“Finally, I want to say thank you again for taking the time to provide ‘expert’ EMF services to the ExxonMobil Baytown Medicine and Occupational Health (MOH) group. We truly appreciate your timeliness, professionalism, and your willingness to continue follow-up communications with Nevro related to the testing parameters of this specific implant device, even after your field time here at our facility was completed.”

Review on YELP! from a medical doctor that paid for a phone consultation:


“We consulted with Joel at ScanTech because the house we are constructing happens to be in close proximity to a major power transmission line. Being a physician and concerned mother of two young kids, I became concerned about the so called association between EMF and health issues. On line research and even reviewing medical research articles did not put my worry to rest but a conversation with Joel really addressed all my concerns and finally put my mind at ease. As an electrical engineer specializing in nanotechnology, Joel is extremely professional and is a thorough expert in his field. He has a vast fund of knowledge and experience in his field. He not only answered all my questions but also put things in the right perspective. I am truly grateful that we consulted with him and would strongly recommend him to anyone looking for answers or solutions in this field.”

From Zillow.Com on the subject of Should I Buy I House Near Power Lines:


From Trulia on How Close or What is the Distance from Power Lines Is Safe:

“Any advice you might receive on this forum will be completely inadequate to provide you with the data or guidance you need to make an informed decision regarding your concern. As part of your research efforts to find an answer to this question, consider hiring a qualified professional who is trained to analyze, test, and respond on the subject.

In the DFW Metroplex, we can recommend Joel-Anthony Gray with ScanTech for his inspection and consultation services, and have had multiple families hire him to help determine the possible risks associated with buying a particular home — or within a particular proximity — to high tension power lines and to gauge possible EMF exposure.

One surprising nugget I can share with you is that EMF and radiation can come from other sources WITHIN homes as well. While your focus might be on power lines for the immediate time frame, what you might learn about equally or higher potential sources of exposure coming from flat screen TVs, computer monitors, water heaters, appliances, etc… may be a big eye opener for you.

Good afternoon, Joel!
Thank you very much for the report and specially for investigating about the exposure for the kitties!
It was really nice meeting you too, chatting and clearing all my doubts and concerns. I think for the first time I am really enjoying being in the house, instead of always worrying in the background of my mind about a possible excessive exposure…
I guess that’s why people keep you for 4 hours, to let out all their worries and concerns and move on, living happily ever after. 🙂
Thank you again and have a great weekend!

“I used ScanTech, owned by our own neighborhood resident and frequent-Nextdoor-poster JAG Man, to check the air quality in our home. I was very pleased with his responsiveness, thoroughness, and analysis.
He gave me the complete picture of the situation and explained things in a way that made it easy to understand and absorb. I would not hesitate to use him again and highly recommend him for investigation and consulting.”
