The pole was about half a mile (maybe more) from the antenna for a million watt ELF transmitter used for communications to submarines. I don't think I would worry about the leakage from a 700 watt microwave then. You are already "well done" inside ;-) |

They were really afraid of microwaves in the late 60s and the regs were pretty tight. I think you would lose the bet. The allowable leakage spec for a microwave oven in 1969 was 10mw/cm2 Today, the leakage spec is half that ... 5mv/cm2 In 1969, 155 microwave ovens were surveyed in New York, Mississippi, New Jersey and Massachusetts and tested for leakage. 32 percent of the 155 ovens had leakage in excess of the 10mv/cm2 standard. It's 46 years old. I doubt it would pass the leakage test, even to the 1969-1970 standards. I am going to try Wayne's WiFi test later this evening. I will stream a movie on my laptop so I will be hitting it hard enough to notice. There is a very exotic test described on the following link (Method 2) but Wayne's test is probably just as good. Just make sure your laptop is sitting in front of the microwave. I've always been concerned with all the electromagnetic energy we are exposed to everyday from things like microwaves and especially cell phones that you hold up to your head when using. You are within the "near field" (max energy strength) on a cell phone and I just don't believe that long term exposure is harmless. Texting is probably much safer. http://www.wikihow.com/Check-a-Microwave-for-Leaks Growing up I remember hearing the local radio station on our telephone. Ma Bell finally cleaned it up after a while, but then in high school I worked with the Chief Engineer at that station in his backyard electronics shop. He told me that in the field out behind the antenna he'd measured nearly a volt of signal strength in the air. It was only 5000 watts AM, 3000 FM. I worked there as a DJ my senior year of high school. Yes, it was fun. ![]() One of my duty stations was a transmitter site in Puerto Rico.

When I was at Keesler AFB for tech school, they ran the search radar on low power and pointed skyward. We were at least 3/4 mile from the antenna. Big investigation as to how the antenna got rearmed lower after a couple people in the barracks complained available up the fluorescent desk lamp blinking. |

I went to 3-5th grades at Ramey Air Force Base with the B-36s rumbling all the time. I think it was from 1973 to 1975. Transmitter site was in Ponce, on the south side of the island. That was about 20 years after we were there. Ponce rings a bell, so we must have gone there for something. We lived for the first year or so in Isabella, on the northwestern end of the island. Then we got quarters on base. |

I heard you say my microwave was spying on me but I can't find the camera or the microphone. Where are they? I want to disable them. http://gfretwell.com/ftp/microwave.jpg Try looking in Poco, Bill, or Justin's ass. I'm sure it's familiar territory! |
