Continuous measurements of radon and radon progeny in various public places

The exposure to radon in buildings open the public and at workplaces depends on many factors, for example, forms of utilization, construction conditions, time exposure, heating, ventilation etc. To evaluate different working environments, continuous simultaneous measurements (CRn), equilibrium equivalent (EEC), potential alpha energy (PAEC) concentrations 24 hours were performed using AlphaE CRn DOSEman PRO from SARAD GmbH EEC PAEC measurements. study considered three locations radon-rich spa Narechen, Asenovgrad, an old mine turned museum town Pernik. A comparison was made between average values relating all-day only when completed. increases during as well bath spa, while it decreases spa’s treatment room. On other hand, are increasing all locations. due hours, which integrated into long-term can cause underestimated exposures reach environment.
