There’s an entire industry in China around design and production of anti radiation mobile phone chips. These stick-ons cost very few but will sell for ten dollars or more. Do anti radiation mobile phone chips work? Or are they just a hoax?
A radiation chip is usually a small foil of gold or silver. It is a few microns in thickness and is laminated to provide sturdiness and stability. It is stuck to the mobile phone by a layer of adhesive material. There are other variations to this configuration. It is claimed that fixing this product to the back cover of the mobile phone effectively reduces cell phone radiation by 90-99%!
This is a product I do not endorse at all. I refute its claim as EMF radiation absorber. There is indeed no science, reason and logic to these products. Indeed, these products serve to severely aggravate the cell phone or device radiation profile and are prone to cause more damage than the device itself.
Do anti radiation mobile phone chips work? The answer is simply “NO”.
The antenna architecture of cell phones vary from maker to maker. A Samsung architecture may be completely different from Apple of Xiaomi. Even within the same maker, the architecture may differ model to model. Antenna and PCB architecture is a complex science. Generally these are protected by a large number of patents. Antenna architecture may vary due to technology, phone size, network status, phone battery life, circuit miniaturization or feature addition and many other factors.
Therefore, fixing a metal strip without any consideration to the geometry, PCB layout, Antenna patterns will never help eliminate cell phone radiation. Fixing such stickers and chips could rather obstruct signal reception causing the phone to radiate in higher amounts.
If you are concerned about your cell phone radiation effecting your health, DO NOT BUY these anti radiation mobile chips or stickers.
All you need to do is to increase the distance between your phone and yourself, or hold the phone at an arms length and talk through an earphone and use texting as against calling. Or use an earphone.
