Metodo di acquisto del vestito premaman-Protezione dalle radiazioni

Many pregnant mothers do not pay attention to the role of Maternity Dress during pregnancy, thinking that as long as you buy more loose clothes than usual, it is not the case.

Maternity Dress is very necessary for pregnant mothers during pregnancy, and pregnant working mothers must first see whether they are radiation-proof when choosing Maternity Dress. When verifying whether Maternity Dress has a radiation-proof effect, you can start from the following four aspects.

(A) stainless steel metal fiber radiation protection clothes how to identify good or bad.

Can you shield electromagnetic waves, many people use radiation detection pens, but there is no how to do. Very direct method, pick up the landline phone, dial the cell phone next to the phone. When the mobile phone is dialed out, it will interfere with the microphone, and the radiation protection clothing is separated between the mobile phone and the fixed phone, and the interference disappears, which proves that your clothes have the effect of shielding electromagnetic radiation. Measured by the above method, both pieces of clothing have a role, then how to distinguish between the two pieces of clothing which shield effect is good? Each piece of clothing has a sample cloth, after the sample cloth is burned, look at the burned metal fiber network, which network is dense, and the metal fibers are arranged neatly, indicating which effect is good, the metal mesh is arranged in disorder, and the effect is not arranged neatly.

(2) How to compare the effect of metal fiber and silver fiber, which is better?

Test with a multimeter, the smaller the resistance, the better the shielding function. The same distance test results, metal fiber type resistance is significantly greater than silver fiber type, silver fiber shielding range is wide. If the signal is relatively strong in the place of silver fiber can wrap the mobile phone can not get through, stainless steel metal fiber slightly almost.

(3) Silver fiber radiation test method

The silver fiber is a nylon filament silvered, so it cannot be tested by burning sample cloth method. Silver fiber radiation protective clothing can generally shield mobile phone signals with clothes to wrap the mobile phone, half a minute signal basic attenuation is zero.

(4) Cover the errors of mobile phone signal testing, in different locations and in different directions. What's more, the results of measurement are not the same at the same time, don't blindly believe in the bag mobile phone.

In addition to mobile phones, there are many household appliances and office appliances will produce harmful radiation sources, close distance radiation is harmful to the body, and far field signals can not cause harm to the human body.

Can that bag of phones prove to be effective? The bag mobile phone is just an intuitive proof that the clothes you buy have a shielding effect, that is, as long as you pack for a while, as long as there is a weakening of the signal, it is proved that there is a shielding for use, but it is not necessary that the phone has no signal. That is to say, in different locations whether the package of the mobile phone effect is not the same.

The correct way to test with a cell phone is to dial the cell phone from a landline. Pick up the receiver next to the phone line and hear the electromagnetic interference on the phone. Put your clothes between your cell phone and the phone line, and the electromagnetic interference disappears.
