Joel Gray is a certified Instrumentation and Radio Technician with a degree in Electronic Telecommunications; and earned his Bachelor of Science degree in Electrical Engineering with Honors at the University of Texas at Dallas with a Minor in Nanotechnology. Completed coursework has included intensive classes in Electromagnetics, RF Design, Communication Systems and Signals & Systems and he has had extensive experience in troubleshooting a broad variety of technical problems, particularly EMI / RF interference issues with industrial and biomedical equipment.

He is also an official member of the Texas Society of Professional Engineers and has nearly completed a second engineering degree (Bioengineering & Biomedical Engineering) along with pursuing his Professional Engineering license.

Formerly Accredited and licensed as a Mold Assessment Consultant with the State of Texas.
He has also attended an official course for Radiation Safety Officers offered by the TCEQ (Texas Commission on Environmental Quality), and recently completed advanced courses in Biology, Organic Chemistry, Engineering Physiology of the Human Body, Microbiology, Biomaterials and Medical Devices so as to better understand the effects of pathogens, toxins, biochemical reactions, radiation and other environmental factors at the physiological, cellular and bio-molecular levels. In addition, he has a background in commercial construction which is often useful for understanding building science issues.

He has been testing radon gas and radiation for over 16 years and blogs regularly on the subject and dangers of radon (and other indoor air quality pollutants) at:
