It takes about 48 hours usually, and the house has to be sealed during the entire test. Windows must remain closed, although you can go in and out the front door normally.
Most of the time it is included in your home inspection. There is no way to test a house before you buy it or rent it, unless the seller agrees to a pre-offer test, which is not likely.
There are no agencies that test for Radon, it is something you are responsible for. Keep in mind that it is nothing to worry about. If you buy a house and the readings are too high, you can just have the seller install a radon remediation system, which amounts to a foundation ventilation system.
Easy fix, relatively cheap, and radon levels are reduced to background levels.
Radon can vary from one house to the next, so every house must be individually tested. Radon readings also change over time. Just because your house passes once does not mean it will always pass.
