What are alpha track detectors?
Each RSSI Alpha-track radon detector contains a detector element, called a foil. When radon atoms decay inside the detector, they release alpha particles. If the alpha particles strike the foil, they make microscopic tracks in the surface of the foil.
What is the alpha on the radon test?
We understand radon tests primary work when they are interacting with radon gas as it goes through one of its stages of decay. During this decay process, radon fires off alpha particles. These particles are traveling so rapidly that when the particles collide with a material, they can leave a ‘track’.
How do radon detectors work?
An active radon detector, on the other hand, isn’t a single-use device that takes months to work. It uses a sensor that detects radon by looking for alpha particles in the air — radon emits alpha particles; the more alpha particles in the air, the higher the concentration of radon in your home.
What is radon gases?
Radon is a radioactive noble gas that comes from the decay of radium in the soil. Radium is also a daughter or progeny nuclide of Uranium (Uranium decay). Radon is a colorless, odorless, invisible gas that can only be detected through the use of proper equipment and protocols.
How do you read a radon test kit?
Learn what the number of pico-Curies per liter means as it relates to the risk of damage and disease in your home or business.
- Greater than or Equal to 4.0 pCi/L. Above 4.0 pCi/L, you are putting yourself at unusually high risk for lung damage and cancer.
- Between 2.7 and 4.0 pCi/L.
- Less than 2.7 pCi/L.
How accurate are home radon detectors?
The National Radon Safety Board evaluates radon measurement devices in cooperation with the US Environmental Protection Agency. It requires that the individual relative error of each device be less than or equal to 20.0% and that the precision error of all devices be less than or equal to 20.0%.
How accurate are radon detectors?
The monitors had a range of uncertainty from 2%–15% with a range of precision from 1%–24%. The monitors performed better at higher radon levels than at levels near the Canadian guideline level of 200 Bq m−3, and slightly better during ‘summer’ conditions than during ‘indoor winter’ conditions.
How does a continuous radon monitor work?
Active radon detectors such as continuous radon monitors and continuous working level monitors require operation by trained, state-certified testers. They work by continuously measuring and recording the amount of radon or its decay products in the air of the home.
How accurate are home Depot radon tests?
Findings show radon tests of less than 90 days are imprecise up to 99 percent of the time.
Which radon test is the most accurate?
The Radon Eye RD200 tops our list for its fast, accurate readings. After setting up this radon detector, you’ll get your initial reading within the first 10 minutes with a more accurate reading appearing within the next 60.
Are electronic radon detectors accurate?
Are continuous radon detectors accurate?
Long-term and continuous testing provide a much longer period of time for collecting readings, which allows you to better determine the average radon level in your home. These test devices cost more and take longer, but they are the most accurate radon test kits available.
