    Radon Dose Determination for Cave Guides in Czech Republic

  • Original language description

    The enhancement of personal dosimetry for underground work places includes a study of the given questions, from those points of view in each cave: continual radon measurement; regular measurements of radon and its daughters to estimate the equilibrium factor and the presence of free 218Po; regular indoor air flow measurements to study the location of the radon supply and its transfer among individual areas of the cave; natural radioactive element content evaluation in subsoil and in water inside/outside, a study of the radon sources in the cave; determination of the free fraction from continual unattached and attached fraction measurement (grid and filter); thoron measurement. Most of the results show the equilibrium factor around F=0.2-0.7 and the unattached fraction around 2%-30%.

    Výpočet dávky od radonu pro průvodce v jeskyních v ČR

  • Czech description

    Pro výpočet dávek pro průvodce v jeskyních ČR byla provedena řada měření: směry proudění; stanovení volné a vázané frakce; kontinuální měření OAR; krátkodobé produkty přeměny radonu a faktor nerovnováhy; gamaspektrometrické stanovení radionuklidů v přítomných horninách atd. měření ukazují na F=0,2 - 0,7 a podíl volné frakce 2%-30%.
