Mobile Phone Antenna with Reduced Radiation into Inner Ear

Health hazards are of great concern to cellular phone users. One important measure of the effect of electromagnetic radiation into human body is the specific absorption rate (SAR). If the human body is exposed to electromagnetic radiation, the amount of power absorbed by its tissues per mass volume should be limited and not to exceed a maximum SAR value. The cellular phone radiated through its ...

The Study of Biological Effect of EM Radiation by Antenna at Different Position of Human Model

This paper presents an approach to modeling of field penetration and gives contribution to understanding the real effects of the fields and the sensitivity of human model to electromagnetic radiation generated by mobile antenna. When a human body is exposed to the electromagnetic radiation, because human body contain 70% of liquid, and it contain more liquid near of head, heart, abdomen (near o...

Radiation hazards for cardiologists.

Sir, The Editorial by Raphael and Tomlinson (1986;55:421-2) was an interesting review of some specific aspects of radiation dosage to cardiologists. The authors advised, quite correctly, that those performing catheterisations should be instructed in radiation safety practice before or early in their training. They did not point out, however, the complete absence of structured tuition in radiati...
