U and Th isotopic composition have been proven to be a valuable tool in environmental science, oceanography, hydrology, geology, nuclear forensics, and science-based archaeology. These applications require simultaneous detection of both minor and major isotopes at high accuracy. Often, the amount of sample or concentration of U and Th are …

Adaptation to altitude can enhance performance if the hypoxic dose and the frequency of the exposures are appropriate. While many hypoxic training modalities exist, the protocols utilizing short intermittent hypoxic exposures are gaining popularity. However, the effects of such novel hypoxic protocols on athletic performance are unclear. The aim of …

The aim of the present thesis was to examine the effect of acute and long-term normobaric hyperoxic exposure on selected haemodynamic and haematological responses during resting and exercise conditions in healthy aerobically well-trained males. This purpose was evaluated in four separate studies, and each of them had a specific aim …

Radon and its progeny play an important role contributing to the dose of radiation which a person receives from all natural sources of ionizing radiation. This is one of the reasons why this problem has been of great interest, as a result of which an increased number of scientific works …

A study of the migration of critical radionuclide in the area of the former uranium mine of Žirovski vrh in Slovenia was performed. Critical natural radionuclides are defined as the long-lived natural radionuclides from the uranium-radium decay chain, which are 238U, 234U, 230Th, 226Ra, 210Pb and 210Po. In the area …
