The method of radiation risk assessment based on physico-geographical regionalisation: a case study of Carpathians, Poland.

Radiological assessment of the environment in expansive territories poses significant challenges due to the complexity of spatial and environmental variables. The aim of this study was to use and present the advantages of a physico-geographical regionalisation methodology to improve the precision and effectiveness of radiological assessments in large areas. The study area was a region of the Polish Carpathian mountains with a territory of 19,600 km.

A Geological Context in Radiation Risk Assessment to the Public.

The work aimed to show the applicability of geological studies to the investigation of radiation risk assessment due to the presence of naturally occurring radionuclides of terrestrial origin in the soil. Soil samples were taken from a Tatra Mountains area for which geological maps were available. The concentration of selected radionuclides incl.

Sedimentary conditions based on the vertical distribution of radionuclides in small dystrophic lakes: a case study of Toporowe Stawy Lakes (Tatra Mountains, Poland).

The aim of this work was to prove the use of radionuclides deposited in sediment core taken from an overgrowing dystrophic lakes surrounded by marsh-peat vegetation to estimate sedimentary conditions. Sediment core samples were taken from the Toporowe Stawy Lakes (Niżni (TSN) and Wyżni (TSW); Tatra Mountains). The sampling was done using a Limnos corer.

Origin and behavior of radionuclides in sediment core: a case study of the sediments collected from man-made reservoirs located in the past mining region in Central Slovakia.

The analyzed sediments were taken from the man-made reservoirs (Velka Richnava, Rozgrund and Vindsachta) located in an area intensively mined for polymetallic ores since the end of the eleventh century (Banska Stiavnica region, Central Europe). The aims of this study were to determine the radioactivity of natural (Ra, Th, Pb) and artificial (Cs and Am) radionuclides, compare the radionuclides' distribution, and indicate the correlation of radioisotopes and their origin related to sediment properties. Two analytical techniques were used.

Concentrations of Cs and K radionuclides and some heavy metals in soil samples from the eastern part of the Main Ridge of the Flysch Carpathians.

The aim of the study is to present the results of determination of radioactivity of artificial Cs and natural K and certain heavy metals in soil samples collected from the eastern part of the Main Ridge of Carpathians, including the Beskid Niski Mts and the Bieszczady Mts. The evaluation of level of radionuclides was based on the bulk density analysis of the soil. A valuable finding of the study was a good linear correlation between the level of Cs concentration and bulk density of the soil as well as an inverse correlation between radioactivity of natural K and tested soil density.
