Hi everybody:

We are getting considerable response to Ed Maxey's message about Sunbeam's
efforts to deal with the EMF health hazards by cancelling out the
_magnetic field_ (MF).  I cannot send all of them, but I believe that 
Alasdair's note below touches upon THE important point.....  We are not
being confronted by JUST the magnetic field (MF) -- though that is pretty
much ALL that science has investigated, so far.

In addition to the following, I am going to send two more messages about
this.  (1)  An "off-group" discussion I have been having with Marjorie
Lundquist...., and (2) I intend to go back into my files and send you
(again) my "footnote" message (6 or 8 months back, to a draft report
written by the NIEHS drafters on the EMF RAPID study) which (I believe)
succinctly describes the nature of the problem ... and incidentally (in part)
explains "why" so much of the research -- focusing only on the MF -- is
falling far short of what it claims to have found.....  In particular, the
two recent NCI studies (by Linet) are examples of claims which are not
justified by electric field (and transients and harmonics) "reality".....

Cheerio.....

P.S.  I'm sorry there are so many messages on this, but it IS
important.....

Dear Roy & everyone

The Sunbeam blanket would only probably be "safe" if they also
added earthing layers or screen (connected to ground or an earthed
neutral) to remove the E-field.  Please see my email of 23 March
regarding E-fields and the recently released NCI appliance
study....... (it was a response to FLASH!!! New NCI (childhood)..
