Adoption of wireless charging has been fairly slow, but it could pick up if it worked over longer distances. Now, engineers at Aalto University have developed a new system that can allow more efficient wireless power transmission over longer distances.
And does it cause cancer? Does it wipe your credit cards?
Cancer, not at all. This is not capable of generating UV rays. Heck, not even visible light.
Right, I wasn’t under the impression that it did. But radiation does exist across the electromagnetic spectrum. Are they able to calculate the long-term exposure amounts and deem them safe?
Yes. Not all radiation has the capabilities of causing cancer.
Look up ionizing radiation. You need that to damage cells.
That begins at the middle of UV spectra. Less than that, it can’t (it’s related to the photoelectric effect and Compton effect)
You cannot make visible light to produce cancer. It’s not physically possible. And microwaves, wifi and cellular radiation has less energy than visible light.
@kier I am no expert, but there are I believe other mechanisms that could *maybe indirectly* cause cancer with certain kinds of radiation. I feel like cell damage from microwave- or infrared-induced heat could release free radicals or create some other carcinogenic chemicals.
But that’s not a direct result of the radiation. Direct DNA damage from radiation only occurs with ionizing radiation, as you mentioned.
And since we’re talking about visible light, I’m not aware of any way, indirect or otherwise, that visible light could cause cancer.
