Radio Wave Safety

The safety of radio waves is an issue that has garnered a fair amount of interest among the public. In particular, the health effects of radio waves from mobile devices have been researched for over 50 years. The Radio-Radiation Protection Guidelines and related legal regulations have been established based on careful considerations by the World Health Organization and Japan's Ministry of Internal Affairs and Communications. DOCOMO operates its base stations in compliance with these guidelines and legal regulations and checks to make sure radio waves emitted by mobile phones are below the limits indicated in the guidelines.
In addition, lectures by experts from inside and outside the company are held on a regular basis to keep employees abreast of legal developments related to radio waves and the latest domestic and overseas research.

DOCOMO is involved in research on the health effects of radio waves that is being funded by the World Health Organization and Japan's Ministry of Internal Affairs and Communications. Since 2002 we have conducted experiments in collaboration with KDDI CORPORATION and SOFTBANK MOBILE Corp. regarding impacts at the cellular and genetic levels. Following an interim report issued in 2005, in 2007 we announced that research had identified no impacts. This was one example of scientific evidence that dismisses the argument that RF radiation has an impact on cell structure and function and can cause cancer. It once again shows that radio waves from mobile phones and base stations are safe.
Radio wave safety is an important social responsibility of mobile communications providers. We will continue to keep up with research developments at home and abroad and actively engage in survey and research activities conducted by the Association of Radio Industries and Businesses, a public-interest corporation working to develop radio wave use.
