Kalau malas baca tulisan lengkap dari link diatas, berikut kutipan ringkasannya:
Quote
  There have been many studies of the the biological effects of EM radiation, many of these have been inconclusive. Using the research available, the following observations can be made:
  • Electrical fields of intensity similar to that found in the proximity of overhead power lines, may cause psychological responses such as changes in complex reasoning and arousal of humans.
  • In very special conditions as explained earlier, in the presence of weak radiation, the human body's biological rhythm may be altered, and in animals it has been shown the intense exposure to radiation can slow down the production of the hormone Melatonin. Changes in the level of this hormone have been linked to causing cancer.
  • Acute radiation exposure in human subjects has been shown to cause headaches and alterations in visual responses evoked by the radiation.
  • In the presence of intense radiation, human reproduction may experience behavioural deficiencies as well as retardation in development.
Due to the effects that EM radiation can cause, it is useful to be able to measure and limit the amount of radiation emitted from cellular transceivers which may be used to transmit data or voice signals. This requires a model of the human head, which is achieved by using the Phantom model. Radiation absorption is measured using the SAR unit. In conclusion, the effects of EM radiation are only a threat if the dosage of radiation is very high. In the case of cellular transceivers, the dose is not very high. Most of the latest studies that have been done on the subject, have returned inconclusive results and so it is impossible to give a definite answer to the question of whether cellular communications are bad for your health.
 Further research is always being carried out, with phone companies eager to invest in research so as to ease their consumer's fears. Many companies are taking advantage of the public's fear by selling products such as shielding cases which enclose the cellular tranceiver and shield the user from the majority of EM radiation emitted by the phone. These tend to decrease the reception capability of the phone units.
