The document deals with gamma radiation measuring places for the measurement of radioactive materials with low specific activity with energies between 40 keV to 2 MeV and with detector systems being hided in a shielding chamber. The document deals with standard systems for routine applications with measuring times of 1 hour and a limit of detection of about 1 Bq/kg.
