California Government On the Dangers of Cellphones (cbslocal.com)
mi quotes a report from CBS Local: After keeping it hidden for years, California's Department of Public Health has released a draft document outlining health officials' concerns about cellphone radiation exposure. The previously unpublished document was released this week after a judge indicated she would order the documents be disclosed. Health officials' overall recommendation is to "increase the distance between you and your phone" by using a headset, the speaker phone function and text messaging. Health officials recommend not sleeping near your phone and not carry it in your pocket or directly on your body, unless it is off. The fact sheet also states that "EMFs can pass deeper into a child's brain than and adult's" so suggests parents limit their child's cellphone use to texting, important call and emergencies.
The document was unreleased because it was a factually wrong draft. A corded phone produces a weaker EMF than a wired headset? Really?
Moderating "-1, Disagree" is simple censorship. Have the guts to post your opinion.
Your head receives less than 10^-12W at 850MHz from the sun [1]. Your phone delivers probably 0.5W. So if you scaled the sun to match microwave radiation levels, then no, you'd be fried in a millisecond. B-)

Cell Phones and Cancer Fact Sheet
"Exposure to ionizing radiation, such as from x-rays, is known to increase the risk of cancer. However, although many studies have examined the potential health effects of non-ionizing radiation from radar, microwave ovens, cell phones, and other sources, there is currently no consistent evidence that non-ionizing radiation increases cancer risk (1).
"The only consistently recognized biological effect of radiofrequency energy is heating. The ability of microwave ovens to heat food is one example of this effect of radiofrequency energy. Radiofrequency exposure from cell phone use does cause heating to the area of the body where a cell phone or other device is held (ear, head, etc.). However, it is not sufficient to measurably increase body temperature, and there are no other clearly established effects on the body from radiofrequency energy."

The referenced draft document simply states that IF you are concerned about it, here's how to reduce exposure. It doesn't state that RF exposure is dangerous.
In fact the National Cancer Institute says the opposite:
What the study showed: No association was observed between cell phone use and the incidence of glioma, meningioma, or acoustic neuroma, even among people who had been cell phone subscribers for 13 or more years
How do you know that heat and ionization are the only ways RF radiation can harm a brain?
It's well known that exposure to UV increases the risk of skin cancer. Is that heating or ionization?
That would fall under ionization
