background: nowadays, extensive technological advancements have made it possible to use nanopaints which show exciting properties. in ir iran excessive radon levels (up to 3700 bq m–3) have been reported in homes located in radon prone areas. over the past decades, concerns have been raised about the risk posed by resi- dential radon exposure. objective: this study aims at investigating the eff...

background: radon, thoron and their progenies are the most important contributions to human exposure from natural sources. radon exists in soil gas, building materials, indoor atmosphere etc. among all the natural sources of radiation dose to human beings, inhalation of radon contributes a lot. the work presented here emphasizes the long term measurements of radon, thoron and their progeny conc...

Background: It is considered that if radon gas is inhaled and ingested, it is the primary health risks for lung and stomach cancers. This paper presents the measurement results of radon activity concentrations both residential tap water and dam water for Kastamonu city Centre-Turkey. Materials and Methods: The radon activity concentrations of water samples collected from 60 tap waters at four l...

BACKGROUND Studies of underground miners exposed to radioactive radon and its decay products have found that exposure increases risk of lung cancer. Consequently, when radon was found to accumulate in houses, there was concern about the public health impact from exposure to a known carcinogen. Estimates on the basis of studies of underground miners suggest that indoor radon may account for 6000...

BACKGROUND Burning incense generates large amounts of air pollutants, many of which are confirmed or suspected human lung carcinogens. OBJECTIVES We conducted a population-based case-referent study to examine the effect of incense smoke exposure on lung cancer risk among Chinese males and explored the joint effect of cigarette smoking and exposure to residential radon. METHODS We recruited ...

Radon exposure to the public contributes more than half of all the radiation doses caused by natural radiation; accurate measurement of radon progeny is quite essential for the dose evaluation of radon exposure in environment. For the purpose of establishing a radon progeny standard and controlling measurement quality of commercial devices, it is quite important to analyze the efficiency of dif...

ABSTRACT Background: and soils with which it comes in contact. There is dual exposure from radon in water i.e. due toinhalation of the radon released from the water into the ambient air and through ingestion whenwater is used for drinking. As radon contaminated water adversely affects the health, it istherefore fundamental from health and hygiene point of view to measure radium concentrationand...

The International Agency for Research on Cancer (IARC) in 2012 upgraded its hazard characterization of diesel engine exhaust (DEE) to "carcinogenic to humans." The Diesel Exhaust in Miners Study (DEMS) cohort and nested case-control studies of lung cancer mortality in eight U.S. nonmetal mines were influential in IARC's determination. We conducted a reanalysis of the DEMS case-control data to e...

Environmental risk factors for Multiple Sclerosis (MS) are not clearly understood, although vitamin D and sunlight exposure are thought to be protective. MS prevalence increases with increasing latitude, in a pattern similar to that of residential radon exposure, particularly in the U.S. To further study this relationship, a pilot study was conducted of ninety-seven MS patients and 51 non-MS pa...

This article proposes a review of past and current ICRP publications dealing with the management of radon exposures. Its main objective is to identify and discuss the driving factors that have been used by the Commission during the last 50 years so as to better appreciate current issues regarding radon exposure management. The analysis shows that major evolutions took place in very recent years...
