.........Response from Dr. Cherry......

He says the double exposure calculation is off by half....  i.e., It
SHOULD BE FOUR TIMES!!!..... He's probably right....  Any more argument?
Clas, Alasdair, Bill, et. al.........guru......
(Now, consider what happens when the NEXT pair of antennae are added???)

Dear Roy,

As we know the power density (microwatts/sq cm) is a function of the square 
of the electric field (S = E^2/3.77) where E is the electric field in V/m. 
 i.e. E = 10 V/m converts to S = 100/3.77 = 26.5 microwatts/sq cm. I 
understand that the fields are additive. This would mean that rather than 
adding two equal signals of 26.5 microwatts/sq cm (giving 53 microwatts/sq 
cm) instead we add the two E fields, i.e. 10 + 10 = 20 V/m. This then 
becomes S = 400/3.77 = 106.1 microwatts/sq cm (4 times the power density).

Can any of our engineering experts confirm or correct this ?

Regards
Neil Cherry

............From EMF-L........

Yes, it very likely will double the exposure (approximately).....   P.S.
There will likely
be MORE to follow........


That is probably the REAL problem with these towers -- not the first
lonely antenna
that is mounted.....   But those that follow.......  Is that right,
Sutro Tower????.....guru....

 DEAR ROY, SPRINT PCS ERECTED A CELL TOWER IN 1998 LESS THAN 100' FROM
MY HOME. WE TRIED IN VAIN TO HAVE IT STOPPEDBUT AS I WRITE THIS IT IS
STILL IN APPEAL. I WAS WONDERING IF YOU COULD SHED SOME LIGHT IN LAYMENS
TERMSABOUT POSSIBLE HEALTH EFFECTS THIS COULD HAVE UPON MY WIFE ,KIDS
AND I.ALSO AS I WRITE THIS THEY AREADDING A SECOND SET OF ANTENNA AND
ALL NESCESARY HARDWARE TO PROVIDE FOR A SECOND CARRIER. DOES THIS DOUBLE
MY FAMILIES EXPOSURE AND RISK. ANY INFORMATION YOU COULD PROVIDE WOULD
BE GREATLY APPRECIATED.
SINCERLY
