Technology risk without safeguards

Thu Nov 5 05:56:38 UTC 2020

Hi Suresh, 

I'm not disputing anything you or Tom wrote. The current scientific consensus is that most RF exposures are sage. We agree on that. 

My point is simply that, as Tom wrote in his citation, the biological effects of RF are still an area of research. 

And for that reason, it's unfair to dismiss a physician's suggestion to look into a case as an "internet conspiracy". That's all. 

Thanks, 

Sabri
