These caves are situated in a Lugian region, in the area geologically called the Krkonoše-Jizera crystalline unit. Carbonate rocks occur in discontinuous streaks and lenses in this area. The lens in which the Bozkov caves were formed is 300 m in length and has a maximum width of about 150 m. The cave is permeated by calcareous and siliceous dolomite lenses from the Silurian age, surrounded by...

Show caves are special workplaces with increased health risk from radon exposure. Demänovská Cave of Liberty is one of the most visited show caves in Slovakia, situated at the northern side of the Low Tatras Mts. It is formed in the Middle Triassic Ramsau Dolomite and in carbonate rocks of Gutenstein Formation with Gutenstein limestone and dolomite, Annaberg limestone and organodetritic...

This study focuses on the measurement of radon concentrations in Veternica Cave, a karst cave system located at Medvednica Mountain, in the city of Zagreb – Croatia. This is the first time radon concentrations are being measured in Veternica Cave. Up to now the total of 6000 m of the cave has been explored, however only 380 m is available for visitors. These measurements involved systematic...

Uranium waste rock dumps contain residual uranium mineralization and, as a result, the entire uranium decay chain, notably the radioactive gas radon. Due to their high air permeability and large thermal capacity, these dumps naturally facilitate airflow through the stack effect. This thermally induced airflow leads to both spatial and temporal variations in radon gas exhalation at uranium...

One of the remnants in the areas of uranium ore mining, which are a potential source of radon, are waste rock dumps. Most of them are historically revitalized by natural means or targeted remediation carried out professionally. The aim of the remediation was and is to prevent the spread of radon to the surrounding settlements, which is very complicated due to the gaseous nature of radon. In...

Based on collaboration between the staff of the SÚJCHBO, v.v.i., DIAMO s.p., SÚRO, v.v.i. and FJFI ČVUT measurement campaigns were conducted in the vicinity of the uranium waste rock dumps in the Příbram region. These measurements confirmed high radon activity concentrations in the ambient air at levels exceeding several kBq.m-3. The measurements also verified annual and daily variations of...

Kamila Johnová (SÚRO, v.v.i.)12/09/2024, 11:00Health effects of radonOral presentation
Radon from soil gas is generally recognised as the main cause of increased radon concentration in buildings. It is also widely understood that underground water or building material might be the secondary cause of radon problems indoors. Putting those well-known sources aside, we focused on a rather non-traditional source of indoor radon. We investigated the possibility that radon...

The main internal source of radon (not only in living spaces) is the geological subsoil; it can also be building material or water. These sources are already relatively well captured and legislative mechanisms have been established to monitor and evaluate their health impact over the long term, and eliminate them in case of exceeding the guideline values. However, it is a question of what part...
