Radon - No this is not chemistry lesson.. its about our life

Get to know about Radon

Trust me... This is not a chemistry lesson. This is something which we all need to know. Have you ever heard of Radon? Radon is a colorless, odorless radioactive gas that seeps up from the earth. When inhaled, it gives off radioactive particles that can cause lung cancer. In fact, over 21,000 lung cancer deaths in the US each year are from radon, making it the second leading cause of cancer in the world.
While radon is present everywhere, in outdoors, radon quickly dilutes to very low concentrations and is generally not a problem. Your greatest exposure is where it can concentrate-indoors and where you spend most time-at home. Your home can have radon whether it be old or new, well-sealed or drafty, and with or without a basement.

You can’t see or smell radon. Testing is the only way to know your level of exposure. Radon can have a big impact on indoor air quality.

Radon comes from the natural (radioactive) breakdown of uranium in soil, rock and water and gets into the air you breathe. Radon can be found all over the U.S. It can get into any type of building—homes, offices, and schools—and result in a high indoor radon level. But you and your family are most likely to get your greatest exposure at home, where you spend most of your time.

Radons may be found in drinking water too. Radon gas can also dissolve and accumulate in water from underground sources (called ground water), such as wells. When water that contains radon is used in the home for showering, washing dishes, and cooking, radon gas escapes from the water and goes into the air. Some radon also stays in the water. Based on a National Academy of Science report, EPA estimates that radon in drinking water causes about 168 cancer deaths per year.Radon is not a concern in water that comes from lakes, rivers, and reservoirs (called surface water), because the radon is released into the air before it ever arrives at your tap.

This is what you need to know. If you’ve tested your private well and have a radon in water problem, it can be fixed. Your home’s water supply can be treated in two ways. Point-of-entry treatment can effectively remove radon from the water before it enters your home.Point-of-use treatment devices remove radon from your water at the tap, but only treat a small portion of the water you use and are not effective in reducing the risk from breathing radon released into the air from all water used in the home.

Here is what you need to do.
The easiest way to reduce radon is to keep all the windows of the home open, especially all of the basement windows. Keeping basement windows open helps to minimize the negative pressure within the lower part of the home and helps to dilute the radon. For this to work though, the windows need to be kept open all the time. If not, radon returns to full strength in as little as 6 hours.

Since radon is drawn into the house from the soil, sealing openings in the basement floors or walls with caulk can help to reduce the amount of radon entering the home. If you have a sump pump, seal the lid airtight. Cracks in the basement floors, walls and other openings can allow radon to come in easier so caulking work can make a big difference.

If you are building a new home, be sure to ask your builder to have a "passive" radon system installed during construction. The most effective way to get rid of radon is to install a removal system that draws the radon out of the soil before it even has an opportunity to enter the house. These systems are called "Sub Slab Depressurization Systems" or "Active Soil Depressurization Systems". These systems operate by using a piping and fan system that depressurizes the soil that surrounds the home.

I would like to thank my friend who brought this to my notice and helped me to share about such a serious issue with you all.
