Radiation from hand held electronic devices

I've been using those devices since they've been available and my hands are like vice grips with lizard-like healing abilities.so maybe the effects of radiation are positive?

At least you are aware that the Radiation is said devices is harmful.

The best policy is to stop using them and for sure stop running Wifi if you are doing so. There are oufits that make protective devices. One is called Bio Geometry, and there are others if you go looking. Look at all published work by Barrie Trower, Microwave Weapons expert. This is just getting started. Was it necessary to implement these devices in this frequency and wavelength range? No it absolutely was not. Will they have to be re-engineered long term. Yes for sure they will.

If you look at the real science, not the fradulent pseudoscience the results will be shocking. Same thing goes for switched mode power supplies that throw what is know as " Dirty Power." All of this Tech is harmful to Biological life.

the harmful effect of EMF radiated from hand held devices such as Mobile phone, PC mouse?

What makes you think that this is true?

Define Harmful?

As these pieces of equipment have to meet certain standards, in order for them to be harmful they would need to exceed the safe levels by a very significant amount.

There are not too many wireless devices operating at the Kilowatt range of RF output.

Most WiFi/Bluetooth 3/4/5G devices operate at the micro/milliwatt range of RF output, basically in the noise floor of the spectrum's they occupy.

Walking outside in the chill of the night would subject you to a higher level of EMF.
