Radon gas emissions
Without the proper equipment or technical knowledge, you could actually increase your radon level or create other potential hazards and additional costs. The combined effects of cigarette smoking and radon exposure raise the risk of lung cancer much more than either exposure alone.
Owens and Ernest Rutherford, at McGill University in Montrealnoticed variations when trying to measure radiation from thorium oxide. Follow the instructions for leaving the kit in your house for the required number of days.

If you have a private well, you can have it tested for radon. Although high concentrations of radon in groundwater may contribute to radon exposure through ingestion, the inhalation of radon released from water is usually more important. In addition, studies in Europe, North America and China have confirmed that even low concentrations of radon — such as those found in homes — also confer health risks and contribute significantly to the occurrence of lung cancers worldwide. High death rates from lung problems among miners in some parts of the world were first noted hundreds of years ago, long before people knew what radon was. This may damage the cells in the lining of the lungs and increase a person's risk of lung cancer. In lab studies using human cells, radon and its progeny have also been shown to cause damage to chromosomes packets of DNA and other types of cellular damage. Radon levels are usually higher in basements, cellars or living spaces in contact with soil. Should you test for radon? What expert agencies say Several national and international agencies study different substances in the environment to determine if they can cause cancer.
Be aware of possible symptoms of lung cancer, such as shortness of breath, a new or worsening cough, pain or tightness in the chest, hoarseness, or trouble swallowing, and tell your doctor if you start to have any of these symptoms.
Radon gas in the air breaks down into tiny radioactive elements radon progeny that can lodge in the lining of the lungs, where they can give off radiation. Straightforward and effective techniques exist to reduce the concentration of radon in drinking-water supplies by aeration or using granular activated carbon filters.
What is radon used for
Radon is present outdoors and indoors. Be aware of possible symptoms of lung cancer, such as shortness of breath, a new or worsening cough, pain or tightness in the chest, hoarseness, or trouble swallowing, and tell your doctor if you start to have any of these symptoms. In fact, smokers are estimated to be 25 times more at risk from radon than non-smokers. Radon has no stable isotopes. It is normally found at very low levels in outdoor air and in drinking water from rivers and lakes. EPA lifetime safety standards for carcinogens are established based on a 1 in , risk of death. These sources of water normally have higher concentrations of radon than surface water from reservoirs, rivers or lakes. Department of Housing and Urban Development pdf icon[1 MB]external icon recommends additional actions you can take to reduce high radon levels in your home and protect yourself from an increased risk of lung cancer. This value refers to the annual average. Therefore, the uranium-bearing source in the west Basin and Range Province and higher permeability in the east basin area could be contributing factors for the spatial characteristics of radon concentration and fluxes observed in the Capital of China. Information about the program is available at www. The equilibrium factor found in epidemiological studies is 0. Radon decays in a sequence of radionuclides called radon decay products, radon daughters, or radon progeny.
Because of these fluctuations, it is preferable to estimate the annual mean concentration of radon in indoor air by measurements for at least 3 months. Qualified contractors can be located through state radon offices, which are listed on the EPA website at www.
The equilibrium factor is also lowered by air circulation or air filtration devices, and is increased by airborne dust particles, including cigarette smoke.
Cigarette smoking is by far the most common cause of lung cancer in the United States, but radon is the second leading cause. Studies done in the lab Studies in lab animals have also shown an increased risk of lung cancer with exposure to radon.
