Contents of potassium, uranium and thorium were measured in sixteen samples of stream sediments and in ten samples of dump material from the area around a small uranium deposit Zálesí near the town of Javorník using a laboratory gamma-ray spectrometer. All studied stream sediments show a low or moderately increased radioactivity (only 345 Bq.kg-1 as a maximum). In harmony with expectation the studied samples of dump material have increased radioactivity (970 Bq.kg-1 on average) due to high uranium contents (55 to 99 ppm eU).
