Those bursts have other effects also:

"However, researchers at the Swedish National Institute for Working
Life said they looked at the mobile phone use of 905 people between the
age of 20 and 80 who had been diagnosed with a malignant brain tumor
and found a link.
"A total 85 of these 905 cases were so-called high users of mobile
phones, that is they began early to use mobile and, or wireless
telephones and used them a lot," the study said.

"The study also shows that the rise in risk is noticeable for tumors on
the side of the head where the phone was said to be used," it added.
Kjell Mild, who led the study, said the figures meant that heavy users
of mobile phones, for instance of who make mobile phone calls for 2,000
hours or more in their life, had a 240 percent increased risk for a
malignant tumor on the side of the head the phone is used.
"The way to get the risk down is to use handsfree," he told Reuters.

He said his study was the biggest yet to look at long-term users of the
wireless phone, which has been around in Sweden in a portable form
since 1984, longer than in many other countries."
