Helicopter-borne Radiometrics (HRD) Area 111 Ellerbeker Rinne

BGR conducted within the EU Interreg-IIIb project "Ancient groundwater reservoirs in buried valleys" (BurVal) an airborne survey in the region of the Ellerbeker Rinne in cooperation with the State Geological Surveys of Schleswig-Holstein (LANU) and Hamburg (BSU). The survey area Ellerbeker Rinne (2005/06) is located to the northwest of the Hanseatic City of Hamburg and is about bounded by the motorway A23 to the west and by Bad Bramstedt to the northeast. The size of the area is about 280 km². The area was surveyed with 7 flights totalling to 899 line-km (23,628 survey points). The nominal separation of the 99 ENE-WSW lines and 6 NNW-SSE tie lines was 400/600 m and 2000 m, respectively. The maps display the total count, the (equivalent) content of potassium, uranium and thorium as well as the exposure rate at ground.本研究在欧盟Interreg-IIIb项目“埋藏谷中的古地下水储层”（BurVal）框架内开展，由BGR与石勒苏益格-荷尔斯泰因州地质调查局（LANU）、汉堡州地质调查局（BSU）合作，在埃勒贝克谷（Ellerbeker Rinne）区域实施航空测量。埃勒贝克谷测量区（2005/2006年）位于汉萨城市汉堡西北部，其范围大致以A23高速公路为西界、巴特布拉姆施泰特为东北界，总面积约280平方千米。本次测量共计完成7架次飞行，总测线长度达899千米，共覆盖23628个测量点。其中99条ENE-WSW向主测线与6条NNW-SSE向联络测线的标称间距分别为400/600米与2000米。所展示地图包含钾、铀、钍的总计数与（等效）含量，以及地面辐射暴露率。
