I haven't watched the video, but I assume it is based on her 2010 book

Paul Brodeur is the New Yorker science reporter who first brought to public attention the problems of asbestos and ozone depletion, which he considered his two big accomplishments (this is from my vague memory of reading his biography, "Secrets: A Writer in the Cold War" (1987).
At the time he wrote Secrets, he said that he had no strong epidemiological proof that radiation of high-tension power lines was dangerous, but the pattern of obfuscation and industry response was identical to what he had seen for tobacco, asbestos and similar stories he covered. That, of course, is from the 1980s. But that stuck in my mind as we became a wireless society.
Tim Ferriss claimed that he had very poor sperm count (or some measure of sperm health) and as an experiment, he put his cell phone in his backpack and kept it in airplane mode 80% of the time. After something like 3 months, his counts had improved dramatically, though he also says he made some dietary changes.
And finally, the strength of a radio signal decreases as a square of distance.
This is super important with respect to something like a cell phone that is transmitting (or pinging towers to see if it has any signal or messages). If you have it in your front pocket, 1cm from your testicles and move it to a backpack 32cm away, it is 0.1% as strong. If you have it on your ear and then move it to the passenger seat in the car, that's also perhaps 0.1% or less of the exposure to your brain.
Also, cell phones increase their power in areas like mine with worse signals. So if you're in a rural area with a cell phone in your pocket vs an urban area with a cell phone in the passenger seat, you are getting literally 10,000 times the exposure.
Similar math applies to your wireless router. Don't put it on the shelf right next to your desk.
