Souhrn měření dceřinných produktů rozpadu radonu a aerosolových částic v Bozkovských dolomitových jeskyních
Thinová, L. ; Berka, Z. ; Brandejsová, E. ; Ždímal, Vladimír ; Milka, D.
To define the calculation of the effective dose in caves, the following measurements were carried out: continual radon measurement, regular radon and daughter measurement through the sampling procedure to specify propoprtion of radon daughters, regular indoor air flow measurement to study the location of radon supply and its transfer among individual parts of the cave.
Rozdělení velikostí aerosolových částic v budovách a jeskyních a jeho vliv na určení dávky spojené s radonem

This paper summarized results of aerosol particles sizes spectra evaluation which has been measured directly in the Bozkov cave. These spectra are compared with the ones for residental areas and the radon-to-dose convertion factor is disscused. The correction factor (so called "caves factor") value is discussed too.
První výpočty efektivní dávky z měření dceřinných produktů rozpadu radonu a aerosolových částic v jeskyních

The result from continual radon activity measurement, immediate radon daughter and radon activity sampling (one per month), air flow measurement, and aerosol particle size distribution determination have been taken into account of the effective dose of the permanent guides in caves. All data obtained by the carried out measurements and calculations published by J. Porstendörfer were used for more exact determination of an effective doses from radon and daughters inhalation for guides in the Bozkov cave.
