Cell phone radiation protection, some measures doesn't work

National scholars study found that cell phone radiation on the human central nervous system, reproductive system, etc. are all bad, expert tips, you can use your mobile phone by changing the way, the total amount of mobile phone electromagnetic exposure control, to reduce these negative effects.

However, many mobile phone radiation protection measures in some way have no scientific basis, is invalid. So let us look at what is invalid, which also is effective.

Invalid measures —

First, to the mobile phone on steering.

Because cell phone radiation is the antenna, while steering stick has been posted on the listening device, what effect?

Second, the choice of plastic shell of the phone.

Plastics and metal shell of cell phone radiation is the same, even the plastic shell of the phone, also be a layer of metal, used to keep the quarantine with the outside world.

III. purchase antenna external handset.

Whether internal or external antenna, radiation is the same. This is because the cell phone antenna materials and dimensions unchanged, even if mobile phone miniaturization or antenna built-in or external antenna radiation than strong.

4. the purchase of imported mobile phone.

All mobile phone production must conform to the European FTA certification standards, the standards prescribed by the radiation on all mobile phones are alike, so no import phones and mobile phone radiation than domestic.

Effective measures —

First, through instant cell phone away from the head.

Mobile phone signal just is switched on, the signal transmission system is not stable, at maximum power, radiation is strongest. Subsequently, cell phone radiation can rapidly reduce and keep in a stable state, so the phone is switched on, the moment was right away from the head.

Second, a long story short.

As a result of radiation thermal energy is generated by a build process, so you should minimize the per-use cell phone, and use the phone number of every day. Daily accumulated calls using your mobile phone should not exceed 1 ~ 2 hours.

Minimum of three, making a call.

According to the survey, using a mobile phone making a call and access telephone, radiation levels are different, making a call by the radiation intensity greatly exceeded into phone radiation intensity.

Fourth, alternating left and right ears.

5. a weak signal area less the call.

In the mobile phone display signal weaker when Description cell phone base station farther distance, cell phone radiation intensity will be larger.

6. as far as possible with headphones.

Mobile phone to the head of the radiation mainly near-field radiation, when the cell phone away from the head 30cm above, will significantly reduce the head of the radiation.

7. try not to pick up the phone when the battery is low.

8. try not to charge the phone.

9. sleep do not put the phone on a pillow.

Switch off the phone to stop the operation, the mobile phone itself or will release the amount of radiation, so sleeping or just let the phone away from your own comparison.
