Metal-framed spectacles and implants and specific absorption rate among adults and children using mobile phones at 900/1800/2100 MHz

Electromagn Biol Med. 2006;25(2):103-12. doi: 10.1080/15368370600719042.


The specific absorption rate (SAR) from mobile telephones at horizontal and vertical positions is investigated in human adult and child heads wearing metal-rim spectacles and having metallic implants. The SAR values calculated by Finite Difference Time Domain (FTDT) method are compared to the actual ANSI/IEEE standards and to the 900/1800/2100 MHz electromagnetic radiation limits according to EU standards. Our calculation shows a maximum of the cellular SAR in the child head, which in the case of metallic implant could be as much as 100% higher than in the adult head. The averaging on 1 and 10 g tissue-masses shows SAR generally under the limit of 519/1999/EC standards. However, in the case of 2100 MHz with vertical position of the phone for adults and of the 900 MHz for children with metallic implants the ANSI/IEEE limits are exceeded.
