Abstract

Effect of Base Transceiver Station waves on some immunological and hematological factors in exposed persons Taheri M, Roshanaei G, Ghaffari J, Rahimnejad S, Khosroshahi BN, Aliabadi M, Eftekharian MM. The effect of Base Transceiver Station waves on some immunological and hematological factors in exposed persons. Hum Antibodies. 2017;25(1-2):31-37. doi: 10.3233/HAB-160303. Abstract BACKGROUND: Since the number of mobile subscribers has significantly increased in recent years, the installation and deployment of Base Transceiver Station (BTS) antennas sending and receiving signals has become common and inevitable in different regions. OBJECTIVE: In this study, we have tried to evaluate the effect of the waves on some immunological and hematological parameters in exposed individuals. In this study, the exposed and non-exposed individuals were used as the test and control groups, respectively. METHODS: The test group was healthy people who resided in the vicinity of the Base Transceiver Station (BTS) antenna and received the maximum of radiation. The control group was selected from the healthy individuals that were matched with the exposed group by age. They resided in a distance of Base Transceiver Station (BTS) antenna and received the minimum of radiation. After stating complete explanations and obtaining the consent, the venous blood samples were taken from them. Then, CBC and the level of cytokines including IL-4, IL-10 and interferon γ were performed on the samples and the results were analyzed by SPSS software. RESULTS: In the test group, the whole number of white blood cells, the level of hematocrit, percent of monocytes, eosinophils and basophils were significantly lower than the control group. The number of red blood cells, their average volume and the mean concentration of hemoglobin were notably higher than the controls. There was not observed a significant difference between the two groups in hemoglobin, its mean concentration, platelet count, percent of lymphocytes and neutrophils as well as serum levels of cytokines IL-4, IL-10 and interferon γ . CONCLUSIONS: It seems that radiation of mobile phone antennas influenced the blood and immune systems, but further study should be done to exactly determine the targets. ncbi.nlm.nih.gov Also see: bit.ly

Evidence strengthLowConfidence: 74% · Peer reviewed: yes

Main findings

Compared with controls, the exposed group had significantly lower total white blood cell count, hematocrit, and percentages of monocytes, eosinophils, and basophils, and higher red blood cell count, average red cell volume, and mean concentration of hemoglobin. No significant differences were observed for hemoglobin, platelet count, lymphocyte and neutrophil percentages, or serum IL-4, IL-10, and IFN-γ levels.
