New York State sent a notification to each Home Inspector stating that Home Inspectors need to receive certification from NYS, Dept. of Health in order to legally test for radon. I called to confirm this, and have a letter from New York State which states it is a crime to test for radon without specific New York State authorization.
If anyone wants a copy of the original letter, e-mail me, call me or snail mail me and I will send you the letter which requires anyone without NY State approval to cease and desist any activities involving radon testing.
I was surprised, and am glad they sent me the letter to show fellow NACHI members in New York State this. I have sent a copy to all of our chapter members.
Much luck and success, fellow NACHI Members.
