[en] The main task of the team was to create a fallout map of ¹³⁷Cs in a specified area in Padasjoki Auttoinen village. The team used an MI-8 helicopter of the Finnish Air Force. The team had an HPGe system (relative efficiency 70%) to measure nuclide specific ground contamination level. For navigation the team took advantage of the DGPS service provided by Finnish Broadcasting company utilizing the RDS-channel to get position accuracy within 2 meters. The correction signal is reachable nationwide on the FM transmitter network. The system produced a distribution map for ⁴⁰K and fallout maps for ^134,137Cs using a Micro Station Program with TerraModeler application. The maximum measured ¹³⁷Cs ground contamination exceeded 130-140 kBqm^-2. (au)
