Q. for Dr. Z. or anyone else who may have the necessary expertise: Is there any way for a subject to use a cell phone while undergoing a cranial MRI? For that matter, is there any type or frequency of EM radiation that a cell phone produces which is more powerful than that which would be experienced by a person undergoing a MRI of his/her brain? If not, how could any effects be definitively attributed to the cell phone radiation? well - your cell phone would immediately be sucked up against the magnet unless you held on tight. I am not sure if it could work at all (mine sure doesn't when I am in the MR suite). If it did work it would probably mess with the MR signal which is after all a radiofrequency signal. >Stough said further, as-yet-unpublished, research by his team suggested >the impact of mobile phone radiation on the brain was cumulative. > >"People, for instance, who use the mobile phone a lot seem to have more >of an impairment than people who are more naive users," he said. Once again cumulative effects have to be looked at carefully since the brain (and any other tissues) will recover from insults. I am just very skeptical of all this. The radiation from a cell phone is very weak and it has to penetrate the skin skull (some of us have thicker skulls than others). Another technology - Magneto-encephalogy (MRC) a sort of suped up localized EEG might be a better way to look at this.
As I have (only semi-humorously) mentioned previously, people who yap constantly on any type of phone seem to have some sort of "impairment" which does not necessarily seem to have anything to do with radiation . . . (Which is why 90+% of the time I let my landline go directly to the answering machine, since experience shows that about 90% of the calls are from telemarketers or similar nuisances, and about 90% of those are pre-recorded or computer-generated messages. As I would tell a live telemarketer if one ever called and I happened to pick up, "I don't pay $XX a month for a phone line because I don't get enough unwanted advertising from people trying to get me to send them money from TV, radio, the newspaper, magazines, billboards . . . ) >However, he stressed that the impact on brain function was small and >the study did not find that mobile phones caused a health problem. > >"We haven't established that there's negative health consequences -- >that's a different type of study," he said. > >"We're just showing that the radiation is actually active on the brain. >But the impairment is small. The convenience and the way that we >communicate now these days outweighs that effect." Perhaps I missed something, but it sounds like what they did was compare people who were talking on an active phone for 30 minutes with people talking on a dummy phone for 30 minutes and concluded that it was the radiation from the active phone which caused a difference. To conclude that it is actually the radiation, istm that they need to conduct an experiment where one group is bombarded by equivalent radiation for 30 minutes while doing something other than trying to carry on a phone conversation (or doing absolutely nothing) versus a control group which does the same thing (or the same nothing) for 30 minutes while not being bombarded by radiation. Or compare people talking on a landline for 30 minutes with people not talking on any kind of phone, as istm that the more likely reason people using a cell phone for 30 minutes show psychological changes is that they get involved in the conversation to the expense of paying attention to whatever is going on around them. >------ >"In Japan, rape is how you say hello.
