In connection with prospecting for uranium ores in northern Sweden, a peat bog, situated 4.5 km NW of Masugnsbyn, Norrbotten, Sweden and showing a remarkable content of uranium, was discovered. Closer investigation of several samples of the peat indicated that the comparatively high content of uranium and radon was connected with the occurrence of radioactive springs in the region. It was found that four different kinds of water were responsible for the supply of radioactive material to the peat, viz: ground water, surface water, spring water, and ground water emanating from fractured rock. The spring water--probably a mixture of ground water and water from the fractured rock-contains uranium to the extent of micrograms per liter. The pH is about 7. The uranium content of the water system deriving from the fractured rock is about 200 to 300 micrograms per liter. The maximum radon content is about 3000 emans. The pH is)7 and the specific condnctivity about 150 x 10>s-/sup > /m>s-/sup > /cm>s-/sup >./he radioactive peat is charact erized by extremely low gamma radioactivity which may be due to the recent emplacement of uranium by spring waters. It is suggested that the peat in question has served as a "collector" for uranium, rare earth metals etc., since the pH condition--pH about 7--was favorable to the settling of these elements. The uradium enrichment seems to be due to a transport of Na, Mg, and Ca bicarbonates emanating from dolomite deposits or pegaiatitic granite dikes in the vicinity of the peat, the bicarbonate waters serving as carriers of the uranium.
