Formal Report RadioTelevision Health Risks Essay
Formal Report RadioTelevision Health Risks - Essay Example Consequently, this rate of technological evolutions has evolved with unquantified health hazards being addressed. In this paper we try to excavate the negligible yet lethal health anomalies that are caused by the use of the contemporary technology like the Radio, Mobile phone and Television. Stern, Alan H. (1999): Radio frequency (RF) is electromagnetic energy that makes up the electromagnetic spectrum. This includes energies like gamma rays, X-rays, and light. This energy comprises of waves of electric and magnetic energy that moves together (radiating) through space. The RF waves are developed due to the movement of electrical charges in the aerials and radiate away from the antenna. This electromagnetic waves travel at the speed of light. With the ionization effect inherent in the electromagnetic waves, electrons are therefore stripped from atoms and molecules which create molecular changes that lead to damage in the genetic tissues like the DNA cells. IEEE (2006) The energy levels related with radio frequency energy includes both radio waves and microwaves are so weak to cause the ionization of atoms and molecules, hence it's a non-ionizing radiation in the same category with the infrared radiation (heat). Large amounts of RF energy can heat up tissues and create a temperature rise. Radiation for example, that are emitted by the TV and the computer monitors have adverse effect on the eyes and testes because of the little blood in them to carry heat away. IEEE (2006) Radio Frequency (RF) fields us the supreme at its source, and diminishes quickly with distance. However, due to their lower frequency, at comparable RF exposure levels, the body absorbs up to five more of the signal from FM radio and television than from stations. The reason behind this is because, frequency used in FM radio (around 100MHz) and in TV broadcasting (relatively 300 to 400 MHZ) are lower than those employed in mobile telephony (900 MHz and 1800MHz) and because a person's height makes the body an efficient stations have been in operation for the past 50 or more years without any adverse health consequence being established. Radio technologies employ analog signals, while modern wireless telecommunications use digital transmissions. With wide spread base stations all over, the probability that people are cancer infected is very high, and prevalently near the this base stations. Based on studies that are carried out in the last century, a keen relationship between RF transm itters and cancer have been published. On the one hand, this evidence has not given evidence that RF exposure from the transmitters increases the risk of cancer. On the other hand, long term animal studies have not established
