【科普】手机辐射对健康的影响问题亟需明确
WASHINGTON (Reuters) - Researchers should study more children and pregnant women in trying to figure out if cell phones or other wireless devices could damage health, the U.S. National Research Council advised on Thursday.
A few studies have indicated a possible link between mobile telephone use and brain tumors, although far more show no connection. But because wireless devices have become almost ubiquitous, researchers wants to ensure their safety.
The U.S. Food and Drug Administration asked the National Research Council to recommend some future lines of study. The Council, which advises Congress and the federal government on scientific matters, held a meeting of experts including engineers and biologists and has now released the full report.
Most studies have looked only at short-term effects on healthy adults, the report said.
More study needs to be done on multiple, long-term, low-intensity radiofrequency (RF) exposure, the report said.
"Measuring the amount of RF energy received by juveniles, children, pregnant women, and fetuses from wireless devices and RF base station antennas could help define exposure ranges for various populations," the council said in a statement.
"Although it is unknown whether children are more susceptible to RF exposure, they may be at increased risk because of their developing organ and tissue systems," it added.
"Additionally, Specific Absorption Rates for children are likely to be higher than for adults, because exposure wavelength is closer to the whole-body resonance frequency for shorter individuals."
The report also notes that children today will experience a longer period of RF field exposure from mobile phones than adults, because they will most likely start using them at an early age.
Researchers should also analyze the different types of antennas for the amount of RF energy they deliver to different parts of the body.

WASHINGTON (Reuters) - Researchers should study more children and pregnant women in trying to figure out if cell phones or other wireless devices could damage health, the U.S. National Research Council advised on Thursday.
华盛顿（路透社）报道：星期四，美国国家研究委员会建议，研究人员应该更多的研究儿童与孕妇，从而设法弄清手机或者其它无线电装置是否会损害健康。
A few studies have indicated a possible link between mobile telephone use and brain tumors, although far more show no connection. But because wireless devices have become almost ubiquitous, researchers wants to ensure their safety.
一些研究指出，使用手机和脑肿瘤之间可能存在关系，尽管更多的研究表明二者之间没有联系。但是由于无线电装置已经普遍存在，研究人员希望确定它们的安全性。
The U.S. Food and Drug Administration asked the National Research Council to recommend some future lines of study. The Council, which advises Congress and the federal government on scientific matters, held a meeting of experts including engineers and biologists and has now released the full report.
美国FDA要求国家研究委员会推荐一些未来的研究。该委员会在科学事务上为国会和联邦政府提供建议，并已经举办了包括工程师和生物学家在内的专家会议。会议的完整报告已发布。
Most studies have looked only at short-term effects on healthy adults, the report said.
报告指出，大多数的研究仅仅关注对于健康成人的短期影响。
More study needs to be done on multiple, long-term, low-intensity radiofrequency (RF) exposure, the report said.
报告指出，对于复杂的，长时间的，低频率的无线电暴露应该给予更多的研究。
"Measuring the amount of RF energy received by juveniles, children, pregnant women, and fetuses from wireless devices and RF base station antennas could help define exposure ranges for various populations," the council said in a statement.
委员会在报告中说：“对于儿童、孕妇及胎儿从无线电装置和无线电基站天线所接收的能量总和的测量对于定义多种人群的无线电暴露范围有帮助。“
"Although it is unknown whether children are more susceptible to RF exposure, they may be at increased risk because of their developing organ and tissue systems," it added.
报告还指出，儿童是否对无线电暴露是否更加敏感仍然不清楚，这对于它们发育的器官和组织来说是不断增加的风险。
"Additionally, Specific Absorption Rates for children are likely to be higher than for adults, because exposure wavelength is closer to the whole-body resonance frequency for shorter individuals."
