Aluminium foil dampened the adverse effect of 2100 MHz mobile phone–induced radiation on the blood parameters and myocardium in rats

Abstract

Mobile phones emit a radiofrequency radiation (RFR) that might have adverse health effects. We aimed to investigate the possible protective effects of aluminium foil (AF) as a physical shield against the RFR from mobile phones on the blood parameters and the myocardium in rats. The effects of whole body 2100 MHz with 0.84-1.86 W/kg of SAR, 4 h/day for 30 days Global System for Mobile Communications (GSM)-RFR exposure for 4 h/day for 30 days on blood parameters (i.e. haemoglobin, leucocytes, thrombocytes, erythrocyte sedimentation rate, white blood cell differential count, corticosterone, CKMB), and the histology of myocardium were investigated. Three-month-old male rats (n = 32) were studied and randomised equally in the following four groups: K1 (non-AF non-RFR control), K2 (AF non-RFR control), P1 (non-AF RFR-exposed), P2 (AF RFR-exposed). Data were analysed with level of significance of p < 0.05. In P1, lower leucocytes and neutrophils counts with high corticosterone levels were found compared with the control groups, whilst a significantly higher CKMB was observed compared with P2 (p = 0.034). Lower cardiomyocyte counts congruent to the area fraction of the non-fibrotic myocardium were observed in P1 compared with the other groups (p < 0.01). AF might decrease the inflammatory-oxidative stress on rodent's blood cells and myocardium induced by the exposures of radiofrequency radiation of the mobile phones.

Association Between Mobile Phone Radiation Exposure and the Secretion of Melatonin and Cortisol, Two Markers of the Circadian System: A Review

“…All of these studies were carried out with healthy participants and used mobile phones or base station‐like exposures with levels less than the ICNIRP's RF exposure limit; however, only one study has reported an effect while others did not. It is important to emphasize that the observed effect could be due to chance as a result of a small number of participants [Jarupat et al, 2003] ( n = 8). Also, the use of urinary excretion data or blood and salivary single samples for melatonin that is secreted in a circadian manner can complicate interpretation; i.e.…”
