Bob:

Could you put this out on RadSafe for me, I'm not subscribed anymore.

To confuse the matter even more, the actual article in Environmental 
Health Perspectives does not bear much resemblance to the press 
release.

1) The article does not report actual evidence for tumor promotion. 
It reports that exposure of leukemia cells in cell culture to 5-100 
microT (50-1000 mG) fields inhibited chemically-induced 
differentiation is "a manner similar to that of a chemical tumor 
promoter".

2) The field intensities used to induce the differentiation effect 
are an order of magnitude higher than those commonly encountered in 
the environment.

3)  A previously-published study of the same endpoint in the same 
system (Revoltella et al., 1993) found no evidence for the effect at 
200 microT (2000 mG).

4)  The effects on proliferation of the leukemia cells were found at 
100 and 1000 microT (1000 and 10,000 mG), and these results are 
contradicted by numerous previously-published studies.

5)  The data on "turning genes on" comes from an entirely separate 
set of studies by a different group; data which has failed numerous 
attempts at replication.

So they have found an "effect" that no one else has been able to 
found any evidence for, that might be related to carcinogenesis, and 
that requires field intensities at lease 10X above environmental 
levels.
