Short-term radon inhalation induces significant survival adaptive response in Balb/c mice
According to the World Health Organization (WHO), the main health hazard from high radon exposure is an increased risk of lung cancer. In this study, 60 male Balb/c mice (20-30 g) were randomly divided into four groups of 15 animals. The animals in the 1st group were kept for 72 hours in an ordinary cage while the 2nd, 3rd, 4th groups were kept in cages with artificially elevated levels of ...

Effects of chronic radon-related external and internal irradiation: assessment of the dose effect curve below 200 mGy
The long-term effects of professional exposure to radon are well-known. They result from the combined action on the lung epithelia of α-radiation due to radon inhalation and deposition in the lung of its decay products and external γ-radiation from uranium, thorium and their progeny. According to the guidelines applied by the USEPA and recommended by the ICRP, the maximal exposure in ...

Exposure to radon in tourist caves in Cuba
With the objective of estimating the dose due to radon-222 received by tour guides and other people who work inside some of the most important tourist caves in the Republic of Cuba, measurements of radon concentrations were carried out in four of these caves. All the studied caves are located in Vinales Valley (Pinar del Rio City), a very important tourist area in the country. The relationship ...

One century of radon therapy
Supplementing a recent review, "Health effects of high radon environments in Central Europe: another test for the HLNT hypothesis", this review of medical radon applications (in particular for the treatment of painful degenerative joint and spine diseases) covers mainly the first century of large-scale use and scientific studies on this subject since the discovery of radon. Most of the studies ...

Radon Air Stripping of Well Water
Radon is Frequently Found in Ground Water Radon, symbol Rn, atomic number 86, is a colorless, odorless gas at ambient conditions. It is the heaviest element of the Noble Gas family. As such it is extremely stable and unreactive chemically. But it also is highly radioactive. Its half-life is only 3.8 days. Both Thorium, symbol Th, atomic number 90 and Uranium, symbol U, atomic number 92, have no ...

Water Contaminants and Their Treatment
Because many water contaminants are invisible and odorless, samples should be tested to determine a treatment plan. Many steps may be necessary to make water potable Many traditional sources of fresh water, both surface water and groundwater, may carry visible and invisible contaminants that make it unsuitable for consumption. The World Health Organization (WHO) has established Guidelines for ...

Prevention measures against radiation exposure to radon in well waters: analysis of the present situation in Finland
Naturally occurring radioactive elements are found in all groundwaters, especially in bedrock waters. Exposure to these radioactive elements increases the risk of cancer. The most significant of these elements is radon which, as a gas, is mobile and dissolves in groundwater. In Finland, water supply plants are obliged to carry out statutory monitoring of the water quality, including radon. ...

Ionising Radiation
Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...

Measurements of 226Ra, 232Th and 40K using gamma spectrometry to assess a first-order exposure risk for residents of Western Haryana, India
The measurements of 226Ra, 232Th and 40K using gamma spectrometry and measurements of radon concentration and exhalation rates using solid-state nuclear track (LR-115, Type-II plastic) detectors were used to assess a first-order exposure risk for people residing in the Fatehbad and Hissar districts in Western Haryana, India. The concentrations of radium, thorium and potassium in the soil samples ...

Monitoring radon and its progeny in the environment of the vertical 15 UD Pelletron accelerator facility
Environmental radioactivity due to radon and its progenies in the ambient air at the vertical 15 UD Pelletron accelerator facility of the Inter University Accelerator Centre, New Delhi, India was evaluated to calculate the annual effective dose to the workers and users. The radon activity was measured with an active monitor. The activity concentrations of the radon progenies were measured ...

Application of Monte Carlo Analysis for Assessing Radiation Doses and Risks to Humans
ABSTRACTThis BIOMASS Theme 2 report has been produced by the Remediation Working Group, which is concerned with the evaluation of the reliability of dose and risk assessment methodologies applied in support of decisions related to the cost-effectiveness of risk reduction measures within an environmental remediation programme. Scenarios have been developed concerning the site contaminated by an ...

The radiological impact of the presence of radon, thoron and their progeny in the environment of a liquid petroleum gas bottling plant
The seasonal variation of the activity of radon, thoron and their progeny has been measured, and the annual exposure, lifetime fatality risk and annual effective dose to the workers in a Liquid Petroleum Gas (LPG) bottling plant due to exposure from a mixed field of radon and thoron have been calculated over the four seasons of the year. The measurements were carried out using a passive ...
