Health and high frequency electromagnetic fields / Rosmazita Hussain

In view of increasing proliferation of radio and microwave frequency fields to which people in the course of their every day life, questions have been raised regarding their safety. Obviously, these fields provide the society with invaluable services such as communication, navigation, defence and so many other applications. Physically, these fields are known to interact with the human body and under some circumstances it may affect the human health. Presently, the concern comes from two main factors: the presence of field sources very close to the human head and eye in particular and the uncertainty regarding the low level fields amplitude modulated at ELF. This study provides an overview of this issue. It gives details of the engineering research that has resulted in setting the safety standards. It highlights the experimental investigations that lead to the development of protection guidelines. Moreover it presents result using a CAD package regarding the distribution of fields due to the presense of a monopole antenna near a model of human body. Also, included in the study is the measurement of power levels available in our environment at different frequencies.
