background: several epidemiological studies conducted on underground miner’s show that exposure to elevated levels of radioactive radon gas is expected to increase the risk of lung cancer. relative risk of lung cancer is almost linear with radon exposure. elevated concentrations of radon are not only reported within mines but also for closed indoor environment of general public houses. measurem...

Radon contributes with more than 50% to the dose equivalent to the public coming from natural sources, and is a major risk factor for lung cancer occurrence (10–14%, in Europe, p.a.) which should be investigated. Insufficient data on radon levels exist for Romania up to now and further extensive surveys are needed. The paper presents a series of in-situ indoor radon data in various locations in...

introduction cr-39 detectors are widely used for radon and progeny measurement in the air. in this paper, using the monte carlo simulation, the possibility of using the cr-39 for direct measurement of radon and progeny in water is investigated. materials and methods assuming the random position and angle of alpha particle emitted by radon and progeny, alpha energy and angular spectrum that arri...

Introduction: Radon is a colorless inert gas which decay products are the main component of natural radioactive elements that are naturally produced in under layers of earth crust by decay of radium and uranium. It enters through buildings via gaps and cracks. Radon gas decay products like alpha particle can increase the incidence of lung cancer in human. Since every person sp...

background: many public health agencies rank residential radon exposure as the second leading cause of lung cancer after cigarette smoking. it has been shown that the risk coefficient for lung cancer is higher for children than that for adults. therefore, indoor radon measurements were carried out in the elementary schools of tulkarem province, west bank, palestine. materials and methods: two h...
