When cooled below the freezing point, radon exhibits a brilliant phosphorescence which becomes yellow as the temperature is lowered and orange-red at the temperature of liquid air. The main hazard is from inhalation of the element and its decay products which are collected on dust in the air. Recently, radon buildup in homes from the surrounding soil and rocks has become a safety issue and some areas around the world test homes for radon gas. It is the heaviest known gas. Radon is present in some spring waters. Table: basic information about and classifications of radon.

UNDERSTANDING RADON by G. Thomas Martin We realize most people find it difficult to understand radon; a colorless, odorless, inert radioactive gas. You cannot see it, smell it, or feel it; yet we cannot completely avoid breathing radon. There is about 0.35 pCi/L of radon in the outside air we breathe. Understanding the risks associated with radiation exposure is even more perplexing. I hope reading this article, will enable you to make an informed decision about the radon levels measured in your house. TABLE OF CONTENTS Section 1...Where Does Radon Come From? 2...How Does Radon Get Into The House? 3...What About Radon in Well Water? 4...What About Radon in City Water? ... 15...How Can I Learn More About Radon? 1. WHERE DOES RADON COME FROM? Radon comes from the natural radioactive decay of radium and uranium found in the soil beneath the house. The amount of radon in the soil depends on complex soil chemistry, that varies from one house to the next. Radon levels in the soil range from a few hundred to several thousands of pCi/L. The amount of radon that escapes from the soil to enter the house depends on the weather, soil porosity, soil moisture, and the suction within the house. 2. HOW DOES RADON GET INTO THE HOUSE?

See all General Household Safety Tips articles How to Test for Radon If you live in certain parts of the United States, you might be aware of the threat that radon gas poses. Radon gas is radioactive, and in tightly insulated houses it can accumulate to concentrations that pose a health threat. If you inhale the gas into your lungs, its decay can increase your chance of getting lung cancer. A study reported in 1990 by the National Safety Council estimated that about 14,000 deaths a year could be attributed to radon, and that the number could range from 7,000 to 30,000. In this edition of How Stuff Works , we'll talk about what radon is, how you can find it in your home and what the health risks are for it.

20. Radon Guide: Introduction To Radon Comprehensive guide to radon in the home provided by a firm of consultants in Northern Ireland. http://www.radonguide.com

RadonGuide.com HOME Contact About ... Radon Testing Methods Introduction to Radon Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil, rock, and water. Radon cannot be detected by sight, smell, or taste and is estimated to cause 60 deaths per year in Northern Ireland. It can become a health risk when trapped indoors where it can build to high levels. Radon can enter a home or building from the soil through cracks in the floor and walls; and openings around floor drains and pipes. Radon protection methods were first introduced into Part C of the Building Regulations (Northern Ireland) in June 1994. Although deemed-to-satisfy provisions are provided, no guidance on construction methods are incorporated within the appropriate Technical Booklet ("Technical Booklet C, Site preparation and resistance to moisture", June 1994). The Department of the Environment in conjunction with the British Research Establishment in March 1997 produced a draft Technical Booklet to cover these regulations. This draft is currently out for consultation and is due to become part of the Building Regulations (England and Wales) at the beginning of 1998. During the interim period, between June 1994 and March 1997, a number of Building Control (NI) advice notes and seminars were provided to fulfil the void left by the then new regulations. The draft Technical Booklet and the Building Control advice notes are based on the radon protection construction work undertaken in the South of England, where the highest indoor radon levels have been recorded within the United Kingdom.
