Hazards of electromagnetic wave

Electromagnetic wave invisible and has no smell. However a statistic data says that over 10% of mobile phone user preferably use wire phone as they have experienced headache, fatigue, dizziness symptoms. It shows the elderly or children with weak resistance especially have experienced severely.

Regarding the hazards of electromagnetic wave, NIEHS (National Institute of Environmental Health Sciences) and IARC (International Agency for Research on Cancer) defined electromagnetic wave as Class 2 Carcinogen in 1998. According to several press releases dated Dec. 22, 2004, as a result of REFLEX Research Project participated with 7 EU countries, the exposure to electromagnetic wave (800MHz band) of the mobile phone cut DNA of the cell and this damaged DNA doesn't recover over time and it is handed over next generation.

SEPA has been tested by KTL (Korea Test Laboratory), the most authoritative organization.
