6 Bhg. Tan Sri Dr. Mohamad Taha bin ArifDirector-General, Ministry of HealthFirst and foremost, I wish to extend my heartiestcongratulations to Professor Ng Kwan Hoong for hiscommendable efforts in producing this highly informativepublication entitled Radiation, mobile Phones, BaseStations and Your Health. This timely publication doesnot only provide general background information on thehealth effects from mobile phones and base stations butalso helps to alleviate anxiety of the general the technology rapidly advancing, mobile phoneusers and people living within close range of the mobilephone base stations have become increasingly concernedover the potential harmful effects of radiofrequencyradiation produced by these devices to their Ministry of Health has always been striving to play aneffective role as the guardian of public health.

7 In 1996,the Ministry appointed an interagency scientificcommittee to study and produce a report on the healtheffects of electromagnetic fields (EMF). This committeeconcluded that there is no conclusive evidence to indicatethat EMF exposures at levels normally encountered willcause harmful health effects. The above is also the findingsof the world scientific and medical community. Thiscommittee still monitors the current research worldwideand reports to the Ministry of Health , there continues to be a great deal ofmisunderstanding and misinformation on the issue ofsafety and radiation.

8 I am therefore very pleased that thisbook endeavours to promote a better understanding ofwhat is known and not known about radiofrequencyradiation, as well as to separate the myths from the again, I applaud Prof. Ng on his efforts and hiscontinuing contribution towards promoting betterunderstanding of radiation, in particular, its use in themedical SRI DR. MOHAMAD TAHA BIN ARIFixIntroductionThe telecommunications industry is experiencing a robustgrowth on a global scale. By the year 2005, the industrypredicts that there will be as many as billion mobilephone subscribers worldwide.

9 Since the introduction ofmobile phones in the mid-1980s, there has been asignificant increase in the number of mobile phone usersand installations of base stations. As of 2003, statistics fromthe Malaysian Communications and MultimediaCommission (MCMC), show that the mobile penetrationrate is 39 persons per 100 population or phones, sometimes known as cellular phones orhandsets, form an integral part of modern tele-communications and are fast becoming a social some parts of the world, they are the most reliable orthe only phones available. In others, mobile phones arevery popular because they allow people to maintainconstant and continuous communication withouthampering their freedom of does a mobile phone system work?

10 The individualmobile phone operates by communicating with a fixedinstallation known as a base station or a tele-communications structure. Since the mobile phone andits base station is a two-way radio, they produceradiofrequency (RF) radiation as a means ofcommunicating and expose the people near them to wide use of mobile phones has inevitably raised thequestion of whether there are any implications for humanhealth. There have been some reports relating to possibleadverse health effects and these have understandably ledto some concern from the members of the Radiation, mobile Phones, Base Stations and YourHealth, issues regarding human health effects from mobilephones and their base station antennas are addressed anddiscussed in the Frequently Ask Questions (FAQ)
