The Effect Of Radiation Proof Clothing Is Questioned.

In January this year, Ms. Lin bought a brand of radiation protection maternity dress priced at 454 yuan at a shopping mall at Hou Bin Road.

In order to verify the effectiveness of the clothes, the salesperson asked her to wrap her cell phone in the radiation proof maternity dress. After half a minute, she was asked to call her friend who accompanied her to buy clothes. The voice in the receiver suggested that the cell phone was not in the service area.

"The signal of the cell phone is blocked by clothing," the salesperson said, even if the clothes that could not completely block the signal could also weaken the signal, depending on the fabric of the clothes.

However, Ms. Lin went home and then tested the instructions, but found that there was still a faint signal on the phone.

She therefore thought that clothes did not have the effect of radiation protection.

Ms. Zhuang also bought a radiation protection maternity dress two months ago. It also found that clothes could not block the radiation from mobile phones.

Since there was no reservation, the business department could only ask her to negotiate with the merchant or to make up the bill after receiving the information from her.

Survey: there are many ways to test results.

The reporter recently visited several urban women's and infant products stores, and found that the price of radiation proof maternity dress was far from 2000 yuan to 100 yuan, while almost every brand claimed that the shielding effect of its products was more than 99.9%.

During the interview, the reporters found different brands of radiation protection maternity checks.

In addition to the most commonly used "cell phone detection method", some businesses use a small instrument plus an electric pen to make a test presentation.

In a women's and children's shop near Ruijing, the salesman showed the instrument to the reporter: the radiation protection clothing was between the detector and the electric pen, and the electric pen didn't respond, and when the other ordinary clothes were replaced, the electric pen lit up.

The salesman explained that the red light was not lit because the radiation protection clothing blocked the rays.

In addition, many businesses also hyped up their sales of radiation proof clothing containing metal components, claiming that the higher the wire content, the stronger the radiation protection capability.

Experts: ordinary metals can.

Screen cell phone signal

"At present, the national standards for testing methods of radiation protection clothing have not yet been published.

Such clothing testing is based on the enterprise's production standards.

Yesterday, relevant experts of quality inspection department of our city told reporters.

"Ordinary metals have the function of shielding cell phone signals, placing them in barbed wire or iron cans, and mobile phone signals will be shielded."

Experts said that the mobile phone signal is strong and weak, the pmission power is also different, it is difficult to explain the effectiveness of the test results.

The effectiveness of the metal fiber contained in the radiation proof maternity dress fabric is also checked by scientific methods.

Reporters also learned in the interview that in December 1, 2009, the state formally promulgated and implemented the national standards for radiation protection knitwear, protective clothing and microwave protective clothing.

Among them, the shielding standards of radiation proof knitwear are 99.9%, 99% and 95%, respectively. There is another standard which is divided into three categories: A, B and C. The relationship between them is that class a can shield 50 dB electromagnetic radiation, equivalent to 99.99% of the radiation protection rate, B class can shield 30 dB electromagnetic radiation, equal to the radiation protection rate of 99.9%, and C class can shield 10 dB electromagnetic radiation, which is equivalent to the radiation protection rate reaching 90%.

As long as the radiation proof clothing produced after December 1, 2009 is produced, the two radiation protection energy efficiency standards will be marked on the production labels. When consumers choose to buy them, they can choose carefully as a standard and ask the sellers for qualified inspection reports issued by inspection bodies with inspection qualification.

The most effective way to prevent radiation

Less exposure to radiation sources

Quality inspection experts said yesterday that the maternity dress must choose a reliable quality, in addition to the identification of radiation efficiency standards, the purchase should also pay attention to cloth safety.

Do not choose bright color, pungent style, unqualified cloth, inferior dyestuff and formaldehyde excessive clothing will cause certain harm to the body of pregnant woman.

In addition, there are many kinds of radiation known at present, with different wavelengths, and electromagnetic radiation such as cell phones is only part of it.

Consumers should never assume that wearing radiation proof clothing is safe. The safest and effective way to prevent radiation is to get less exposure to radiation sources in daily life.
