Radon is a type of radioactive gas that is known for causing cancer, and although you cannot see, smell or taste radon, it can in your home. As soon as you begin breathing in air that has radon in it, you are at risk of developing cancer because of it, and so it is literally life threatening and you need to take the matter seriously into consideration.
There are things that you can do in order to ensure that you do not have a problem with radon in your home, and the best thing of all that you can do is use a radon kit. Radon kits are used to determine whether or not there are levels of radon in a home and if so how high these levels actually are. This allows you to be aware of the situation and whether or not you are going to have to take steps to take care of it.
There is no real way of determining when or why you should test for radon and purchasing radon kits and testing is the only real way that you are going to be able to determine what the levels are of radon in your home. It is definitely worth checking to make sure, and even if you find that there is no radon at all in your home, at least you know now and will not have to worry about it.
Once you have used the radon kits in your home, if you do find that there are high levels of the radon gas present, then there are things that you can do in order to reduce the concentrations. You can either attempt to tackle the problem yourself although you will most likely want to seek some sort of DIY radon mitigation help first, and then you also have the option of hiring a contractor to do the work for you, but you should realize first that this will most likely run you anywhere from $700-$2500.
You should also locate an NEHA-certified mitigation contractor either way so that you have a professional who will assess the situation and even if you did tackle the problem on your own, they will be able to double check for you and make sure that the problem has been taken care of.
You can also have a radon mitigation system installed directly in your home rather than using radon kits and the major advantage to this is that you will constantly have lower in-home radon levels, as long as the system is installed correctly and is operating properly.
