I don't doubt that high levels of RF can be dangerous. The first two chief
engineers I worked with both died of cancer in their 50s. Wouldn't FM broadcast antennas be an even greater concern? The height of most adults would make them resonant somewhere near, or in, the FM broadcast band. Comparing wavelengths of "people" based on their height is ridiculous. Microwaves are a much shorter wavelength and cause much more damage to the human body, so the wavelength of people based on their height theory needs to be thrown out right away. I'd expect energy transfer to be more effiecnt from the FM broadcast antenna to the human body than it is in the AM broadcast band. This is like the argument that you should vote for the lesser of two evils, rather than vote for a good candidate. Why choose to live near an AM or FM broadcast antenna? I would not want to live next to either. What is more annoying is how cellular telephone antennas are getting to be impossible to avoid, and new ones are being put up every week. Anyway, there's been over 80 years of kW+ levels of AM broadcasting, and it seems strange this leukemia concern has gone unnoticed until now. 80 years is only one generation of people. Give it time. Old time radio commercials have doctors endorsing cigarettes that are healthy and good for you and your throat. Cell phones have not been in use long enough for the evidence to exist to convince those that don't have the radio background to know how dangerous they are now, without needing to see several generations of people suffer from them first. Aspartame is only now starting to get the attention that I was aware of decades ago. Now we have Sucralose (not sucrose) and Ace K, and again, we will have to wait around 20 years or longer before enough people have suffered to start to consider them a health threat. |

To oversimplify a bit: Low frequencies (like AM broadcast) pass through the body without being absorbed. Microwave frequencies bounce off the body without being absorbed. It's the frequency range between 30 and 300 MHz where maximum absorption takes place. Art H. |

Within these hallowed halls, Truth of added the
following to the collective conscience: To oversimplify a bit: Low frequencies (like AM broadcast) pass through the body without being absorbed. Microwave frequencies bounce off the body without being absorbed. ROTFFL!!! Why not PROVE your ridiculous theory by putting your head into a microwave oven! .......yeah. I didn't think so. I was actually wondering what this post of yours had to do with broadcasting. Even if it was off topic but informative or entertaining, it would have been better than just being a post about being rude to someone. |

Why not PROVE your ridiculous theory by putting your head into a microwave oven! I said this was a simplification. The point is that maximum absorption occurs in the 30 to 300 MHz range. Microwave frequencies are used for cooking because they are more practical to produce, not because they are more effective at heating. See the ANSI (American National Standards Institute) exposure limits curve below: http://www-training.llnl.gov/wbt/hc/.../slide34lg.gif Greatest rf absorption (minimum allowable exposure) is in the 30 to 300 MHz range.
