Danish build automatic gamma-ray monitoring stations have been installed in the Baltic countries, Poland and Russia (Sct. Petersbourg region). The stations are designed for continously measure the gamma-radiation from the surroundings. The stations use the Windows NT 3.51 as operating system. Each ten minutes a gamma-ray spectrum is recorded and analysed by use of spectral components. This makes the stations capable of distinguish between natural radiation and artificial radiation. The stations are connected to main servers in each country and can call the servers if an alarm situation arises.New soft ware versions including new features have been installed. Also a servicepack 5 for windows NT 3.51 has been installed to make the system year 2000 proof. Simple maintainance of the stations was carried out during the visit.
