The Swedish Radiation Safety Authority, SSM, will purchase a new system for mobile dose rate monitoring. The system shall include 30 mobile dose rate instruments that can be deployed quickly for detailed mapping of dose rates from radioactive fallout around Swedish nuclear power plants in the early/intermediate phase after a nuclear emergency.
A mobile dose rate instruments shall, when deployed, continuously monitor the dose rates, e.g. along roads directly from a moving car. Dose rates shallbe measured in short cyclic intervals and stored with GPS-positions. The main detector in the instrument shallbe a small spectroscopic NaI(Tl)-detector. Dose rates shallbe calculated from the NaI(Tl)-spectra. For use in high dose rates there shallbe an additional GM-tube.
