Background: Everyone is exposed to radon because it is present everywhere with varying concentrations. Radon and its progeny are well established as lung carcinogenic. Materials and Methods: Track etch technique using LR-115 plastic track detectors has been used to measure the effective radium content and radon exhalation rates in soil samples collected from urban area of Etah district...

background: radon is an odourless, colourless and tasteless gas and it is the first cause of lung cancer among non- smokers. the assessment of the level of radium in building materials helps in understanding the radiological implications. it has been observed that everyone has some levels of exposure to them. therefore measurement of radium and radon in the soil samples are important from publi...

The mainly sources for indoor radon concentrations in all types of houses are the soil radon flux under the building (about 80%) and the radon exhalation from building materials (about20%). Our paper presents two methods for simultaneous measurement of this exhalation from soil and building materials: (1) -charcoal adsorption, respectively (2)-Lucas cell method. The both methods are applicable ...

One of the aims of the First Intercomparison on Natural Radioactivity Under Field Conditions was to test different instruments and detectors for the measurement of radon gas and external gamma radiation (dose rate) in filed conditions, where the levels of natural radiation are quite high. The event was organized by the Radon group of University of Cantabria, (Spain) LaRUC, and was held in the e...

abstract  background: the essential constituents of cements like lime, silica and alumina are derived from earth’s crust in which radioactive elements like uranium, thorium etc are also present in varying amounts almost everywhere. these two elements are considered as the parent elements of uranium and thorium radioactive decay series in which radon and thoron are produced respectively as decay...

BACKGROUND People are exposed to ionizing radin from the radionuclides that are present in different types of natural sources, of which phosphate fertilizer is one of the most important sources. Fertilizers are commonly used in agricultural field worldwide to enhance the crop yield. MATERIALS AND METHODS In the present investigation, a control study was carried out on the lady's finger plants...

In the present investigation, soil samples were collected from 10 villages belonging to Pathankot district, Punjab, India and assessed for radium content using LR-115 plastic detector. The ‘track etch’ technique has been employed for measuring the radium content. From the radium content, radon exhalation rates and mass exhalation rates were calculated for these samples. The mass exhalation rate...

High radon concentrations indoors usually depend on the possibilities of radon penetration from the surrounding soil into the buildings. Radon concentrations in dwellings up to 100 kBq/m3 were found in some special regions (i.e. Schneeberg/Saxony, Umhausen/Tyrol), where the soil shows a high uranium content and additionally, a fast radon transport in the soil is possible. To reduce the radon ex...
