Summary

The German Federal Office for Radiation Protection (BfS) is the competent institution in Germany to protect man and the environment against ionising radiation. BfS runs a nation wide ambient dose rate monitoring network since over 30 years. The network technology is kept at state-of-the-art level through continuous development on detector technology. This includes long-time test series under various environmental conditions, international data and technology exchange. The probe to be installed at the Koldewey-Station is the standard BfS probe equipped with 2 Geiger-Müller tubes for high and low count rates. It measures automatically and continuously the environmental gamma dose rate in a wide range from some µSv/h up to 5 Sv/h. In general, it registers the radiation to get the terrestrial as well as the cosmic component of the gamma radiation. Moreover the probe measures the temperature and the air pressure in the probe housing for quality insurance, error detection and to estimate the cosmic component. The research project at the Koldewey-Station consists of three different aspects as outlined below. 1. Global monitoring of cosmic radiation component The cosmic radiation originating from the sun and from outer space is subject to a complex process of interaction with the earth’s magnetic field and atmosphere. Most of this radiation is attenuated and only a small fraction reaches the earth’s surface as ionizing radiation. At ground level, it contributes to the total measured ambient dose rate between 15%-50%. It is modulated by atmospheric pressure, the solar cycle and, occasionally, by solar flare events. Dose rate probes of similar response to cosmic radiation at different latitudes will help to understand the characteristics of the temporal variability of cosmic radiation and to better separate these effects from other environmental parameters. In case of current solar flare events the data will help to assess the impact on the dose rate monitoring network. To compare the data according to the German (PTB) reference standard, in a further step, a second reference probe (Reuter-Stokes (high pressure ionisation chamber) or Automess (plastic-szintillator) may be installed next. 2. Hardware test The BfS uses in-house developed hard- and software for dose rate monitoring. The systems are specially designed for reliable operation and robustness against adverse environmental conditions. The Koldewey-Station with temperatures of up to -25°C and mean temperatures of about -11°C in winter offers a good chance for the long term test of the probe hardware under extreme conditions. The relatively easy accessibility of the station, even in winter, makes the Koldewey-Station an ideal site. Prior to shipment, the probes will undergo a test in a BfS operated climate chamber to ensure that the probes are appropriate for commissioning at the site. 3. Intercomparison A similar station is run by NRPA at Longyearbyen (http://radnett.nrpa.no/?id
