Frequently Asked Questions

• What is radradon and why is it dangerous?

  Radon is a colourless, odourless radioactive gas. It’s formed by the radioactive decay of small amounts of uranium that occur naturally in all rocks and soils.

• What is radon and its decay products?

  The short lived decay products of radon are responsible for most of the hazard by inhalation. Radon and its decay products called radon daughters or radon progeny emit highly ionizing alpha-radiation. Decay products are suspended in the air which we breathe.

• Where can I find information about radon in the UK?

  Public Health England (PHE) is the UK’s primary expert on radon and radiation protection. PHE provides resources and advice about radon for the public, including individual householders, industry, education and research. The UKradon website has more information about radon, including: health risks.

• What do we know about radon and radiation protection?

  For most people, radon is the single largest source of radiation exposure whether they are at home or at work. Public Health England ( PHE) is the UK’s primary expert on radon and radiation protection. PHE provides resources and advice about radon for the public, including individual householders, industry, education and research.

• What is radon and how does it affect your health?

  There’s always some radon in the air around us. The problem is when radon gas from underneath a home leaks in through cracks or gaps. Too much of it can build up inside. When you breathe in radon gas, the radioactive particles can get trapped in your lungs. Over time, they can cause lung cancer. The risks from radon depend on two things:

• Where can I get radon data?

  To request other radon data sets for research purposes, please contact Angela Leek, Bureau Chief for the Bureau of Radiological Health at (515) 371-2255. EPA - Radon In Schools Website: www.epa.gov/radon/radon-schools

• What is radon gas?

  Radon is a gas that you cannot smell, taste or see. Radon forms naturally when uranium, radium and thorium break down in rocks, soil and groundwater. People can be exposed to radon primarily from breathing radon in air that comes through cracks and gaps in buildings and homes.

• How common are high radon levels in Wisconsin?

  About 1 out of 10 homes in Wisconsin has high radon levels. Radon is a naturally occurring gas that is radioactive and can cause lung cancer.
