Thanks Anth. I do feel like I am in a rat race now and then. My cell
phone is very convenient and handy, but I do wonder about the long
term effects of the microwave radiation even if it is only a low dose.

I am assuming that even the debunkers in the group are willing to
admit that microwave radiation causes cancer the same as X-rays are
known to cause cancer.

Actually, no. Microwaves could not possibly cause cancer in the same
manner as X-rays.

X-rays can cause cancer because it is ionizing radiation: it can
physically damage and destroy molecules by breaking chemical bonds.
When this molecule is DNA, and the damage is to a very specific part
of the copying/repair mechanism, you might get a cancer cell.

Microwave radiation, by contrast, is not nearly energetic enough to
damage DNA in such a manner. It could damage the DNA by heat production
(like in a microwave oven), but that would probably kill the cell in the
process. (And I'd think you'd notice your head cooking in the meantime.)

This is not to say there is not another mechanism by which microwave
radiation could cause cancer, or any number of mechanisms by which
microwave exposure might lead to cancer, but not the same as X-rays
do.

I think this is the full article that this one refers to:

http://ehpnet1.niehs.nih.gov/members/2003/6039/6039.html

The authors admit that they have a small number of animals (4 in each test
group) and that the maximum occurance of dark neurones is ~2% of the
neurones they saw in the slices, although in some restricted areas they
dominated the picture. However, that is a given and the significance of this
finding depends on the size of the restricted areas.

These findings are in contradiction with findings by this group:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11523936&dopt=Abstract

They used mice, 10 in each group and found no significant occurance of
albumin leakage into the brain. An important difference is that they exposed
the mice for 1 hour, rather than the two hours of exposure used by the Lund
group.

This group:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=9386779&dopt=Abstract

Also used rats, which were irradiated for four hours. They did find some
leakage of albumin, but found that no histological injury was found and that
the leakage of albumin was reversable. They concluded that the changes to
the BBB were modest at worst and that GSM irradiation (900MHz band)) is
"unlikely to produce pathologically significant changes of the blood-brain
barrier permeability".

There have been more studies but the only one that claimed significant
results is the Lund study.

So, I think the Lund group's finding need to be replicated using a greater
number of animals, and also using a different scoring system. Their scoring
system uses only three groups: none, modest and severe. The problem with
that is that it's quite subjective and they didn't adress this problem by
showing e.g. inter observer variability of slice appreciation.

Had you taken the time to actually look the study, and others like it, up;
you'd have seen that the worry hasnothing to do with cancer, X-ray
irradiation or the likes. The worry is that perhaps GSM fields can change
the permeability of the BBB, signified by albumin leakage into the brain. If
that is the case then it would be a reasonable assumption that with albumin
also other, toxic, substances may cross the BBB.

We have a lawsuit coming up this month in Oak Park from a group of
parents who have filed a CA suit against the school district claiming
that the WiFi networks in the schools have the possibility of damage to
the BBB in the students.

They have no injured party for evidence.
The district has followed any and all local, state and federal regs.
They claim some 400 "reports" (none confirming the results of any other
but say that doesn't matter at all in the least. You know, the
scientific method is out the window).

The last study they report was from I think from Sweden, and placed rats
in a faraday cage with an emitter in the center. Then subjected the rats
to 10, 100 and 1000mw of RF, far more than ANY WiFi network is capable
of emitting, btw but that doesn't matter to them either.

So we'll see.
