Promieniotwórczość gleb Ojcowskiego Parku Narodowego

This work presents the results of the determination of caesium 137Cs deposition and concentrations of potassium ⁴⁰K, radium ²²⁶Ra and actinium ²²⁸Ac in soil samples collected in Ojców National Park by CLOR. Concentration measurements were taken by gamma radiation spectrometry using a spectrometric track with a coaxial HPGe detector. Exposure of people to ionizing radiation in Ojców National Park was estimated on the basis of natural radionuclide concentrations in soil samples. In addition, the obtained determinations of caesium deposition and concentrations of natural radionuclides in the soil were compared with the results of research conducted by CLOR in several other National Parks in our country and also for Poland and Małopolskie Voivodeship (CLOR radiological monitoring carried out cyclically since 1988, study for the Chief Inspectorate of Environmental Protection).
