Activity concentration of natural radioactivity (238U, 234U, 226Ra, 210Po) and 137Cs in organs and tissue of wild European perch from lake Fiolen and lake Fysingen. The activity is showed in Bq/kg in fresh weight.

The samples of European perch (Perca fluviatilis) consisted of 39 individuals caught in Lake Fiolen and 95 individuals caught in Lake Fysingen during 2020. The sample collection was performed by the Swedish Museum of Natural History and the samples were provided as a loan from their sample bank Environmental Specimen Bank.

The data consists of the mean measurements of the radioactive elements in different anatomical regions of the perch samples. Cesium-137 content could not be measured in the fins of the samples from Lake Fysingen, resulting in a missing value.

The data is available as an Excel file and as a semicolon-separated .csv.
