Green technology: From steel mills to wind farms?

A Spanish wind turbine maker puts down roots in Pittsburgh. Yes, Pittsburgh.

PITTSBURGH — Steelworkers tending blast furnaces and rolling mills in Pittsburgh 30 years ago could not have imagined that their jobs would turn so green, or that they would be working for foreign companies that needed their skills.

Reality beckons for geothermal energy dream

EVERY time Resources Minister Martin Ferguson makes an announcement regarding geothermal energy he likes to quote the statistic that just 1 per cent of Australia’s geothermal resources could power Australia for 26,000 years.

But does he really believe it can even power Australia one time over? The pace and quantum of the government funding for geothermal suggests he is not entirely convinced.

He wouldn’t be the only one.

How can I tell if I have too much of radon in my home?

How can I tell if I have too much radon in my home?
Illustration of a Radon testing kitRadon is tricky. You can’t see it, and you can’t smell it. So, the only way to know how much radon you have in your home is to get a test kit and do a test.
You can buy test kits at a lot of different stores — hardware, lawn and garden, outdoor supply, and department stores. They cost about $25 and take just a few days to do. Then you send your test kit in to a laboratory, and they tell you how much radon you have in your home.

How does radon get into my house?

How does radon get into my home?
Detailed image of how radon seeps into a homeBecause radon is a gas, it can sneak into your home through the tiniest little cracks, cracks too small for you to see. Since radon comes from the soil and rocks in the ground, it usually gets into our homes through the basement or foundation — the part of your house that sits underground.
Any little cracks in the foundation or basement floor and walls will let radon in, and so will leaks in seals around basement windows or sump holes, used to help get rid of water, in the basement floor.

Why is radon bad for us?

Radon is a radioactive gas. Radioactive means this gas gives off bursts of energy which we can’t feel, but when they hit our bodies, they are harmful. When our bodies are hit by too much radioactive energy, we can develop serious diseases. One of these diseases is cancer.
Because radon is part of the air we breathe, it is taken into our lungs. Radon is the second-leading cause of lung cancer in the United States, with only smoking cigarettes being worse. Learn more about lung cancer from the American Lung Association.

Where does radon come from?

Radon comes from the rocks and soil that make up the ground on which we live. When the uranium in the rocks and soil breaks apart, which happens naturally, one of the things created is radon gas. This gas then becomes part of the air we breathe.     Image of a house and the ground below. Beneath the surface is the word radon.

Does indoor quality air affects our health?

Indoor air quality can also affect your health.
There are many sources of indoor air pollution in any home. These include combustion sources such as oil, gas, kerosene, coal, wood and tobacco products; building materials and furnishings; products for household cleaning and maintenance, personal care or hobbies; central heating and cooling systems and humidification devices; and outdoor sources such as radon and pesticides.

For example, you can’t see, smell or taste radon, but it is a gas that is harmful to your health. Radon can be found in buildings, such as homes, offices and schools. One way radon can get into buildings is by cracks in the basement, and if the ventilation is not good enough, radon levels can be harmful.
