Office of Disease Prevention and Health Promotion: Test Your Home for Radon: Quick tips

Test your home with a short-term test. Test your home again if the radon level is 4 or higher.
If your home has a radon level of 4 or higher, fix your home.
Be sure to hire a contractor who is qualified to fix radon. It’s a good idea to get at least 2 price estimates. Find a radon professional to fix your home.

The District of Columbia Department of Environment & Energy: Radon

Testing your home for radon is as simple as opening a package, placing a radon detector in a designated area, and after the prescribed number of days, sealing the detector back in the package. Fixing a radon problem is usually just a matter of caulking cracks along basement foundations, sealing leaks around pipes, and taking other steps to prevent radon from entering the house through places where it is in contact with the ground.

The District of Columbia Department of Environment & Energy (D.O.E.E.) provides district residents with a free radon test kit by calling the radon hotline at (202) 535-2302 or by submitting request a free radon test kit.

An overview of instrumentantion for measuring radon in soil gas and groundwaters

Instruments for the measurements of radon and its decay products in earthquake research are based mostly on the detection of alpha particles. The devices and methods used, depend on whether the techniques measure radon or radon decay products, and the duration of the measurements, of which there are three types: (i) grab or instantaneous; (ii) integrating; and (iii) continuous. Other criteria used in the design of these instruments are field measurements applicability, portability, convenience and reliability. With the recent increased demand for radon and radon decay products measurements, instruments development has focused on the design of appropriate devices for short-term measurements, as well as on more complex and sophisticated instruments for long-term measurements used in radon research for geophysical, geochemical and hydrological studies.


The role of the implementation of policies for the prevention of exposure to Radon in Brazil—a strategy for controlling the risk of developing lung cancer

Lung cancer is the leading cause of cancer death in the United States and other industrialised countries. The most important risk factor is active smoking. However, given the increased incidence of lung cancer in non-smokers, it is necessary to improve knowledge regarding other risk factors. Radon (Rn) is a noble gas and is the most important natural source of human exposure to ionizing radiation. Exposure to high levels of this radioactive gas is related to an increased risk of developing lung cancer. The objective of this work is to highlight the importance of measuring indoor concentration of this gas and identify which steps should be taken for achieving radiological protection.

Radon Potential, Geologic Formations, and Lung Cancer Risk

Exposure to radon is associated with approximately 10% of U.S. lung cancer cases. Geologic rock units have varying concentrations of uranium, producing fluctuating amounts of radon. This exploratory study examined the spatial and statistical associations between radon values and geological formations to illustrate potential population-level lung cancer risk from radon exposure.

•We examine spatial and statistical associations between radon and rock formations.
•Observed radon levels vary significantly by geologic formation category.
•Four rock types are associated with high radon levels.
•Mapping both rock formations and radon values may be better than radon alone.

Radon Testing: Community Engagement By a Rural Family Medicine Office

Objective: Iowa has the highest average radon concentrations in the nation, with an estimated 400 radon-induced lung cancer deaths each year. Radon is the second leading cause of lung cancer death overall. The objectives of this study were (1) to educate the population attending a family medicine office about the dangers of radon, (2) to encourage homeowners to test for radon, (3) to work with the community to identify resources for mitigation, and (4) to assess the utility of working with a local family medicine office as a model that could be adopted for other communities with high home radon concentrations.

Methods: Participants obtained a US Environmental Protection Agency– certified activated charcoal
short-term radon kit through their primary care office or by attending a seminar held by their medical
office. Participants completed a short investigator-developed questionnaire about their home, heating, and demographics.


Reducing Home Exposure to Radon and Secondhand Smoke

Lung cancer is preventable through eliminating tobacco smoke and radon exposure. We examined the association between demographic factors and home testing at baseline of a larger RCT to test the effects of a tailored environmental feedback intervention to reduce home exposure to radon and secondhand smoke (SHS) with homeowners and renters.

A purposive sample of homeowners (n=340) and renters (n=47) were recruited at an outpatient medical facility using stratified sampling to ensure equal proportion of those exposed to SHS in the home. Homeowners were randomly assigned to treatment or control groups. Demographics, perceived risk of lung cancer, smoking status, past 7-day SHS exposure in the home, and lung cancer worry were assessed at baseline. Free test kits for radon and SHS were provided to treatment group participants and renters at enrollment; they received $20 to test their homes. Controls could call to request free test kits.


Calculation of lifetime lung cancer risks associated with radon exposure, based on various models and exposure scenarios.

The risk of lung cancer mortality up to 75 years of age due to radon exposure has been estimated for both male and female continuing, ex- and never-smokers, based on various radon risk models and exposure scenarios. We used risk models derived from (i) the BEIR VI analysis of cohorts of radon-exposed miners, (ii) cohort and nested case-control analyses of a European cohort of uranium miners and (iii) the joint analysis of European residential radon case-control studies. Estimates of the lifetime lung cancer risk due to radon varied between these models by just over a factor of 2 and risk estimates based on models from analyses of European uranium miners exposed at comparatively low rates and of people exposed to radon in homes were broadly compatible. For a given smoking category, there was not much difference in lifetime lung cancer risk between males and females.


Predictive analysis and mapping of indoor radon concentrations in a complex environment using kernel estimation: An application to Switzerland

The aim of this study was to develop models based on kernel regression and probability estimation in order to predict and map IRC in Switzerland by taking into account all of the following: architectural factors, spatial relationships between the measurements, as well as geological information.

•Kernel regression was used to map indoor radon concentration in Switzerland.
•Our model explains 28% of the variations of radon concentration data.
•Maps were generated considering different architectural elements and geology.
•Maps showing the local probability to exceed 300 Bq/m3 were proposed.
•We developed a confidence index to assess the reliability of the probability map.
