Aluminum Foil Shield Diminishes the Electromagnetic Radiation of Mobile Phones in the Cerebellum of Adult Male Rats

Aluminum foil (AF), which is a good conductor and non-magnetic, is proposed to reflect almost all of the electromagnetic wave's exposure. The effect of aluminium foil to the malondialdehyde (MDA) levels of adult male rat's cerebellum exposed to the electromagnetic radiation (EMR) from the mobile phones was analyzed. Thirty-two adult male rats were placed equally into four groups (n=8). Group I is the control group without AF or EMR without AF or EMR; group II is given the AF only; group III is treated to the EMR; group IV is treated to the EMR with AF shield. A mobile phone was taped at the timer floor of a plastic box container where the animal was placed. The AF shield has thickness of 2mm and the size of 20 x 160cm (Klin Pak, Indonesia) and covered the mobile phones wholly inside the plastic bag (in group IV). The mobile phone used has a specificity absorption rate europe (SAR EU) of 0,84-1,86 W/kg with a frequency band of 2100MHz (GSM 2100 MHz). The Exposure to the mobile phone's EMR was four hours daily for 30 days. The MDA levels were measured with the spectrophotometer (TBARS method) and analyzed statistically using KruskalWallis Test and Mann Whitney U (p<0.05). The MDA levels in P2 were significantly lower compared to those of P1 (p<0.05). Meanwhile, the MDA levels in P1 were significantly higher compared to the control group (p<0.05). In conclusion, aluminum foil could provide protective effect against the exposure of EMR oxidative stress in rat cerebellum.
