Radon in New Minnesota Homes

Starting in 2009, the Minnesota State Building Code adopted Appendix F of the International Residential Code. Since then, all new homes built to the standards of the Minnesota State Building Code have been built with at least a passive radon mitigation system, or in some cases, an active system. This was done to help deal with high levels of radon in Minnesota; approximately 40% of homes in Minnesota have elevated levels of radon gas.

Steele County Deals With Radon Problem

A dangerous gas is seeping into homes throughout Steele County — a gas that carries adverse health effects — and the homeowners may not be aware of it.

According to data from the Minnesota Department of Health, high levels of radon — an odorless, tasteless and invisible gas that has been known to cause lung cancer — are present in 67 percent of the homes in Steele County.

Two-thirds of the homes in Steele County have levels of at least 4 picocuries per liter. A picocurie is one-trillionth of a curie, an international unit of measurement for radioactivity. Dan Tranter, supervisor of the Indoor Air Unit at the state’s health department, said radon poses a risk to those living in high concentrations.

Mitigation Reduces Radon Gas in Dodge County Courthouse

Several months ago, Dodge County staff members discovered that some rooms in the old courthouse basement tested positive for radon gas.

There are no standards for the allowable amount of the toxic gas for non-residential buildings in Minnesota, but county commissioners decided to proceed using the strict limits required for residences. The Environmental Protection Agency recommends mitigation if more than 4 picocuries are recorded during radon testing in homes.

(A picocurie is a unit for measuring radioactivity equal to one trillionth of a curie. The curie is based on the observed decay rate of about one gram of radium.)

Radon gas is the second-leading cause of lung cancer in the United States.

New Minnesota Health Department Codes Insufficient

According to the preliminary results of a study launched last fall by the Minnesota Health Department, 20 percent of new homes being built have radon levels above 4.0 picocuries per liter. This is well above the point that the U.S. Environmental Protection Agency regards as safe. Before a new state building code went into effect in 2009, approximately 40 percent of homes tested come back at unsafe levels. The 2009 code change was supposed to reduce the risk of radon exposure in Minnesota.

Health officials are still concerned that the code leaves some homeowners exposed to deadly levels of the cancer-causing gas. The passive radon mitigation systems installed under the code do not do the job sufficiently. “That is still a quarter of our population being highly exposed to something that gives lung cancer,’’ says manager of the Minnesota Health Department’s radon program, Joshua Miller. They are not always effective at reducing radon levels below the federal health safety standard.

KARE 11 Investigation: Radon Test Results Above EPA Standards

Committee OKs Radon Work

Radon in the Knox County Courthouse has been a plague on county employees and officials for a decade or more. But county officials are hopeful that radon will be a thing of the past, as the county Building Committee on Tuesday approved a radon remediation plan and provided funding for a new heating and cooling system that will increase the building’s air pressure and keep radon levels at bay.

Sheriff David Clague informed the Building Committee in June that parts of the courthouse housing employees, jurors and records tested over the acceptable levels of radon, an odorless, tasteless gas that is the second leading cause of lung cancer. Clague, as well as county employees, railed against the Building Committee and the County Board for their inaction on the radon levels, saying tests dating back to 2002 showed dangerous levels of the gas.

Knox County Looks for Solution to Radon Problem

News and Weather For The Quad Cities -

The Knox County Board met Wednesday evening to talk about the high radon levels at the county courthouse.

According to the EPA, any radon level of 4 pCi/L or greater is dangerous. So when employees at the Knox County Courthouse got a report stating some radon levels in the building were greater than 60, they were concerned.

The Knox County Board addressed those concerns at Wednesday's meeting and the board members said they're trying to come up with a plan to solve the problem.

Advanced Radon Mitigation Urges New Hampshire Residents to Test for Radon

Advanced Radon Mitigation Urges New Hampshire Residents to Test for Radon

Radon is odorless, tasteless, and a public health menace, according to a representative of Advanced Radon Mitigation, which has been helping New Hampshire residents test for and mitigate radon since 1997.

“According to the EPA, radon is the second leading cause of lung cancer, only exceeded by cigarette smoking. For non-smokers, radon is actually the leading cause of lung cancer. If you are anywhere in New Hampshire, you should have a radon test conducted in your home. It could save your family’s life.

The EPA – or Environmental Protection Agency – has been vigilant in reminding Americans of the dangers posed by radon ever since the Indoor Radon Abatement Act was passed in 1988, a measure which required the EPA to list and identify areas in the United States with the potential for elevated radon levels. By the EPA’s categorization, there are three radon zones in the country – with zones 1 and 2 presenting the highest and “moderate” risk for radon contamination.

Radon Threat Grabs Attention of Lawmakers

Make Radon Testing Part of Real Estate Transactions

An estimated one in three Minnesota homes harbors high levels of radon. However, testing for the radioactive gas before buying or selling a home can lead to reduced health risks, according to the Minnesota Department of Health (MDH).

Radon is the second leading cause of lung cancer in the United States, with more than 21,000 deaths attributable to radon each year. It is the greatest environmental cancer risk and the leading cause of lung cancer among non-smokers. Yet radon exposure is largely preventable.

MDH estimates that one in three Minnesota homes have radon levels that pose a considerable health risk of lung cancer over many years of exposure. Homes with high radon levels are fixable, but first they must be tested. MDH is highlighting radon testing during National Public Health Week, April 1 through 7.

Testing for radon during the sale of a home is an opportune time:
