Abstract
A measuring head 1 which contains in a shielding housing 3 a measuring chamber 5 with a surface barrier-layer detector 9 is provided for measuring the noble gas activity concentration and the aerosol activity concentration. The gas whose activity concentration is to be measured is compressed and introduced into the measuring chamber 5. Due to the pressure increase of the gas, the volume of the measuring chamber 5 and, therefore, the weight of the shielding housing 3 can be reduced.
