Can Radiation Protection Clothing Really Protect Against Radiation?

In July 19th, the China Consumers' Association announced the results of a comparative test of 21 radiation protection garments.

The results show that expensive silver fiber materials

And ordinary metal materials.

There is no obvious difference in performance, and clothing style has greater influence on shielding effectiveness.

On the whole, the smaller the opening and the longer the length of the garment, the better the shielding effectiveness.

The staff of the China Association for Consumers Association bought 21 samples at the physical stores and online stores on the basis of ordinary consumers. It mainly involves two main types of materials in the market, namely, silver fiber radiation protection clothing and metal fiber radiation protection clothing.

The sample involves 11 brands, covering the main brands in the market.

The price of the sample involves 3 intervals: 10 yuan for 400 yuan / piece, 400 to 1000 yuan / 8, 1000 to 1500 yuan / 3.

Styles include vest skirt (sleeveless, shoulder, back cover), harness (sleeveless, back cover, shoulder no cover), abdomen (sleeveless, back, buttocks without coverage), basically covers the existing types of pregnant women's radiation protection clothing.

At the same time, it has purchased 2 special labor protection measures.

They are radiation proof gowns and

。

The test results show that the radiation proof clothing samples generally have good shielding effect on the widely used power frequency alternating electric field (50Hz) in most daily life. Most samples have obvious shielding effect on 2.45GHz electromagnetic waves, but the shielding effect of electromagnetic waves in the range of 100MHz to 2.45GHz is low.

Influence

The main factor of shielding effectiveness is clothing style.

On the whole, the smaller the length of the opening, the longer the length of the garment, the better the shielding effectiveness.

The neckline, the lower pendulum, the cuff and the pants of the special labor protection clothing are all closed, and the length of the coat is long, so it has a better shielding effect on the electromagnetic wave.

The protective effect of the belly pocket on the electromagnetic wave incident on the front is better, but it has no effect on the electromagnetic wave incident on the back side. Therefore, it is only applicable to the environment where the electromagnetic radiation source is needed.

Longer

Better protection for the abdomen.

However, for the convenience of wearing, the existing pregnant women's radiation protection clothing products often use a low neckline and a large style under the armpit opening, and the hem of the garment is usually high, so it is difficult to achieve good protection for the chest and lower abdomen.

Washing has a more complicated function on clothing. On the whole, most samples have higher shielding effectiveness than manual washing after washing. Washing by one time (machine wash and hand washing) does not significantly reduce the electromagnetic wave protection ability.

City Consumers Association suggests that consumers should be scientific and rational in the face of electromagnetic radiation.

In daily life, computers, cell phones, microwave ovens, refrigerators and other household appliances, as well as electrical lines and communication base stations will produce certain electromagnetic radiation.

At present, there are relevant safety standards for electromagnetic waves in the environment.

The key to the effect of electromagnetic radiation on pregnant women and fetus is the exposure time and intensity. The electromagnetic radiation exposed by pregnant women mainly comes from the TV, computers and mobile phones and household appliances commonly used in life. The state has strict requirements for the electromagnetic radiation of these household appliances and communication products, and the electromagnetic radiation of the qualified products is safe for the human body.

However, in some specific areas, such as computer rooms, hospitals, instrument rooms, etc., where electronic circuits are distributed densely, or testing institutions prove that there are higher energy electromagnetic waves in the environment, it is recommended to use better shielding effectiveness if necessary.

Products are properly protected.
