Helicopter-borne Radiometrics (HRD) Area 132 Glückstadt

BGR conducted within the project „Airborne geophysical surveys for mapping the shallow subsurface in Germany “ (D-AERO) airborne surveys at the German North Sea coast. The survey area Glueckstadt (2009/10) follows the course of the river Elbe from the city of Hamburg in the southeast to the mouth of the river in the northwest. The size of the area is about 1950 km². The area was surveyed with 62 flights totalling to 7782 line-km (214,369 survey points). The nominal separation of the 209 E-W lines and 18 N-S tie lines was 250 m and 2500 m, respectively. The maps display the total count, the (equivalent) content of potassium, uranium and thorium as well as the exposure rate at ground.
