Researchers around the world had already established that radon and thoron are a hazard to the human health. Different techniques and methods are applied in order to measure them as accurately as possible. In Romania, most measurements earlier conducted were focused on using grab-sampling measurements to establish the two gasses decay progeny activity(More)
Measurements have been carried out using four types of passive detectors in four of the most popular show caves in Romania. Three types of detectors (RSKS, RadTrak and CD) were used for radon measurements and two (Raduet and CD) for thoron measurement. Activity concentrations in air were measured in the same locations for two seasons, autumn and winter.(More)
A comprehensive radon survey has been carried out in seven caves located in the western half of Romania's most significant karst regions. Touristic and non-touristic caves were investigated with the aim to provide a reliable distribution of their radon levels and evaluate the occupational exposure and associated effective doses. Radon gas concentrations(More)
A new thoron/radon survey was started in the north-western part of Romania, covering three counties, using discriminative detectors (RADUET). All detectors were deployed throughout 3 months, covering the spring period. The measured radon and thoron concentration ranged from 31 to 414 Bq m(-3) and from below the detection limit to 235 Bq m(-3), respectively.(More)
In the present study, the measurements of radon were carried out using the LUK-VR system based on radon gas measurements with Lucas cells. The radium concentration in water was determined, with the same device, immediately after was established the radon equilibrium with radium. The results presented here are from a survey carried out in the N-W region of(More)
A comprehensive radon survey has been carried out in Băiţa radon-prone area, Transylvania, Romania, in 4 localities (Băiţa, Nucet, Fînaţe, and Cîmpani) situated in the vicinity of former Romanian uranium mines. Indoor radon concentrations have been measured in 1128 ground floor rooms and cellars of 303 family houses by using CR-39 diffusion type radon(More)
Mapping the geogenic radon potential in Buzău County is part of a research project aiming to apply research for sustainable development and economic growth following the principles of geoconservation in order to support the 'Buzău Land' UNESCO Geopark initiative. The mapping of geogenic radon will be used as an overview for planning purposes. The main(More)

The influence of high geogenic carbon dioxide concentrations on monitoring devices might present a significant challenge to the measurement of radon concentrations in environments with a high level of carbon dioxide concentration such as volcano sites, mofettes, caves, etc. In this study, the influence of carbon dioxide concentration on several different(More)
