Great video. Radon, if emanated from the soil or construction material, will accumulate under the slab and find its way to cracks or gaps in the concrete, so I was impressed to see what a good job you did sealing around the concrete/pipe penetrations. That's where it will get in IF its present. In 1983, we built two walk-in sized radon calibration chambers for development, calibration and testing of radon detectors. We simply bored a hole on the massive concrete slab that our building was built on, scooped out some dirt to make a larger hole and applied a negative pressure from a low flow radon mitigation fan and we a perfect natural radon/thoron source.
Yes you are right, exactly all pipes, lightning rods etc. has to be perfectly sealed with molten asphalt to achieve radon proof layer. For sure in future when walls with roof will be done I´m going to apply asphalt sheets all over floor in 2 layers with focus to really melt all joints together.
žiadne hajdroizolejšn ani hajdroinsulejšn v angličtine nie je ako preklad hydroizolácie stavby, bude sa to zle hľadať zahraničným sledovateľom. Ten radónový index tam musí byť naozaj vysoký pri tých opatreniach okolo prestupov.
Dík za postreh ;) ... opatrenia proti radonu su standardom pri novostavbach, ono sa tomu neda vyhnut nakolko je to povinnostou. Podla mnozstva radonu v danej lokalite sa volia rôzne opatrenia. Tie ktoré robím ja sú ešte úplne v pohode nakolko je hydroizolácia a radonova izolacia v jednom. Ak je niekto v lokalite s vysokým radonovym rizikom tak musí spraviť odvetranie zásypu pod dekou a vyústenie až nad strechu aby sa to odvetrávalo komínovým efektom. To stavebníctvo je veru riadna "sranda" :D

Very nice work! :)
