As part of a survey on concentrations radon, thoron and their decay products in different indoor environments the Balkan region involving international collaboration, measurements were performed 43 schools from 5 municipalities Republic Macedonia. The time-integrated radon gas (CRn CTn) measured by CR-39 (placed chambers with diffusion barriers), whereas equilibrium equivalent (EERC EETC) using direct radon-thoron progeny sensors consisting LR-115 nuclear track detectors. detectors deployed...
Radon accumulation in indoor environments poses a significant public health concern, especially educational institutions, where children are particularly vulnerable. This study investigates radon activity concentrations (IRAC) 198 institutions and 266 houses from Cluj-Napoca, Romania, analyzing total of 1440 rooms. levels were assessed using CR-39 track detectors, with measurements conducted over three twelve-month periods for residential buildings, respectively. Preliminary results reveal...
Abstract The present study aims to identify novel means of increasing the accuracy estimated annual indoor radon concentration based on application temporal correction factors short-term measurements. necessity accurate and more reliable is in high demand, age speed. In this sense, measurements were continuously carried out, using a newly developed smart device accompanied by CR-39 detectors, for one full year, 71 residential buildings located 5 Romanian cities. coefficient variation...

In the present study, measurements of radon were carried out using LUK-VR system based on gas with Lucas cells. The radium concentration in water was determined, same device, immediately after established equilibrium radium. results presented here are from a survey N-W region Transylvania (Romania) which investigated concentrations natural (spring, well and surface) drinking (tap) waters. showed within range 0.4-187.3 Bq l(-1) an average value 15.9 whereas varied between 0.05 0.825 0.087 for...
Seasonal variations of the radon and radium activity concentrations in karstic water sources originating formations were investigated as part a premiere systematic survey conducted Romania. A database including total 228 drinking samples collected from 30 distinct adjacent to rural communities was compiled. The for all seasons, assessed based on solid scintillation, ranged 2.1 19.7 Bq/L 0.6 3.0 Bq/L, respectively. Overall, detected contents did not exceed radioprotection standards...
The purpose of this article is the assessment energy efficiency and indoor air quality for a single-family house located in Cluj-Napoca County, Romania. studied meant to be an energy-efficient building with thermal insulation, low U-value windows, high boiler. Increasing leads lower quality, due lack natural ventilation. As experimental campaign regarding revealed, there need find balance between consumption air. To achieve superior proposed mitigation systems (decentralized mechanical...
The geogenic radon potential is primarily controlled by the geological characteristics of site, such as rock type and structural elements, well permeability soil. Depending on scope survey, can be mapped based measurements conducted in field at various resolutions. Detailed surveys are generally labour-intensive time-consuming. Therefore, a balance should reached between desired level precision required amount effort, delivering best results with least number resources. international...
In many countries, caves can pose an economic interest for the authorities and stakeholders. The development of a show cave requires, apart from conservation issues, to ensure human safety by minimising exposure radon personnel visitors. Radon levels vary widely cave, being directly correlated with different internal external factors. It is therefore important monitor before establishing number required, so that they are not exposed health-threatening radiation. A long-term survey was...
The purpose of the article is to evaluate annual effective dose for 80 women divided into two samples; one sample located in former uranium Băiţa-Ştei area, hereinafter referred as case sample, respectively a control same county, but exposed most cases indoor radon activity concentrations <300 Bq m-3. In this regard, homemade 'RaThoGamma' kit was used, which contained thermoluminescent dosimeters, CR-39 track detector (RSKS) concentration, detectors (Radtrak2®/ Radtrak2T®) and thoron well...
Mapping the geogenic radon potential in Buzău County is part of a research project aiming to apply for sustainable development and economic growth following principles geoconservation order support 'Buzău Land' UNESCO Geopark initiative. The mapping will be used as an overview planning purposes. main geological formations studied area were identified Cretaceous Paleogene flysch, included thin-skinned nappes pile consisting alternating sandstones, marls, clays and, subordinately,...
Schools are a category of public buildings with high radon exposure risk, due to their occupancy factor. In Romania, the elaboration methodology for measurements in schools is necessity imposed both by European legislation and relatively percentage (about 10%) mapped territory potential increased risk action ionizing radiation emitted radon. order optimize design national survey aimed evaluate children Romanian schools, we conducted pilot study two Cluj-Napoca, following screening carried...
Measurements have been carried out using four types of passive detectors in the most popular show caves Romania. Three (RSKS, RadTrak and CD) were used for radon measurements two (Raduet thoron measurement. Activity concentrations air measured same locations seasons, autumn winter. Measured values different varied between below detection limit (5 Bq m-3) 4024 m-3 from 10 to 583 thoron. The results indicate a very good correlation RSKS (r = 0.96). significant difference with (RSKS was higher...
Abstract A recent challenge in research dedicated to residential exposure radon comes from the growing number of houses retrofitted reduce energy consumption. Efficiently insulated buildings and modern architectural solutions can lead accumulation high levels indoor pollutants. systematic analysis was conducted a complex (consisting six houses) order assess annual concentration evaluate intensity relationships with various factors, such as indoor-outdoor temperature differences, wind speed...
