The AMS 02 is an automatically working measuring system for counting radioactive aerosols through routinely measuring iodine, so that the non-natural radioactivity alpha-, beta- and gamma-radiation is counted. The system is equipped with a remote control unit, which allows for communication from and to the central unit at any time. The AMS 02 is a single filter system which enables different suction- and measuring programs. A further advantage is the possibility of testing the detectors through a calibration filter. Furthermore, under usual conditions, used filters can be re-used after decay of the natural radioactivity. Also, filters can be extracted to carry out high-precision analysis in corresponding laboratories. Under usual conditions, one suction-cycle takes 24 hours with one and the same filter. Measuring-evaluations are carried out at intervals of 5 min. If abnormities are measured and confirmed in the next two measuring-cycles (i.e. after three measuring-cycles), the device switches to intensive-mode. In the intensive-mode a new filter is inserted and sucted for 1 hour. The measuring evaluation permits an exact qualitative and quantitative statement concerning the alpha-, beta- and gamma-nuclides, the quality of which varies according to the detector type.
