The accurate and continuous monitoring of radon concentration in indoor spaces, such as educational and work environments, is crucial for public health and safety. This study, part of a PhD thesis on statistical and computational analyses of radon levels, addresses a critical challenge in the radiation protection community: the fragmentation of data and a lack of standardized collaboration...

Introduction: Computed tomography uses computed tomography dose index to estimate patient’s dose. However, it only accounts for scanner dose output using a reference phantom of unvarying size and content rather than patient`s morphology. The size specific dose estimate accounts for scanner dose output and patient size. There is no current documented diagnostic reference level established based...

Optically Stimulated Luminescence (OSL) of quartz is widely applied for equivalent dose (De) determination for sedimentary geochronology. Blue-light stimulated OSL (BOSL) is a widely accepted technique and dominated by the fast component, which is commonly attributed to electron release from a trap located approximately 2.8–2.9 eV below the conduction band. Although blue photons (~2.6 eV) are...

Radon is an odourless, colourless and tasteless noble gas which is highly radioactive in nature. It is of great concern because it poses a huge risk to man when inhaled and ingested. This study aims to quantify the concentration of Rn-222 in groundwater samples obtained from sources around artisanal gold and gemstone mining communities located in Southwest Nigeria and assess the lifetime...

Aquaculture environments can serve as pathways for naturally occurring radionuclides to enter the human food chain through fish consumption and water use. This study quantified the activity concentrations of polonium-210 (Po-210) in catfish tissues and radon-222 (Rn-222) in pond water from selected aquaculture habitats in Ekiti State, Nigeria. A longitudinal sampling design was adopted, with...

Dosimeters are typically calibrated in well-defined reference radiation fields; however, real-world radiation environments often deviate significantly from these conditions in terms of spectral composition, particle type, and angular distribution. Such deviations may lead to substantial underestimation or overestimation of the dose. To ensure reliable dose assessment, it is therefore essential...

Radon research in the Malá Stanišovská Cave (Low Tatras Mts., Slovakia) started in December 2024 and is planned for two years. Five monitoring stations were established along the tourist route, radon monitoring is performed using CR-39 track detectors, changed in one month and three-months intervals. The results obtained during the year 2025 showed the lowest radon levels at the cave entrance,...

ABSTRACT
Go to contribution page
As part of Phase V of the decommissioning of the A1 NPP in Jaslovské Bohunice, remedial actions are planned in response to radioactive contamination of the Manivier discharge canal banks, if it will be shown as necessary. The Manivier open channel was used as a discharge pathway for authorized and emergency liquid discharges from the A1 and V1 NPPs.
Nowadays, the riverbanks are... -

The fertilizer industry employs raw materials that naturally contain radionuclides. The processing of these materials during fertilizers production leads to the generation of by-products in which the initial radionuclide content is enhanced. One of the management practices implemented over the years has been the storage of this phosphate waste in open-air piles and ponds. Among the...

Radiation protection in underground workplaces, such as minning tunnels, requires systematic monitoring of occupational exposure. Workers are exposed not only to external gamma radiation originating from surrounding rock, but also to radon and its short-lived progeny present in the air. At established workplaces, monitoring strategies typically combine personal dosimetry with ambient...

The methodology of radiation surveillance has been transitioning from a manual, high-risk endeavor to a sophisticated, data-driven discipline. The current trend is to move beyond static, ground-based measurements, carried out by human personnel, toward a dynamic, autonomous Internet of Things (IoT) framework. This shift represents a fundamental evolution of the Unmanned Aerial Vehicles (UAV)...
