Airtech Radon Testing and Laboratory ANALYSIS is a certified Radon facility that offers radon testing & analysis for charcoal canisters. Radon is the second leading cause of lung cancer only second to smoking.The way to determine if your house has a level above the EPA/DEP level of 4.0 pCi/L. is to perform a test. Just because your neighbor does have or doesn't have radon is NOT an indication of what the concentration would be in your home...all homes are different. That is why it is recommended to test each & every home!
