Research on mobile base stations and their impact on health Epidemiological studies: Abdel-Rassoul, G., El-Fateh, O. A., Salem, M. A., Michael, A., Farahat, F. & ElBatanouny, M. (2007). Neurobehavioral effects among inhabitants around mobile phone base stations, Neurotoxicology, 28(2), 434-40. "The prevalence of neuropsychiatric complaints as headache (23.5%), memory changes (28.2%), dizziness (18.8%), tremors (9.4%), depressive symptoms (21.7%), and sleep disturbance (23.5%) were significantly higher among exposed inhabitants than controls: (10%), (5%), (5%), (0%), (8.8%) and (10%), respectively (P < 0.05). Inhabitants living nearby mobile phone base stations are at risk for developing neuropsychiatric problems and some changes in the performance of neurobehavioral functions either by facilitation or inhibition. So, revision of standard guidelines for public exposure to RER from mobile phone base station antennas and using of NBTB for regular assessment and early detection of biological effects among inhabitants around the stations are recommended." http://www.sciencedirect.com/science? _ob=ArticleURL&_udi=B6W81-4KJ6KKX-1&_user=950207&_rdoc=1&_fmt=&_orig=search &_sort=d&view=c&_acct=C000049138&_version=1&_urlVersion=0&_userid=950207&md5=7 afc509b28d10f0977a0c9dcb1f8e3db Eger, H., Hagen, K., Lucas, B.

Published in Umwelt Medizin Gesellschaft 17,4 2004, as: "Einfluss der räumlichen Nähe von Mobilfunksendeanlagen auf die Krebsinzidenz". "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." http://www.umg-verlag.de/umwelt-medizin-gesellschaft/404_ege.html Wolf, R. & Wolf, D. (2004). Increased incidence of cancer near a cell-phone transmitter station. International Journal of Cancer Prevention. Vol. 1, No. 2, April 2004. "Both measured and predicted power density (for the frequencies of 850 MHz) in the whole exposed area were far below 0.53 µw/cm² thus the power density is far below the current guidelines which are based on the thermal effects of RF exposure. Exact measured power density in each house are described in table 1. The current Israeli standard uses 50 packets/sec with Time-Division-Multiple-Access (TDMA) quadrature modulation. The antenna produces 50 packets/sec, using a 3:1 multiplexed Time-Division-Multiple-Access (TDMA) modulation with a 33% duty cycle. ...Cancer incidence of women in area A was thus significantly higher (p<0.0001) compared with that of area B and the whole city. A comparison of the relative risk revealed that there were 4.15 times more cases in area A than in the entire population." http:// www.umg-verlag.de/umwelt-medizin-gesellschaft/210_ej_z.pdf Blettner, M., Schlehofer, B, Breckenkamp, J., Kowall, B., Schmiedel, S.

Occup Environ Med 66:118-123. "In the initial phase, reported on in this paper, 30,047 persons from a total of 51,444 who took part in the nationwide survey also answered questions on how mobile phone base stations affected their health. A list of 38 health complaints was used. A multiple linear regression model was used to identify predictors of health complaints including proximity of residence to mobile phone base stations and risk perception. RESULTS: Of the 30,047 participants (response rate 58.6%), 18.7% of participants were concerned about adverse health effects of mobile phone base stations, while an additional 10.3% attributed their personal adverse health effects to the exposure from them. Participants who were concerned about or attributed adverse health effects to mobile phone base stations and those living in the vicinity of a mobile phone base station (500 m) reported slightly more health complaints than others. CONCLUSIONS: A substantial proportion of the German population is concerned about adverse health effects caused by exposure from mobile phone base stations. The observed slightly higher prevalence of health complaints near base stations can not however be fully explained by attributions or concerns." http://www.ncbi.nlm.nih.gov/pubmed/19017702 Bortkiewicz A, et al. [Subjective symptoms reported by people living in the vicinity of cellular phone base stations: review]. [Article in Polish] Med Pr. 2004;55(4):345-51. "The performed studies showed the relationship between the incidence of individual symptoms, the level of exposure, and the distance between a residential area and a base station. This association was observed in both groups of persons, those who linked their complaints with the presence of the base station and those who did not notice such a relation." http://www.ncbi.nlm.nih.gov/pubmed/15620045.

"Die mittlere Strahlenbelastung der höchstbelasteten Gruppen in Selbitz (1,2 V/m) lag deutlich höher als die untersuchte Studienpopulation der QUEBEB-Studie (1) des Deutschen Mobilfunkforschungsprogramms (Mittelwert DMF 0,07 V/m). Für die Beschwerden Schlafstörung, Depressionen, cerebrale Symptome, Gelenkbeschwerden, Infekte, Hautveränderungen, Herz-Kreislauf Störungen sowie Störungen des optischen und akustischen Sensoriums und des Magen-Darm-Traktes besteht eine signifikante dosiswirkungsabhängige Korrelation zu objektiv bestimmten Expositionslagen, die mit dem Einfluss von Mikrowellen auf das Nervensystem des Menschen erklärt wird." "The mean radiation measurements of the groups exposed at most in Selbitz (1.2 V/m) was substantially higher than the mean radiation of the study population studied in the QUEBEB study (1) of the German mobile telephone research program (Deutsches Mobilfunkforschungsprogramm DMF, established mean value DMF 0.07 V/m). A significant correlation was found dependent on dose-effects for insomnia, depressions, cerebral symptoms, joint illnesses, infections, skin changes, heart and circulation disorders, and disorders of the optical and acoustic sensory systems and the gastro-intestinal tract with objectively determined locations of exposure, which can be related by the influence of microwaves on the human nervous system."

