The Dangers of Radio Waves

!9# The Dangers of Radio Waves

[if ]
[endif]

Since the advent of cellphones in the 1990s, communication has become a lot easier and portable. In fact it has become impossible to imagine a world without them. Business transactions have increased exponentially in decision-making now takes place in a much quicker pace. In Africa, cellular technology has become the primary means of communication as telephone companies no longer have to spend billions of dollars building up telecommunication infrastructure.

Radio frequencies and magnetic fields have been controversial topics since the 1960s and 70s, and with the introduction of cellular phones, the controversy has exacerbated. As in every debate, there are two schools of thought surrounding the impact of radio waves and the danger they pose. On the one side, there are those who believe that radio frequencies have little effect on consumers and the environment at large. On the other side, there are those who believe that we are in serious danger from radio waves and the telecommunication companies that dupe us into believing that we are safe.

Radio frequencies or radio waves, as they are more commonly known, are emitted by wireless and other electronic devices. They are not a new occurrence in the modern world. In fact, apart from natural occurrences, radio waves have been around since radio and television. Basically anything that has an antenna or a transmitter emits radio waves. The rate at which the body absorbs radio waves is measured as the Specific Absorption Rate (SAR).

Controversy surrounding cell phone radiation is focused on whether radio frequencies emitted from cellphones are safe for humans and the environment, or whether we are all put at risk by the continuing omission of these waves as well as electromagnetic fields. When radio frequencies are high enough, they can break down the tissue in the human body and can interfere with the DNA. However, it is claimed that emissions from cellphones are so small that they pose no danger. This has been the mantra of the FCC for many years. There has been much confusion and concern recently as the same organization now claims that further research is needed to determine the effects of radio frequencies, as well as whether they are dangerous to humans.

Complaints have surfaced in the United States and other countries like South Africa where base stations are located in urban areas and even built in gardens where agreement is reached between cellphone networks and home owners. People living in close proximity to base stations have complained of headaches and other health problems. Home owner associations and health researchers have claimed that living too close to base stations or heavy use of cellphones may instigate brain tumors and cancers.

With no official conclusions drawn on the dangers of cellphones, and with more people complaining about the effects, one has to ask the following questions; how dangerous is radio frequencies and what are the risks to human health and the environment? Can constant exposure to radio waves cause free radicals to occur and if so, is there any way to protect ourselves? Are we slowly killing ourselves with the pollution of modern technology? Makes you think, doesn't it?

The acclaimed Wave music system still sets the standard for quality audio and ease of use among one-piece, table top stereos. No wonder so many people use it as their main home entertainment system. And you'll enjoy extra hours of uninterrupted CD music with the Wave music system multi-CD changer included in this package.

Simplicity by Design
The Wave music system was engineered for easy enjoyment right out of the box. No setup required: just plug it in and you're ready to go. The FM/AM radio and CD player are built in. There's an auxiliary input for your MP3 or other portable player, and a headphone jack for keeping the music to yourself.

The system's sleek appearance is uninterrupted by buttons, with all controls on a handy, slim remote. The large display panel is brightly lit and easy to read, prominently displaying the artist, title and album names of your MP3 CDs.

The Wave music system with multi-CD changer package lets you enjoy extra hours of uninterrupted CD music. Simply slide one CD or MP3 CD into the slot on the front of the Wave music system, and up to three more into the add-on multi-CD changer. One remote controls all CD functions, plus FM/AM digital tuner, clock and alarm. A spare remote is also included.

The changer has the same small footprint as the Bose Wave music system. Together they stand less than seven inches tall and can fit almost anywhere, unlike most conventional bookshelf stereos. The CD changer also provides an additional connection for another audio source, such as an iPod or DVD player.

Unique Bose innovations account for this compact system's hearty sound. Proprietary waveguide speaker technology delivers performance well beyond the speakers' size. Two 26-inch folded waveguides are precisely tuned to amplify the output from speakers to reproduce lifelike sound from a small enclosure. You'll hear full-bodied sound, especially in lower registers, for more natural-sounding bass and percussion instruments.
