Cell phone radiation

Drudge links to an interesting news report on a recent study which demonstrates slowed reaction times from cell phone radiation. The report is a little bit misleading, in that the actual paper does not say people were having a conversation while tested for reaction times and memory recall; they were only being exposed to the cellphone (a Nokia 6110) radiation. The dosage was eqivalent to a 30 minute phone call.

This part was cool (from the paper -- not the news report.):

Interestingly, Huber et al., 2002 and Huber et al., 2005 observed an increase in relative regional cerebral blood flow (rCBF) in the dorsolateral prefrontal cortex ipsilateral to 30 min pulse modulated RFR from a 900 MHz DMP. Such a finding implicates that blood flow changes caused by RFR may underlie some of the cognitive changes that have been observed with DMP RFR, given that the prefrontal cortex plays a major role in working memory.

The paper passes muster to my scientific reading of it; it's not guilty of a selection bias like some of those crappy Swedish papers that purport to show cell phone use causes Acoustic Neuroma tumors.
