radiation Americans absorb when they talk on their cell phones.Now, amid the Christmas sales rush, manufacturers are revealing for the first time the radiation levels of nearly every phone sold to consumers so infatuated with the gadgets they use them when they walk, drive, even eat.It is a...
or SAR, of every handset that we review. Though we're still reformatting our full Cell Phone Radiation Charts and will bring them back shortly, we have updated our lists of the 20 phones with the lowest SAR levels and the20 phones with highest SAR levels. ...
CNET presents the five phones with the highest radiation. The FCC mandates that all cell phones must be tested for their specific absorption rate (SAR) – the rate of which radiation from the phone is absorbed into your body. The maximum level that the FCC allows is 1.6 watts/kg of flesh...
The rats were exposed to "carefully calibrated radiofrequency (RF) radiation levels designed to roughly emulate what humans with heavy cell phone use or exposure could theoretically experience in their daily lives," said Maron. Exposure involved their whole bodies with radiation for approximately nine ...
cell phone orcell·phone(sĕl′fōn′) n. A portable telephone that sends and receives radio signals through a network of short-range transmitters located in overlapping cells throughout a region, with a central station making connections to regular telephone lines. Also calledcellular telephone,mo...
根据第一段中的Teenagers who talk on the cell phone a lot, and hold their phones up to their right ears, score worse on one type of memory test. That’s the finding of a new study. That memory impairment might be one side effect of the radiation (放射线) that phones use to keep ...
Short-term exposure to cell phone levels of radio frequency radiation do not appear to to influence semen parameters in vitro 来自 学术范 喜欢 0 阅读量: 20 作者:A Van-Gheem,J Martin,L Penrose,N Farooqi,S Prien 摘要: Conservation is about protecting and nurturing species so that they can...
(See also:CNET's Quick Guide: Cell phone radiation levels.) SAR, in short, is the rate at which your whole body absorbs energy from a radio-frequency magnetic field. It's measured in watts per kilogram or W/kg. And it's typically averaged either over the whole body or over a small...
"In our studies, rats and mice received radio frequency radiation across their whole bodies. By contrast, people are mostly exposed in specific local tissues close to where they hold the phone. In addition, the exposure levels and durations in our studies were greater than what people experience...
Inveterate cell-phone addicts may feel that the devices help them to work smarter and -- surprisingly -- they may be right. If they're mice, that is.
