly, they placed some OSL dosimeters of the BeOmax in the blocks. These dosimeters stood exposed to the radiation of the blocks for about a month. Recently, Franz Hartung went to East Kilbride again and retrieved them. Afterwards he discussed the results with David Sanderson and compared it to measurements and simulations that were previously performed at SUERC.
