Does cell phone need 'radiation shield'?

At present, almost everyone uses mobile phones. This creates an extremely potential market for "radiation shielding" products, which are advertised to block electromagnetic fields emitted by the device. The question is: "Radiation shield" for cell phones is really needed?

In recent years there has been growing concern about the risk of cancer of EMF from mobile phones. As a precaution, some people use the headset instead of holding the mobile phone close to the head when speaking. Others buy specialized products, called "EMF shields", for attachment to mobile phones to prevent harmful electromagnetic waves.

However, experts say, radiation shields for phones are not really needed.

This is because mobile phones are not dangerous. Experts cite many reasons for the view that harming EMF waves from mobile phones is unreasonable in science.

For example, magnetic field-induced fields are not strong enough to break down the molecular and chemical bonds in human cells. Thus, they can not destroy human cells like ionizing radiation. In addition, the electromagnetic fields generated by the cell phone inside the human body are much weaker than the electromagnetic fields that appear naturally in our body.

"There is no scientific basis to demonstrate the harmful effects of EMF on human health," said the latest published study.

In addition, most of the "radiation shields" available on the market are not adequately tested for their ability to limit or reduce the amount of EMF emitted by mobile phones.

Consumers may be spending money to buy really unnecessary and unnecessary equipment.
