Radiation Protection Experiment Controversy: 60 Companies Jointly Re-inspected

Meng Yanfeng

The cold winter in Beijing made Tian Kai feel cold, but it was less than the chill that was brought about by the recent radiation protection apparel industry. As the chief operating officer of Shanghai Yindun Textile Technology Co., Ltd., his job in recent days was to answer the phone at a high frequency. From the media to the enterprise, there was only one topic to ask: About the December 17th CCTV Truth Survey on pregnant women Reports on whether radiation suits are useful or not.

People who mention silver shield textiles may be unfamiliar, but their radiation protection brand “Youjia” is well-known to many consumers. On December 17th, CCTV invited an electronic testing laboratory to inspect pregnant women's radiation suits. The results showed that pregnant women's radiation suits actually had more than 90% shielding effect from radiation sources in a single direction, but in real life Sources of electromagnetic radiation from different directions, radiation protection suits not only do not play a protective role, but will make the radiation intensity in radiation suits become greater.

It is such a survey report that Tian Kai has experienced an unprecedented crisis.

“CCTV's investigation and experimental results are one-sided. Our entire industry has doubts about this report. As a media with great influence, we believe that its investigation should be authoritative, but unfortunately, this survey is very inaccurate and the experiments are flawed. "Tian Kai voice is urgent.

The same attitude with Tian Kai is also the strategic director Wei Da of Shanghai October Mommy. "The experiment conducted by CCTV was too one-sided, and even some of it was taken out of context and not rigorous enough," he said.

The question of the enterprise
The coverage of the Chinese authoritative testing organization recommended by the Chinese Academy of Sciences as a "Laboratory for the Rohde & Schwarz Companies" (CCTV) made us unprepared. According to Tian Kai, there was a friend of a small business on the night of the 17th. Call to ask what to do. “CCTV’s report was on the evening of the 17th. On the 18th, more than 60 manufacturers opened an industry conference in Shanghai, including radiation protection clothing brands such as UPlus, October Mommy and Chini. What should we do to discuss this matter? ."

"Already there are consumers calling to consult, there are also returns, we will try to explain, if we insist on returning we will handle it." Tian Kai further said that the current corporate sales have been affected.

“This is definitely an impact on the industry. The freezing period of the three months of the industry can not be avoided, and many small businesses are even closed for this purpose.” Tian Kai is very sure, “We also raised several questions internally about this report, including the authority of the experimental institution. Sex and the motive behind it all make us puzzled.”

According to Tian Kai, the domestic authoritative testing institute recommended by the Chinese Academy of Sciences of CCTV in the program is actually a corporate laboratory of the “Rode and Schwarz Company”. “We called in the past today. The front desk of the company is very straightforward to say that CCTV programs are experiments on radiation protection suits. But is such a laboratory qualified? Is it recommended by the Chinese Academy of Sciences? Is the Chinese Academy of Sciences unable to do this? Experiment? This company is actually a mobile service operator, and we really don't know what the Central Party is looking for such a lab."

If the authoritativeness of the laboratory is one of the questions, the practice of the experiment also makes the radiation-protective clothing company puzzled. “The laboratory environment is not a standard laboratory for the detection of electromagnetic radiation. Not to mention that their test equipment is a directional acceptance device. It is not a multi-directional test result. The experimental transmission antenna is placed directly above the signal receiving device. This electromagnetic wave is emitted in daily life. There is basically no existence. This is a false proposition!” Tian Kai questioned.

The retired senior engineer Li Guodong of the Shanghai Testing Center under the Shanghai Measurement and Measurement Technology Research Institute also did not approve CCTV's experimental results. “The inspection methods requested by CCTV are not scientific. Before I retired, I had been doing research on electromagnetic radiation at the Shanghai Testing Center. The test environment of this experiment was problematic, so the results were subject to verification.”

At present, several major anti-radiation brands such as Yujia and October Mommy have joined other nearly 60 industrial enterprises to send samples to Shanghai Metrology and Measurement Technology Research Institute, East China National Metrology and Measurement Center and China Shanghai Testing Center for joint testing. The test results will be drawn on December 20.

Lack of industry standards

Radiation protection has been questioned as to its radiation protection effect since the military began to transfer to civilians in the 1990s. “We will definitely defend our rights on this matter. The specific form and degree will be based on the test results.” Tian Kai is very sure. "Do not rule out urging the association to join forces with other companies in collective protection."

According to Wei Da, radiation protection suits started from the military in the 1990s and have been used by the military until after they were converted into civilian use. “It will be questioned almost every two years! But this time there was no real interview with our company and the real experts in the industry.”

Tian Kai said that the questioning interval is even used once a year. "But our sales are getting bigger and bigger. This is more convincing than our explanation."

According to Tian Kai, the entire radiation protection apparel industry can be said to have more than sixty companies with brand names, and annual sales are about 5 billion. “Tianxiang, Youjia, October Mommy, Chini, and Tingmei should be ranked in the top five, but the specific ranking cannot be determined. The sales of these five companies should account for 60% of the entire industry.”

Most of the headaches for Tian Kai and Wei Da are that there are currently no industry standards. “We started to promote standards development from the previous year, and also established the National Electromagnetic Shielding Materials Standardization Technical Committee. The sponsors include colleges, experts, clothing companies, fabric companies and many other companies. There are many companies such as Youka, Chini, and 3M. The purpose is to really have a national approved radiation protection clothing industry standard introduced, this clothing standard should be able to come out in the first half of next year, I believe that with this standard will make the industry healthier."

"This is also a good thing! The arrival of winter means that spring is approaching. We do not think that such an 'experimental trap' can shrink the industry. We wait for the experimental results and do rights protection again," said Tian Kai.
