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.

浙江省人民医院的程爱萍医生建议准妈妈，打手机和用电脑的时间不要过长；使用电脑后，要及时用清水洗脸；要注意室内通风。她说：“这些措施比穿防辐射服更重要。”

本次负责防护服检测的实验室是由中科院所推荐的。该实验室的工程师陈峰表示，实验证明，如果电脑等辐射源处于身体正前方，那么防辐射服能够有效屏蔽90%的电磁辐射；然而，对于来自其他方向的辐射，防辐射服却起不到良好的防护作用。

陈峰在央视节目中介绍说：“当电磁辐射由其他方向进入防护服内，辐射波无法反射出去；于是（与不穿防护服的人相比），穿着防辐射服的人反而会受到更高强度的电磁辐射。”

然而，商家的说法却截然不同。许多孕妇服制造商宣称，他们的产品能够抵挡99.99%的电子产品辐射。

这些所谓的防护服已经存在了近十年，市场需求也很大；尽管如此，我国目前还没有出台相关的行业标准。
