They found no ink between a mMher's exposure to the towers during pregnancy (based on the distance from the home to the nearest lower and on the amount of energy gwan off by nearby towers) and the risk of early childhood cancer. The amount of exposure from Irving near a cal phone tower is typically many times lower than the exposure from using a call phone. About 30 studies have looked at possioie inks between cal phone use and tumors in people. Most studies to date have not found a link between cal phone use and the development of tumors, although these studies have had some important bMations. This is an area of ache research. For more etormabon, sae the document, Cellular Phones. What expert agencies say The 3 expert agencies that usually classify cancer -causing exposures (carcloogens) — the International Agency for Research on Cancer (IARC), the National Toxicology Program (NTP), and the US Environmental Protection Agency (EPA) — have rat classified cal phone havers as to their cancer -causing potential. According to the Word Health Organization: Considering the very low exposure levels and research results collected to date, there is no convincing scientific evidence that the weak RF signals from base stations and wireless networks cause adverse health effects. In commenting on cal phone towers near tortes or schools. the Federal Communications Commission states: Radehequency emissions from antennas used for cellular and PCS (personal communicatbris service) transmissions result io exposure levels on the ground that are typically thousands of times below safety limits. These safety limits were adopted by the FCC lased on the recommendations of expert organizations and endorsed by agencies of the Federal Government responsible for health and safety. Therefore, [tare's no reason to believe that such towers could constitute a potential health hazard to nearby residents or students. 11 ,�i `11 ♦� 'iAr♦ � t�r f � er I}}-- rsB114 is usi ,.%414 1 "farms ., �`i � N �t� V-� �• \.i J.L illy 1', OS Park - a 1 IrO +OSCIILOKC Or PiOn� � I �' (: hestnri aria esiain ns t A ` 'MW/ b - it ,.

Whie high levels of RF waves can cause a warming of body tissues, the energy levels on the ground near a cell phone tower are Far below the levels needed to cause this effect. Thus far, there is no evidence in published scientific reports that cell phone towers cause any other health problems. Questions? 12 5/10/2017 ® wr anux� sroasoe n e�er.oxrs' .....�o..

Do copular phone towns eauo r cancer? Do cellular phone towers cause cancer? Some people have expressed concern that living, working, or going to School near a cell phone lower might Increase the risk of cancer or other health problems. At this time there is very little evidence to support this Idea. In theorythere are some important points that would argue against cellular phone towers being able to cause cancer. First, the energy level of radlolrequancy (RF) waves Is relatively low, especialy when compared with the types of radiation that are known to increase cancer risk, such as gamma rays, x-rays, and ullravolet (UV) light. The energy of RF waves given oft by cal phone towers is not enough to break chemical bonds In DNA molecules, which is now, these stronger forms of aviation may lead to cancer. A amend issue has to do wfth wavelength. RF waves have long wavelengths, which can only be concentrated to about an Inch or two In spe. This makes it unlikely that the energy from RF waves could be concentrated enough to affect Individual cells In the body. Third, even d RF waves were somehow able to affect cells in the body at higher Wass, the level of RF waves present at ground level Is very Ow -- well below the recommended limits. Levels of energy from RF waves near ices phone towers are not significantly different then the background levels of RF radiation In urban areas from other sources, such as radio and television broadcast stations. For these reasons, most scientists agree test cell phone antennas or toners are unlikely to cause cancer. 10 5/10/2017 FCC 60nsann Fsds LnmIX4YY1.1.N1E.

MW., In the case of cellular and PCS cell site transmitters, the FCC's RF exposure guidelines recommend a maximum permissible exposure level to the general public of approximately 580 microwatts per square centimeter. This limit is many times greater than RF levels typically found near the base of cellular or PCS cell site towers or in the vicinity of other, lower -powered cell site transmitters. Calculations corresponding to a "worst -case" situation (all transmitters operating simultaneously and continuously at the maximum licensed power) show that, in order to be exposed to RF levels near the FCC's guidelines, an individual would essentially have to remain in the main transmitting beam and within a few feet of the antenna for several minutes or longer. Thus, the possibility that a member of the general public could be exposed to RF levels in excess of the FCC guidelines is extremely remote. 5/10/2017 RF Questions -- .,,. . - - -- _ — -- ____-- " 'r°'. .� � �f ,_ ,..,..,.ate __ ...._ �y�;�. -' �� _._ �. _ ._ _,,,, �' .6a ✓�.y_„I�..
