Again new study that may trigger another debate whether cellphone's radiation is dangerous enough for consumer in long term or not. A team headed by Dr. Elizabeth Cardis, concludes that there's 18% increase in brain tumor development with long-term cellphone usage. Does anyone care anyway about this study?
While I am still skeptical about these kind of studies, those who does care may need to use a new device called SAR Shield. This thing, which can be attached to a phone, is claimed to reduce harmful radiation waves up to 89%. To be more convincing, SAR Shield is the only FCC-approved device in this area.
Anyway, let's take a look at displayed table about highest and lowest radiating cellphones in term of SAR rating (measured in watts/kg). We can find out that among top 20 highest radiating cellphones, Motorola quite dominates the chart by taking all top 3 list. Among the list also popular devices like BlackBerry Curve 8330, BlackBerry Bold, and Motorola Droid.
In other hand, Samsung is recognized as more green-friendly in term of radiation. In 20 lowest radiating cellphones list, only 4 are not from Samsung. What about our popular iPhone series? Thankfully, not yet in the list. Also among 3 iPhone series, iPhone 3GS has the less amount of radiation.
Again, I doubt these lists will likely change consumerism against popular gadgets.