Workshop PTZE Electromagnetics technics in preventive health, Lodz, Poland 13-15 December 2006 (Biuletyn PTZE, nr 14, Warszawa 2006, pp 23-26) "The study subjects comprised 500 people from 5 regions of the city of Lodz, living in houses located at the distances of up to 50 m, 50-100m, 100-150m, 150-200m and over 200m from the base station. The distance from base station is the estimated value of exposure to EMF. There were 181 (36.2%) men aged 46.2 29.0 years and 319 (63.8%) women aged 50.117.0 years. ...A significant relationship was found to occur between the frequency of some symptoms and the distance from the base station. Everyday headaches were most frequent in respondents living at the distance 100-150 m from the base station in comparison with subjects living in farther distances. Differences were statistically significant (p=0,013). Symptoms of depression were most frequently reported by people living at the distance 50-100 m (23,3%) and over 200 m (21,3%). Differences were at the borderline of statistical significance (p=0.059). It seems important to note that only 1.8% of subjects reported their concern about possible harmful effects of the base stations." Hutter, H., Moshammer, H., Wallner, P. & Kundi, M. (2006). Subjective symptoms, sleeping problems, and cognitive performance in subjects living near mobile phone base stations, Occupational and environmental medicine, 63(5), 307-13. "Total HF-EMF and exposure related to mobile telecommunication were far below recommended levels (max. 4.1 mW/m²). Distance from antennae was 24-600 m in the rural area and 20-250 m in the urban area. Average power density was slightly higher in the rural area (0.05 mW/m²) than in the urban area (0.02 mW/m²). Despite the influence of confounding variables, including fear of adverse effects from exposure to HF-EMF from the base station, there was a significant relation of some symptoms to measured power density; this was highest for headaches. Perceptual speed increased, while accuracy decreased insignificantly with increasing exposure levels. There was no significant effect on sleep quality. CONCLUSION: Despite very low exposure to HF-EMF, effects on wellbeing and performance cannot be ruled out, as shown by recently obtained experimental results; however, mechanisms of action at these low levels are unknown." http://www.ncbi.nlm.nih.gov/pubmed/16621850 Navarro, E., Segure, J., Portelés, M., Gomez Perretta, C.

"A health survey was carried out in Murcia, Spain, in the vicinity of a Cellular Phone Base Station working in DCS-1800 MHz. This survey contained health items related to "microwave sickness" or "RF syndrome." The microwave power density was measured at the respondents' homes. Statistical analysis showed significant correlation between the declared severity of the symptoms and the measured power density. The separation of respondents into two different exposure groups also showed an increase of the declared severity in the group with the higher exposure." http://www.informaworld.com/smpp/content~content=a713628989~db=all Santini, R., Santini, P., Le Ruz, P., Danze, J. & Seigne, M.

Electromagnetic Biology and Medicine, 22: 41-49 "A survey study was conducted, using a questionnaire, on 530 people (270 men, 260 women) living or not in proximity to cellular phone base stations. Eighteen different symptoms (Non Specific Health Symptoms-NSHS), described as radiofrequency sickness, were studied by means of the chi-square test with Yates correction. The results that were obtained underline that certain complaints are experienced only in the immediate vicinity of base stations (up to 10 m for nausea, loss of appetite, visual disturbances), and others at greater distances from base stations (up to 100 m for irritability, depressive tendencies, lowering of libido, and up to 200 m for headaches, sleep disturbances, feeling of discomfort). In the 200 m to 300 m zone, only the complaint of fatigue is experienced significantly more often when compared with subjects residing at more than 300 m or not exposed (reference group). For seven of the studied symptoms and for the distance up to 300 m, the frequency of reported complaints is significantly higher (P < 0.05) for women in comparison with men. Significant differences are also observed in relation to the ages of subjects, and for the location of subjects in relation to the antennas and other electromagnetic factors." http://www.informaworld.com/smpp/content~content=a713628949~db=all See also: Santini R, et al.

Wissenschaftliches Forschungsprojekt der Salzburger Landeskliniken (SALK), IGGMB Forschungsinstitut für Grund- und Grenzfragen der Medizin und Biotechnologie. Kurzbericht. "Das körpereigene Abwehrsystem wird tatsächlich geschwächt. Biochemisch zeigte sich in den Speichelanalysen, dass höhere Exposition zu einer biologisch relevanten Immunsuppression führte. Es zeigte sich eine statistisch signifikante Veränderung im Cortisolspiegel; weiters fanden sich auffallende Veränderungen in den Verläufen des alpha-Amylase-Spiegels, einem weiteren verlässlichen Stress-Marker, und im Immunglobulin-A-Spiegel (Antikörper-Ausschüttung im Speichel). Auch die GDVAnalysen zeigten nicht bei allen, aber bei vielen ProbandInnen immer wieder stressende Einflüsse auf. ...Fazit: Der "alte" "Salzburger Vorsorgewert" von 1000 µW/m² (= 1 mW/m²) aus dem Jahr 1998 erscheint absolut gerechtfertigt; er liegt eher zu hoch als zu niedrig, denn Veränderungen sind schon bei der Hälfte also bereits bei etwa 500 µW/m² erkennbar. Auch die Absenkung im Jahr 2002 erscheint damit auch auf Basis der vorliegenden Ergebnisse nachvollziehbar." http://www.salzburg.gv.at/handystrahlung www.salzburg.gv.at/gsmstudie.pdf Comment: 3 different radiation power density levels 3000 µW/m². , 540 µW/m². and 10 µW/m² were inspected. Blood samples indicated stress markers starting from the 500 µW/m² radiation power density level. As a summary, they recommend 10 µW/m² level (Salzburg Land (State) recommendation value).
