Update from QVHD: A quick update regarding radon test kits. QVHD has exhausted our limited supply of free radon test kits. If there is any additional interest in kits, radon test kits can be purchased from the American Lung Association (1-800-LUNG-USA or www.lung.org), home improvement stores/local hardware stores, or can be done by a qualified tester. Visit CT DPH Radon Program website for a list of qualified radon measurement professionals (www.ct.gov/dph/radon).
