Радиация из пустоты: Смертельное дыхание Пашийской пещеры
An experiment in the depths of the Pashiyskaya Cave: measuring the activity of radioactive radon gas in an unusual way. I use a filter mask to collect the daughter products of decay. The video shows before and after dose rate measurements, spectrometric analysis of the mask, and calculation of the volumetric activity of radon in the air of the cave.
