In Latvia the caesium-137 contamination from the Chernobyl accident and from the nuclear weapon tests in the 1960´es is very low. Conventional techniques for extracting information from the measured spectra cannot be used here. Therefore a new, sensitive technique - the pseudo concentration method - was developed, and maps could be produced for several regions in Latvia measured with airborne gamma-ray spectrometry in 1995.
