5G is a little higher at 3.4GHz to 3.6GHz, but that's tiny when you consider that microwaves go up to 300GHz. And visible light comes in at a range of around 430THz to 770THz. That's more than a thousand times higher than the maximum microwave – and 100,000 higher than 5G. Dangerous radiation, like UV rays, X-rays and gamma rays are also far higher up the spectrum still. Early theories suggested 5G could lead to cancer – and now crackpots have linked it to coronavirus too. But it's simply impossible for 5G to cause any of these problems. Radiation damages cells by breaking them apart, but 5G microwaves simply lack the power to do this. 5G is a low-frequency radiation, far below infrared and visible light.
In fact, it's essential that 5G is low-frequency, because higher frequencies are less useful at delivering mobile signals over large areas. We know that this level of radiation is safe, because otherwise the visible light from our televisions would have killed us a long time ago.
