Lung cancer is the only known health effect linked to radon exposure at this time. The EPA estimates that betw of the , annual deaths from lung cancer may be attributable to radon exposure. In New Jersey, of the annual 4, lung cancer deaths, as many as may be associated with radon exposure.

Within the past few years several situations have been brought to light which indicate an increased radiation exposure of certain segments of the general population caused by human activities.   Biological response of exposure to radon progeny has long been investigated, but there are only few studies in which absorbed doses in lungs of laboratory animals were estimated. The present study is the first attempt to calculate the doses of inhaled radon progeny for mice. For reference, the doses for rats and humans were also computed with the corresponding models.

Author information: (1)Department of Atomic and Nuclear Physics, University of Bucharest, Magurele (Ilfov), Romania. [email protected] Cigarette smoking may change the morphological and physiological parameters of the by: In Comparative Dosimetry of Radon in Mines and Homes, an expert committee uses a new dosimetric model to extrapolate to the home environment the risk relationships found in the miner studies.

Important new scaling factors are developed for applying risk estimates based on miner data to men, women, and children in domestic environments.

INTRODUCTION. In the current lung dosimetry models for the inhalation of radon progeny, the calculation of dosimetric and microdosimetric quantities are commonly based on two main assumptions: (1) the tracheobronchial tree is represented by a sequence of bifurcating straight cylindrical airways (), and (2) radon progeny activities are uniformly distributed within the mucus-serous source Cited by: W.

The health effects of exposure to low and moderate levels of radiation are the appearance, at long times after exposure, of a small excess of cancers in any irradiated population and, one or more generations later, of a small excess of genetic disorders.

The more important for setting radiation protection standards is the risk of radiation induced cancer.

Evidence in humans on the interaction between cigarette-smoking and exposure to radon. Radon - the killer in tobacco. Out of the nearly 4, chemicals found in tobacco smoke, only two definite chemical carcinogens have been found - benzopyrine and nitrosamine.

However, the most potent carcinogen in tobacco is radiation from the radioactive products of radon. Polonium is the only component of cigarette smoke that has produced.

Witherspoon ABSTRACT Within the past few years several situations have been brought to light which indicate an increased radiation exposure of certain segments.

Radioactivity in Cigarette Smoke Winters-TH, Franza-JR New England Journal of Medicine, ; (6): To the Editor: During the 17 years since the Surgeon General's first report on smoking, intense research activity has been focused on the carcinogenic potential of the tar component of cigarette smoke.

When radon in air decays, it forms a number of short-lived radioactive decay products, known as radon progeny, which include polonium, lead, bismuth and polonium The inhaled short-lived radon progeny are particles that can deposit within the respiratory tract.1.

Introduction. Tracheobronchial deposition of radon progeny ( Po, Pb, Bi and Po) in the human body is believed to lead to lung cancers, and the bronchial region was shown to be the most radiosensitive region in the respiratory tract (ICRP, ; Nuclear Energy Agency, ; James, ).In this connection, immense effort has been devoted to assess the bronchial dose from radon.These units are now frequently replaced by SI-units.

In SI-units, the conce 9 tration of radon in air is expressed as Becquerels per cubic meter (Bq/m); at radioactive equil brim between radon and its progeny, one WL corresponds to x 10 3 Bq/m 3. Cumulative ex osure in SI-units is.
