Radiation proof pregnant suit is a lie 孕婦防輻射服竟為騙局
In the past few years, a new trend has been gaining popularity in China: pregnant women should wear radiation-proof clothes once they have a baby. However, scientists said these suits could be doing more harm than good.
近年來,在中國國內,孕婦們穿防輻射服的趨勢蔚然成風。然而,科學家表示,穿著這些防護服有時候弊大於利。A separate experiment showed that a radiation-proof suit only protects you where you're covered, so radiation can still reach the body via the ends of sleeves, neckline, etc.
一項獨立的實驗證實,防輻射服只能保護覆蓋住的身體部位,而輻射波仍然會從衣服的袖口、領口等縫隙射入。
The radiation that can squeezes inside the radiation clothes gets trapped inside, accelerating absorption through the skin. Like a greenhouse, the intensity of the radiation underneath the clothes is thus increased as radiation waves bounce back and forth between skin and clothing. Without these radiation clothes, normal skin can actually reflect most radiation away from the body, absorbing only a small amount.
由縫隙進入防護服內部的輻射波無法反射出去,就會更快地被面板所吸收。這就像溫室的原理一樣,輻射波在面板和防輻射服之間進行多次反射後交會疊加,反而增大了防護服內的輻射強度。而如果不穿防護服,正常情況下,人的面板能夠將大部分的輻射都反射出去,只有很小的劑量會被人體吸收。Dr. Chen Qingsong, an expert on electromagnetic radiation at Guangdong Prevision and Treatment Center for Occupational Hygiene, said that electromagnetic radiation that is seen in our daily lives has a very small impact on human health.
廣東省職業病防治院的陳青松博士是研究電磁輻射方面的專家。他介紹說,日常生活中的電磁輻射對人體的影響是微乎其微的。"National standards for electromagnetic radiation from home appliances has been set up in 1988 with a top limit of 12 volt/meter, which is far less than a western standard," said Chen. "If a TV, a computer, a micro-wave oven and a hairdryer are turned on at the same time, their combined radiation is still harmless to human health."
陳青松說:“我國在1988年就制定了家用電器的電磁輻射標準,規定的上限為12伏每米,遠低於歐美等國家的標準。無論是電腦、電視、微波爐,還是電吹風,即使把它們全開了,疊加起來的電磁輻射對人體也不會構成傷害。”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.
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;使用電腦後,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。”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.
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於身體正前方,那麼防輻射服能夠有效遮蔽90%的電磁輻射;然而,對於來自其他方向的輻射,防輻射服卻起不到良好的防護作用。"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.
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;於是(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。”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.
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。Despite decade-long growth and a prosperous market, China currently has no industry standard for such so-called protective clothing.
這些所謂的防護服已經存在了近十年,市場需求也很大;儘管如此,我國目前還沒有出臺相關的行業標準。
