The paper presents results of radon (Rn) and thoron (Rn) levels in different parts of some selected plants used in Moroccan cooking and traditional medicine. Plant uptake of radionuclide is one of many vectors for introduction of contaminants into the human food chain. Thus, it is critical to understand the soil–plant relationships that control nuclide bioavailability. The radon and thoron conc...

background: inhalation of radon and its short-lived decay products is one of the ‎most significant sources of exposure to natural radiation. radon is the second cause ‎of lung cancer in the populations. the present study was carried out under the projects of ‎national radon, with the aim of determining the concentration of indoor in the city of qom ‎located in the central semi-arid region of ir...

The study concerns the analysis of 220Rn (thoron) recorded in surface soil two sites Campi Flegrei caldera (Naples, Southern Italy) characterized by phases volcanic unrest seven-year period 1 July 2011–31 December 2017. Thoron comes only from most layer, so characteristics its time series are strictly connected to shallow phenomena, which can also act at a distance measuring point these particu...

Introduction: Exposure to indoor radon increases the risk of lung cancer. This study examined the level of indoor radon in dwellings of Khorramabad city, by using passive alpha-track detector (CR-39) during winter of 2016. Materials and Methods: In the present study, we detected the concentration of indoor radon in 56 dwellings. A passive sampling instrument (alpha-track detector with CR-39 pol...

In the editorial published in the journal of Radiation Protection Dosimetry, Tommasino, Falk and Fujimoto (2003:104, 99-100) proved that Pinocchio, Tengu and Trolls, thanks to their long noses, are very able to protect themselves from thoron exposure. The present paper is aimed at a more ambitious goal, which is to prove that Pinocchio, Tengu and Trolls are also very able to measure thoron (plu...

Background: Radon concentration was measured in the soil and indoor of Amman and Al- Rusaifa cities in Jordan during summer season. Materials and Methods: The measurement was performed using time-integrated passive radon dosimeters, containing a solid state nuclear track plastic detector, commercially known as CR-39. Results: Radon concentration levels in the soil ranged from 2.8 ± 1...

This study aimed to investigate the differences in relationship between radon and its progeny concentrations particulate matter under varying pollution weather conditions. Outdoor were measured by a radon/thoron- radon/thoron monitor (ERS-RDM-2S) during haze dust storm Beijing. Particulate meteorological data simultaneously recorded. Results showed that exhibited diurnal variation pattern, with...
