Abstract

Electromagnetic Fields of Mobile Phone Jammer Exposure on Blood Factors in Rats Shojaeifard MB, Jarideh S, Owjfard M, Nematollahii S, Talaei-Khozani T, Malekzadeh M. Electromagnetic fields of mobile phone jammer exposure on blood factors in rats. J Biomed Phys Eng. 2018 Dec 1;8(4):403-408. Abstract BACKGROUND: The increasing demand for using mobile phones has led to increasing mobile phone jammers as well. On the other hand, reports show that exposure to electromagnetic field causes an increase in the incidence of diseases such as leukemia, cancer, depression and failure in pregnancy outcomes; therefore, the aim of this study is to investigate the effects of exposure to electromagnetic fields of mobile phone jammers on blood factors. MATERIALS AND METHODS: Thirty male Wistar immature and thirty mature rats were selected randomly and each one was divided into three groups of ten. The control group did not receive any radiation; the sham group was exposed to a switched-off jammer device and the experimental group was exposed to electromagnetic fields (EMF) radiated by Mobile Phone Jammer daily eight hours for five days a week during forty days. Blood sample was taken from heart and blood factors including PLT, MCHC and RDWCV were measured. The data were analyzed by ANOVA which was followed by Duncan's test. RESULTS: The data from mature rats revealed that jammer usage led to a significant difference in blood factors including RBC, platelet, hemoglobin, hematocrit, MCV and RDWCV (P≤0.05); however, the number of lymphocytes, WBC and MCVH in the blood was the same in all groups. In immature rats, the exposure to jammer did not change RBC, lymphocyte and WBC count, hemoglobin and hematocrit; while, the platelet count along with MCHC, MVC and RDWCV changed by jammer radiation. CONCLUSION: The results exhibited that mobile phone jammer caused frequent changes in blood cell factors. Open access paper: ncbi.nlm.nih.gov

Main findings

In mature rats, exposure to EMF from a mobile phone jammer was associated with significant differences in several blood factors (RBC, platelet, hemoglobin, hematocrit, MCV, RDWCV; P≤0.05), while lymphocytes, WBC, and MCVH did not differ across groups. In immature rats, RBC, lymphocytes, WBC, hemoglobin, and hematocrit did not change, but platelet count, MCHC, MCV, and RDWCV changed with jammer radiation.
