Then why is that all major cell phone makers, including Nokia, are against disclosing
independently verified radiation levels produced by their phones?
Ok, you truly believe because there is a little piece of metal between you and the cell, you are protected by any potentially dangerous rays. Well, have a look at
this German site disclosing SAR (Specific Absorption Rate) levels of various phones. Please keep in mind that those numbers are not independently verified, but come from the manufactor.
- the Sony Ericsson Z600 has a SAR level of 0.16.
- the
Palm Treo 600 has a SAR level of
1.53 (!).
Note that in Europe, the
maximum allowed SAR level is 2.00. Recommended is a level of below or equal 0.60. In other words, according to palmOne's own numbers, the Treo is more than twice above the limit of what is recommended in Europe. And, it is radiating 9-10x more than the Sony Ericsson. Perhaps the "protecting" metal piece you were talking about got a little rusty for the Treo.
While I agree that there has been no 100% medical evidence suggesting that radiation from mobile phones might cause cancer or other health problems, at the same time, there’s no definitive proof that cell phone radiation is harmless. Most research on radio frequency energy has focused on short-term exposure of the entire body. It will be many more years before a definitive conclusion can be reached on whether mobile phone emissions pose any risk to human health. Until then, I rather stay cautious and carefully follow every study that is being made, than to solely listen to those cooperations whose primary goal is to satisfy their shareholders by selling more phones.
