Indoor Aerosol Behaviour
Smolík, Jiří ; Moravec, Pavel ; Schwarz, Jaroslav ; Ždímal, Vladimír ; Dahlin, E. ; Drossinos, Y. ; Lapti, M. ; Lazaridis, M.
The results showed that the indoor aerosol concentrations depend beside outdoor concentrations and room geometry especially on ventilation and deposition rates. At higher ventilation rates the indoor aerosol concentrations approached the outdoor ones. This was observed for the accumulation mode particles.
Atmospheric Aerosol Composition Measured on Crete
Smolík, Jiří ; Ždímal, Vladimír ; Schwarz, Jaroslav ; Havránek, Vladimír ; Eleftheriadis, K. ; Lazaridis, M. ; Mihalopoulos, N.
A Berner low pressure impactor was used to collect size-segregated aerosol samples at Finokalia station located on the north-eastern coast of Crete Island, Greece during July 2000 and January 2001. Several samples were also collected during the summer campaign aboard of research vessel 'AEGAIEO' in the Aegean Sea.
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
Berka, Z. ; Thinová, L. ; Brandejsová, E. ; Ždímal, Vladimír ; Froňka, A. ; Milka, D.
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
Thinová, L. ; Berka, Z. ; Brandejsová, E. ; Ždímal, Vladimír
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.
Porovnání dvou metod určování rychlosti nukleace v difúzní mlžné komoře
Ždímal, Vladimír ; Brus, David ; Uchtmann, H.
It was the aim of this work to perform a comparative nucleatuon experiment i which the rate was determined by both approaches at the same time.
The Effect of Various Activities on Indoor Particle Concentrations
Smolík, Jiří ; Ždímal, Vladimír ; Schwarz, Jaroslav
The contribution describes experimental study of effect of various activities at home (ccoking, venting, smoking, burning of candles or incentives) on indoor particle concentrations. Dynamics of individual size fractions in size range 3-20.000 nm is studied using system of instruments NanoSMPS, SMPS, and APS.
Robustní odhad rozdělení velikostí částic atmosférických aerosolů pomocí gnostické teorie
Wagner, Zdeněk ; Ždímal, Vladimír ; Smolík, Jiří
A new approach using gnostic theory of uncertain data is applied to analysis of particle size distribution in atmospheric aerosols. The properties of the gnostic kernel, derived from theory, is demonstrated. Enhancement of gnostic theory, which allows robust kernel estimation of the distribution function as well as the bounds of the data support, is explained.
