Dr. Cheng Aiping at Zhejiang Provincial People's Hospital suggests that people should not use computers or mobile phones for long periods. She also recommends washing one's face after using a computer, and keeping fresh air circulating inside a room. "These measures are far more important than wearing a radiation suit," said Cheng.

Chen Feng, a scientist from a laboratory recommended by the Chinese Academy of Sciences to conduct the experiments, said the garments proved effective in blocking 90 percent of electromagnetic waves coming from in front of the body -- from computers, for example -- but failed to protect people from radiation from any other direction.

"When the electromagnetic waves get inside the garment from other directions, there would be no outlets for them to be dispersed. You are actually exposed to a higher level of radiation influence (compared to others who don't wear such clothes)," Chen told the TV program.

However, in contrast to these findings, many maternity clothing producers claim their products are able to block 99.99 percent of radiation waves from electronic devices.

Despite decade-long growth and a prosperous market, China currently has no industry standard for such so-called protective clothing.

浙江省人民醫院的程愛萍醫生建議準媽媽，打手機和用電腦的時間不要過長；使用電腦后，要及時用清水洗臉；要注意室內通風。她說：“這些措施比穿防輻射服更重要。”

本次負責防護服檢測的實驗室是由中科院所推薦的。該實驗室的工程師陳峰表示，實驗證明，如果電腦等輻射源處于身體正前方，那么防輻射服能夠有效屏蔽90%的電磁輻射；然而，對于來自其他方向的輻射，防輻射服卻起不到良好的防護作用。

陳峰在央視節目中介紹說：“當電磁輻射由其他方向進入防護服內，輻射波無法反射出去；于是（與不穿防護服的人相比），穿著防輻射服的人反而會受到更高強度的電磁輻射。”

然而，商家的說法卻截然不同。許多孕婦服制造商宣稱，他們的產品能夠抵擋99.99%的電子產品輻射。

這些所謂的防護服已經存在了近十年，市場需求也很大；盡管如此，我國目前還沒有出臺相關的行業標準。
