How can I choose the best radon gas detector?
Radon gas is odorless, tasty and colorless radioactive gas, which naturally occurs with the disintegration of radium. Radium is a naturally occurring chemical in most soil and rocks. Usually, radon gas is released into the atmosphere, there is such a small amount that it is not considered harmful. Recent studies suggest that radon gas can accumulate in limited areas and can cause potential health risks, including lung cancer. In recent years, several types of radon detectors have been available for homeowners and builders. They include passive, short -term detectors and active long -term detectors. Reflections on the right choice include whether the electricity source is available, whether the detector is on site or constantly use and what size it is necessary to check.
Passive, short -term radon gas detector does not require electricity. Usually it contains a coal container that is exposed to air in the home for a short time. Test period for passive detectors withThey differ according to the manufacturer. Some radon gas detector sets require three to seven-day trial periods, while others are designed to test 90 days or one year. At the end of the test period, the canister is supplied to a company that can safely test the sample on the level of dangerous radon gas. These companies usually send a letter to the house owner with test results.
The active radon gas detector is powered by electricity and can monitor radon gas levels for twenty -four hours a day. Most models have digital reading and the alarm sounds when the radon gas level becomes dangerous. Radon is measured in units called Picocury, which measures the speed of radioactive decay - 1 Picocuria equals the decay of two radioactive atoms per minute and is usually measured in picocuria per liter (PCI/L). According to the Life Mode Agency for the protection of L (EPA) in associated withDads, long -term exposure to radon gas levels above 4 PCI/L, is considered a potential health risk.
Carefully monitor the instructions when using a passive or active radon gas detector. The key to the successful radon gas test is the correct location of the detectors. Radon gas is a heavy gas that tends to accumulate in low -lying areas, such as basements, cellars and the first floors that come into direct contact with the soil. The radon test set should be located at the lowest level of a possible house and high humidity or dives can disrupt the exact reading of the radon gas.
Extensive test kits with multiple radon reading are available to suppliers and builders of new construction. These tests can also detect radon levels in large existing buildings. The soil can also be tested for radon gas emissions before the start of new construction. These tests are usually called Open Land test sets and generally work in a tstejný manner as inWinging detectors.
