Subject: RE Double exposure (Leifheit)(Cherry). Date: Mon, 20 Nov 2000 015044 -0600 From: Roy BeaversTo: guru -------------------------------------------------- .........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???) -------- Original Message -------- Subject: RE: Double exposure (Leifheit). Date: Mon, 20 Nov 2000 20:22:19 +1300 From: Neil Cherry Reply-To: "neil.cherry@crc.govt.nz" Organization: Canterbury Regional Council To: "'roy@emfguru.com'" 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 ?

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.... -------- Original Message -------- Subject: cell tower emf Date: Sat, 18 Nov 2000 16:52:33 -0500 From: "Bruce Leifheit" To: 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.
