    About radon General information about radon. Radon is an invisible, odourless and tasteless radioactive gas. It exists naturally in most rocks and soils from where it can migrate up, through the ground, through foundations, into buildings. Radon is also emitted from certain building materials fabricated from rock having naturally high uranium. Currently there are o radon test results in the database. The DOH goal is to provide analysis of this data and policy recommendations, at the county level, to the local health districts. Previous limitations of the available data precluded a comprehensive county-by-county analysis of radon File Size: KB.

The more radon you are exposed to, and the longer the exposure, the greater the risk of eventually developing lung cancer. Radon is the second leading cause of lung cancer in the United States, resulting in 15, to 22, deaths per Size: KB.

      According to the report of World Health Organization, the risk of lung cancer observed in underground miners due to exposure on radon, was the main reason to investigate similar risk for the general population, due to radon exposure in houses, working places, and buildings. However, there are significantly different conditions in mines and Cited by: The generalised Radon transform is a well-known tool for detecting parameterised shapes in an image. Applying the Radon transform to an image results in a parameter response function (PRF). Curves in the image become peaks in the by: 4.

Revised risk assessment by EPA’s Office of Radiation and Indoor Air (ORIA) for exposure to radon in homes. In response to a request by ORIA, the Radiation Advisory Committee (RAC) of the Science Advisory Board (SAB) has reviewed the methodology used in this report for estimating cancer risks from radon.

An initial advisory, finalized inFile Size: KB. A computer code dedicated to indoor radon risk mapping is presented, based on geology and on indoor radon measurements. Assuming a lognormal distribution of the data at the local scale, it. A smoker who is also exposed to radon has a much higher risk of lung cancer.

Overall, radon is the second leading cause of lung cancer. Radon is responsible for ab lung cancer deaths every year. An overview of the Health Effects of Radon.

Radon Exposure Risks The primary health risk from radon is lung cancer from inhalation of the radon and its decay products. Radon in water is a risk primarily when released to the air and subsequently inhaled (It is estimated that the risk of stomach cancer from the ingestion of water containing radon is only about one-tenth as great as the risk of lung cancer).

CARBDOSE. The CARBDOSE program was rewritten in to use the same NAS–NRC radon health risks as UR3M. This update of risk factors is particularly significant for the ingestion risk for radon in water, which is 4 times less than thought in CARBDOSE reports risks via inhalation and ingestion separately as risks of cancer per 10 : S.

Health risks of radon stem from its breakdown into “radon daughters,” which emit high-energy alpha particles. These progeny enter the lungs, attach themselves, and may eventually lead to lung.

Radon as a health risk in civil engineering Contact with radon is in most cases not harmful to human health and life. There are situations, however, in which engineers should be aware of such risks.

It is assumed that the concentration of radon in the air is 10 Bq/m3, which is about half the dose of radiation which people are exposed to from Cited by: 2. radon, you will receive a lab analysis report that will highlight a number that is either above or below the Health Canada action level of Bq/m 3.

Health Canada recommends taking remedial action at an indoor radon level of Scientists agree that radon causes lung cancer in humans. Recent research has focused on specifying the effect of residential radon on lung cancer risk. In these studies, scientists measure radon levels in the homes of people who have lung cancer and compare them to the levels of radon in the homes of people who have not developed lung cancer.

Passive radon detectors are small and discreet when in use, and the whole process including laboratory analysis is inexpensive. As radon levels fluctuate according to seasonal and occupational variances (e.g. amount of ventilation through opening windows), a three month period is normally recommended to take such inconsistencies into account.

But that message skips over many complexities surrounding the risks from radon. Radon is a heavy, radioactive gas that can seep out of the soil into basements and other parts of a house.Home Buyer’s and Seller’s Guide to Radon U.S.
