Abstract
Inhalation of radon and its progeny are the most important component of public exposure to natural radiations. Many epidemiological studies have established the fact that radon and radon progeny are associated with increased incidence of lung cancer. Beside health concerns, radon is an important consideration in other fields, e.g. hydrological research, detection of geological fault lines, prediction of earthquake, uranium deposits and oil exploration. The importance of the subject compelled many scientists to develop methods for measurement and mitigation of radon. During last decade many studies for measurement of radon and thoron have been conducted in Azad Kashmir. In most studies, the techniques used involve the usage of solid state nuclear track detectors. Building materials, including granite, marbles, gravel aggregates, bricks, sand and soil have been characterized through radon exhalation rate studies. Several research articles have been published, reporting indoor radon measurements in dwellings and at workplaces. Though these studies have provided preliminary information about radon levels in the area, however, data obtained are still unable to convey clear information to readers. This review paper attempts to organize the radon data to provide a clearer understanding and roadmap for radon measurements in Azad Kashmir.
