The present study involves the measurement of radionuclide contents and radon/thoron exhalation rate in soil samples collected from 30 villages Jammu district, J & K, India. Thallium-doped sodium iodide detector advanced Smart Rn Duo monitor were used for rates. radon flux was also measured by using a surface chamber technique. mass has been found to vary 15 ± 0.4 38 0.8 mBq kg?1 h?1, while tho...

Risk perceptions are the basis for radon risk decisions by both scientists and the general public. Since radon cannot be detected by any of our five senses, which most people rely upon to warn them of danger, much of the general public does not perceive radon as a significant risk. Likewise, many health physicists, with many years of training and experience in dealing with significant radiation...

This article uses grounded theory methods to research the history of a therapeutic community and highlights the possibilities of ‘being able to learn’ as an aim for history of medicine research. For this case study, processes of research and learning allow consideration of the ‘dilemma of paternalism’ and the interaction between history, policy and practice. How can students enter into discours...

Magnetic and radon anomalous fields are essential geophysical entities of environment which determine to a considerable degree its ecological state. Revelation magnetic zones is an urgent task for the studies geo-environmental state territory appraisal safety. The greatest danger produced by areas where faults localized with anomalies related in upper part Earth crust. For Kyiv geological chara...

Radon concentration was measured in ground floor of two buildings with moisture controlled sub slab construction and slab on the ground. Results show that radon concentration in ground floor of the building with moisture controlled sub construction is more than 11 times smaller than that of the building with slab on the ground. Also indoor radon concentration in this building is about %41 highe...

Background: In this study are submitted the radon concentration measurement results of four underground mines: Stanterg, Artana, Hajvali and Badovc, which are owned by Trepça Enterprise, Kosovo. The mines have the same geological formation and from these mines are extracted ores rich with lead, zinc, silver, and gold. The radiation exposures caused by radon and radon daughters was determ...

  Based on the last presented reports of UNSCEAR, inhalation of radon gas and its short-lived decay products is a major contributor to the human exposure from natural radioactivity. Lung cancer is the known effect on human health from exposure to radon in air. Radon is found in outdoor air of buildings of all kinds. The main important isotope of radon is 222Rn. Radon (222Rn) is a noble gas...

A primary challenge from the relativist to the contextualist about epistemic modals is to explain eavesdropping data—i.e., why the eavesdropper is inclined to judge the speaker as having uttered an epistemic modal falsehood (when she is so inclined), even though the speaker’s utterance is true according to reasonable contextualist truth conditions. The issue turns in large part on the strength ...
