Studies on Cell Antenna

Professor Magda Havas has created a report for us that is specific to our situation. The towers over the firehall have never had commercial towers placed on it because the International Association of Fire-fighters had not allowed it.  This change is most unusual and goes against firewall policy.

Since the IARC designated cell phone Base Stations (BS) as a possible cause of cancer, recent studies have started to appear concerning the negative effects from living in close proximity to the towers.  Just like damaging cell phone research was suppressed and took a long time to reach the public, the same is now happening with cell phone towers. Finally, governments are acting to warn their citizens. Here are a few of the most notable well researched studies that have become available.

Mortality by neoplasia and cellular telephone base stations in the Belo Horizonte municipality, Minas Gerais state, Brazil

Published Sept 2011.

This well funded study was done by the Municipal Government of Belo Horizonte, Municipal Health Department, Belo Horizonte City, Minas Gerais State, Brazil. It showed that in persons that live within 500 meters of a cell antenna base station (BS) there was a much higher death rate from neoplasia which is the abnormal proliferation of benign or malignant cells which cause tumours.

Abstract

Pollution caused by the electromagnetic fields (EMFs) of radio frequencies (RF) generated by the telecommunication system is one of the greatest environmental problems of the twentieth century. The purpose of this research was to verify the existence of a spatial correlation between base station (BS) clusters and cases of deaths by neoplasia in the Belo Horizonte municipality, Minas Gerais state, Brazil, from 1996 to 2006 and to measure the human exposure levels to EMF where there is a major concentration of cellular telephone transmitter antennas. A descriptive spatial analysis of the BSs and the cases of death by neoplasia identified in the municipality was performed through an ecological–epidemiological approach, using georeferenced. The database employed in the survey was composed of three data banks: 1. death by neoplasia documented by the Health Municipal Department; 2. BSs documented in ANATEL (“Agência Nacional de Telecomunicações”: ‘Telecommunications National Agency’); and 3. census and demographic city population data obtained from official archives provided by IBGE (“Instituto Brasileiro de Geografia e Estatística”: ‘Brazilian Institute of Geography and Statistics’). The results show that approximately 856 BSs were installed through December 2006. Most (39.60%) of the BSs were located in the “Centro-Sul” (‘Central-Southern’) region of the municipality. Between 1996 and 2006, 7191 deaths by neoplasia occurred and within an area of 500 m from the BS, the mortality rate was 34.76 per 10,000 inhabitants. Outside of this area, a decrease in the number of deaths by neoplasia occurred. The greatest accumulated incidence was 5.83 per 1000 in the Central-Southern region and the lowest incidence was 2.05 per 1000 in the Barreiro region. During the environmental monitoring, the largest accumulated electric field measured was 12.4 V/m and the smallest was 0.4 V/m. The largest density power was 40.78 μW/cm2, and the smallest was 0.04 μW/cm2.

 

Conclusions

This research showed the existence of a spatial correlation between cases of death by neoplasia and the locations of the BSs, in the Belo Horizonte municipality from 1996 to 2006. The mortality rates and the relative risk were higher for the residents inside a radius of 500 m from the BS, compared to the average mortality rate of the entire city, and a decreased dose–response gradient was observed for residents who lived farther away from the BS. The major antenna concentration was located in the Central-Southern SD of the city, which also had the largest accumulated incidence.

Vini Khurana (Australia,neurosurgeon) and Lennart Hardell (Sweden, oncologist) have published a summary of ten studies that reported health effects of populations living near cell towers. They found risks for cancer and neurological disease in eight out of ten studies – within 500 meters of the cell antennas. It is important to remember that not all cell tower antennas are the same, and the RF exposures around them can vary widely. Major macrocell sites can emit 6000 watts or more, and smaller sites can be less than 2000 watts. The distance outward from a cell tower that creates the ‘zone of RF impact’ needs to be assessed on a site-specific basis.

Abstract
Human populations are increasingly exposed to microwave/radiofrequency (RF) emissions from wireless communication technology, including mobile phones and their base stations. By searching PubMed, we identified a total of 10 epidemiological studies that assessed for putative health effects of mobile phone base stations. Seven of these studies explored the association between base station proximity and neurobehavioral effects and three investigated cancer. We found that eight of the 10 studies reported increased prevalence of adverse neurobehavioral symptoms or cancer in populations living at distances < 500 meters from base stations. None of the studies reported exposure above accepted international guidelines, suggesting that current guidelines may be inadequate in protecting the health of human populations. We believe that comprehensive epidemiological studies of longterm mobile phone base station exposure are urgently required to more definitively understand its health impact.

Specific Health Symptoms and Cell Phone Radiation in Selbitz (Bavaria, Germany)—Evidence of a Dose-Response Relationship

In January 2009, 251 Bavarian residents were tested to before and after a cell tower was erected in their town.  This study shows the changes that are experienced by the citizens.

 

How does long term exposure to base stations and mobile phones affect human hormone profiles?

This present study revealed that high RFR emitted from either mobile phone or base station has tangible effects on pituitary–adrenal axis represented in the reduction of ACTH and consequently cortisol levels. Also, exposure to RFR is associated with decrease in the release of thyroid hormones.

 

The Influence of Being Physically Near to a Cell Phone Transmission Mast on the Incidence of Cancer

Summary

Following the call by Wolfram König, President of the Bundesamt für Strahlenschutz (Federal Agency for radiation protection), to all doctors of medicine to collaborate actively in the assessment of the risk posed by cellular radiation, the aim of our study was to examine whether people living close to cellular transmitter antennas were exposed to a heightened risk of taking ill with malignant tumors.

The basis of the data used for the survey were PC files of the case histories of patients between the years 1994 and 2004. While adhering to data protection, the personal data of almost 1,000 patients were evaluated for this study, which was completed without any external financial support. It is intended to continue the project in the form of a register.

The result of the study shows that the proportion of newly developing cancer cases was significantly higher among those patients who had lived during the past ten years at a distance of up to 400 metres from the cellular transmitter site, which has been in operation since 1993, compared to those patients living further away, and that the patients fell ill on average 8 years earlier.

In the years 1999-2004, ie after five years’ operation of the transmitting installation, the relative risk of getting cancer had trebled for the residents of the area in the proximity of the installation compared to the inhabitants of Naila outside the area.
