“…These changes may indicate the high vulnerability of brain (Cao et al, 2004;Martinez-Samano et al, 2012 andGhanbari et al, 2016) and liver (Liu et al, 2013 andKivrak et al, 2017) and their susceptibility to oxidative stress (Ragy, 2015). The results corroborate the findings of Samta et al (2017) that the exposure of rats to 900MHz EMR for 2hr daily for 3 months causes a considerable damage in the liver, and brain.…”

“…The hematological effects of chronic exposure to ELF-EMFs in animals and humans have been studied (Cakir et al, 2009; Nadimi et al, 2017). Liu et al (2013) reported that the exposure of employees to ELF-EMFs increases the number of white blood cells (WBCs) and lymphocytes but decreases the mean platelet volume and hematocrit.…”

The present study aimed to determine the effect of taking antioxidant vitamins including vitamins E and C in reducing oxidative stress levels and improving blood parameters. This double-blind randomized controlled trial study was conducted among the employees working in different parts of a power plant in Semnan, Iran, in 2017. A total of 91 employees were randomly allocated to four groups including vitamin E (400 units per day), vitamin C (1000 mg per day), vitamin E + C for 90 days, and control. The levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (Cat), and total antioxidant capacity (TAC) in plasma, and hematological parameters were measured in the participants before and after the intervention. A significant increase was seen in the mean level of SOD, Cat, and TAC in the vitamin-treated groups as well as a significant decrease in mean MOD in vitamin C and vitamin E groups after the intervention. In the intervention groups, the number of red blood cells, hematocrit, and the level of mean corpuscular hemoglobin (MCH) and MCH concentration significantly increased. After the intervention, the mean levels of MDA, SOD, and Cat in vitamin E group were significantly lower than the control group. The mean level of TAC decreased only in the vitamin C group compared to the control group. Taking vitamins E and C as nonenzymatic scavengers of free radicals appears to decrease lipid peroxidation and increase the level of antioxidant enzymes, which can be imbalanced by exposure to extremely low-frequency electromagnetic fields in power plant employees. Furthermore, some hematological parameters can be improved by consuming these vitamins.

“…Recently; several studies have been performed to verify direct effects exerted by ELF-EMFs on living cells functions. Although the results have been somewhat controversial, a variety of cell responses have been observed involving proliferation and differentiation [1][2][3], gene expression [4][5][6], modulation of the membrane receptors functionality [7,8] and free radicals' generation [9][10][11]. In 2002, the IARC classified ELF-EMFs as a "possible human carcinogen" and the decision IARC was supported by the WHO in 2007 [12].…”

There is critical need to do a lot of experimental studies to calculate of the relative biological effects of non-ionizing radiation and comparing its effect with ionizing radiation to re-determine the safe exposure dose to non-ionizing radiation. This research is concerned with studying the relative fraction of damage (RFD) of the extremely low frequency electromagnetic fields (4kV/m-50 Hz) to high energy photons (6 MeV) on some biophysical properties of rats bone. In this regard, 100 male albino rats are used and divided into sub groups of 10 rats each. One group of animals was used as control group (unexposed group) and did not receive any treatment. Similar to occupational workers, four groups of animals were exposed 8h/day for periods from 1 to 4 weeks and were immediately sacrificed at the end of the exposure period. Four groups of animals exposed 8h/day for periods from 1 to 4 weeks and remained 45 days post exposure periods, then sacrificed. The last group of animals was exposed to a high energy dose of6 MeV of dose (1rad). Femur bone samples of each animal from all groups were collected and prepared for further biophysical investigations. In addition, RFD of magnetic fields exposures are calculated for each group relative to dose of 6 MeV-1 rad photons. Results of exposure to the electric field showed significant deterioration effect on the biomechanical parameters of femurs as a consequential defect of bone strength and bone quality as compared to the unexposed ones. Also, the results obtained from the groups that udergone a post exposure period of 45-days did not show amendment in bone biophysical characteristics, which means that permanent effects and chronic damage of bone tissues may have resulted. On the other hand, the RFD ratios illustrated that the effect of exposure to ELF EMF has no lower effect than the exposure to ionizing radiation and should not be underestimated.
