Finding Ways To Keep Up With Tests

Understanding Radon Testing and Expert Recommendations

A test is necessary to know whether your need a radon mitigation system. Because radon can’t be seen or smelled, special equipment is necessary to detect its presence.

Depending on the devices used, radon tests come in two types – passing and active.

Passive Testing

There is no need for power to work with passive radon testing devices. Charcoal liquid scintillators, charcola canisters, electret ion chamber detectors and alpha-track detectors are examples of such devices. In general, passive radon devices – both long-term and short-term – are priced cheap.

Active Testing

As opposed to passive testing, devices used for active testing testing devices, which provide hourly as as well as full test readings, need power to run. These devices include continuous radon monitors and continuous working level monitors, both of which make active testing more expensive.

Understanding the Process of Radon Testing

To understand what makes radon devices different from one another, and to know which ones are most appropriate for your needs and foreseen testing conditions, you may want to consult a local or state official. Be sure to get a radon testing device from a qualified laboratory. Radon exposure can increase a person’s risk of getting lung cancer. Hence, a radon-certified contractor installing a radon mitigation system in your home can practically save your family’s life.

Radon amounts in the air are often measured in picocuries of radon per liter of air (pCi/L). Sometimes, test results can also be expressed in Working Levels (WL) instead of picocuries per liter for air. In a typical house, 0.016 WL is equal to around 4 pCi/L.

A radon abatement system should be in order at such a level. The U.S. Congress is aiming to keep indoor radon levels less than outdoor. Outdoor air usually has a radon level of pCi/L. If one long-term test of your home or the average of two short-term tests reveal radon levels at 4 pCi/L (0.016 WL) or higher, EPA recommends mitigating measures.

Present technology allows the reduction of most homes’ radon level to 2 pCi/L or even less. Radon mitigation can also be considered for a radon level reading of 2 pCi/L to 4 pCi/L. A long-term radon test stays in your house for over 90 days, while a short-term test will remain for 2 days to three months. Each radon test should be taken for at least 48 hours. Shorter-term tests yield quicker results, but longer-term ones give you a more accurate picture of the year-round average radon level of your home, as well as indicates if a radon mitigation system is needed.

Radon Testing Recommendations from EPA

Radon testing is recommended by the EPA in two categories. One is for homeowners whose house is not for sale, and the other is for radon testing and reduction in real estate deals. One is for radon testing and reduction in real estate deals, and the other is for homeowners with no intention to sell their houses.
