Buyer’s Guide – What To Consider While Buying A Radon Detector?
As you can see, there are so many different radon test kits at present, and it often confuses the buyer. Before we discuss the factors that are necessary to understand while buying the best radon detector, you have to understand what Radon is?
What is Radon?
Radon is a noble gas, which means it is nonreactive, colorless, and odorless. However, it is in gaseous form and has a half-life of 3.8 days. Though it is nonreactive, it is radioactive. If inhaled, it could pose some serious health issues.
Radon is generated by the decay of highly radioactive elements such as uranium and thorium. These elements have a half-life of several billions of years. Even though the Radon’s half-life is short, the elements that produce it have billions of years of half-life. Hence, it is generated continuously.
As for the nature of radon gas, it is one of the densest gases on the earth. As a result, it stays near the ground. Or in the case of homes, it is mostly found in the basement or ground floor.
Fortunately, it depends on the geology and chemistry of the terrain you reside in. But it is the trace amount of uranium and thorium that makes continuous radon. So over the period, it could get accumulated in the surroundings. That is why it is necessary to keep the radon gas test kit in-house. It may not pose an immediate danger, but keeping an eye on the radon level will help you stay prepared when the gas hits the danger mark.
Type of Detectors
Most people do not have a good understanding of the radon test kit. So, buying the best radon detectors for home without any confusion, require a clear picture of it. The first thing to understand is how many types of radon detectors are there. Generally, there three types of radon test kits:
Factors To Look For In A Radon Gas Detector
There are several factors that you need to understand to make an informed decision on your purchase.
Accuracy is one of the most important factors to consider while buying a radon gas test kit. Because it is all about knowing the level of Radon in your home. Radon as gas is odorless and colorless. Hence, there is no other way to see the change in the gas level. If the detector doesn’t provide you accurate results, you are inviting a major health issue. Yes, of course, the radon detectors can be off by a few percent, but make sure the detector you buy allows the error of only up to 10 percent. Radon Eye RD200 Smart Radon Monitor Detector is one of the most accurate radon test kits. Accuracy is the key when you are professional like home inspector.
Generally, we associate connectivity with home security systems, but as the technology has progressed, the home radon test kits have evolved. The radon detectors have become smarter. They can now connect to your phone or any other device that supports WiFi or Bluetooth. If you want to keep an eye on the radon level daily and don’t want to bend your back, trying to read the numbers on the detector monitor, smart detectors are perfect. The smart detectors will send you the results right to your phone. So wherever you may be, you can see the current radon level on your phone. If you want to buy a WiFi radon test kits, go for Radon Eye RD200 Smart Radon Monitor Detector Plus.
One limitation every radon gas detector has that it can measure the radon gas only in a single room. To measure the gas in other places, you need to move the detector. All the devices can be fixed on the wall or to a ceiling. But have the easy option of moving like Airthings Wave Smart Radon Detector, which uses only one screw to fix on to a wall. Hence, it can be easily removed.
4. Ease of Use
For any device, it is the most crucial factor. If you don’t know how to operate or do not understand the numbers it shows, there is no use of buying such a device. A radon gas detector’s job is to show the radon gas level and alert if it crosses the critical limit. Even if you don’t know what the numbers mean, but if it shows some kind of visual representation of the data like Airthings Wave Radon Detector does, makes it much easier to understand for an average user. The Airthings smart detector shows the color code to show you the current level of gas. Most of the smart devices show data on the phone and sends a notification if the gas level goes beyond the danger.
All the reputed manufacturers of the best radon detectors offer a warranty. It may be one year or two years. Always check with the seller or manufacturer. Warranty is important because you want a detector working at its optimum level. If something goes wrong, you should be able to fix it quickly and efficiently. But the best way to fix it is through the manufacturer. Some are known to replace the malfunctioning device if the device is still in warranty.
Some detectors use AA or AAA batteries as a power source. The good thing about batteries as a power source is it allows the mobility of the detector. Most of the battery-operated radon detectors last up to 1 to 2 years. After that, a fresh set of batteries is required. Make sure when you are buying, see how long the batteries last for the device. The main reason being you will have to change them before they die down. Also, even with low power, the device may seem operational, but it may not show accurate results. Detectors work better only with full power.
Why Should You Check Radon Levels In Your Home?
Radon is a radioactive gas that is formed by the decay of radioactive elements in the soil. The gas is generally released in the air from the cracks under a building or the bodies of underground water or surface water. The radon levels vary from one area to another. In general, Radon is typically present in the lower ground radon levels or neighborhoods like the basement, crawl space, sump pumps, rivers, lakes, and construction joints. In such areas, the ventilation is deficient, and the gas can reach higher radon levels much easier.
The National Institue of cancer says radon gas is the leading cause of lung cancer, and second is cigarette smoking. Anyone who smokes regularly or in and around a high levels of Radon is at a higher risk of lung cancer. So, to stay away from such a deadly disease, it is always advisable to check the radon levels in your home and keep them too minimum or zero levels if required.
Despite being invisible, odorless, and tasteless, Radon is hazardous to health. As per the US EPA data, radon exposure is the most significant cause of lung cancer. People die more due to radon exposure than due to carbon monoxide poisoning, house fire, another disease, and drowning.
The Radon affects your health as the radioactive particles from the gas directly go into the lungs and release lot energy and thereby damaging the lung tissue and ultimately causing lung cancer. Nevertheless, you won’t get lung cancer if you are exposed to Radon for one day, or everybody who is exposed to radon levels will get lung cancer. As per the data, 4% of non-smokers ger lung cancer due to radon exposure. So, for a better healthy life, it is advisable to check the radon levels in your home.
