Am I getting zapped with microwave radiation?

Possibly.  Old microwaves may have leaky or damaged RF seals, or the door is no longer trued to the chassis.\n\nBut, the oven could also be dumping a lot of AC noise into the power lines.

They emit RF, the higher the frequency the more harmful the RF generally speaking. cell phones are in the 900mhz-1.8ghz range which given more power would be very harmful to the soft tissues of the human body. Cell phones do not put out enough power to be harmful as required by law in the FCC type acceptance for your specific phone. The FCC has set exposure limits on all emission devices which is also why some devices or radios are limited to occupational use only, as their emissions over time could be harmful. A PCS cell phone that put out 1000watts would be the same as sticking your head in a microwave which is why they generally only put out a quarter watt. Pbmao is incorrect in his summary of only infrared freq range is dangerous. Any frequency range given enough power can be dangerous. I have had a hole burned through my hand with a 900mhz radio putting out 500 watts. Stand between two subwoofers at 10hz and 10,000 watts and see what happens to your ear drums. Everything around you even the light that you see resonates or is a resonating frequency the spectrum starts off at sounds you can not even hear, to the electricity in your walls, to the light your eyes detects to see the world around you.

Hmm, I'm sitting here thinking about how microwaves work (yes, I do know how). If the pills have moisture in them (which I'm sure they do), then the electons in the pills can get energized by the microwaves and change the substance of the pills completely. The heat from the outside of the microwave itself though can alter the chemicals in the pills. It might be unlikely that anything happened to yours, but I'd just be on the safe side about it.

No, there's no evidence that microwaving food alters its composition or has any detrimental effects on living beings when microwaved items are eaten.\n\nMICROWAVES used in microwave ovens oscillate at 2450 million cycles per second (MHz). On the frequency spectrum , that region is located at the lower end of the radar band, slightly above the frequencies used for UHF (ultra-high frequencies) TV channels, and safely within the NON-ionizing region. However, it is important to note: Although microwaves do not carry enough energy to be ionizing, they can be dangerous. \n\n If microwaves can cook a piece of beef, these waves will also have the same effect on human tissue if it is exposed to high enough intensities for a long enough period of time. Certain body organs are particularly sensitive to this thermal effect. "Thermal" means heat. Thus, it is the heat produced by a hot stove that causes the careless cook to utter a sudden unsavory expletive. Likewise, it is the heat generated by the microwaves that creates the hazard in this case. \n\nInasmuch as the significance for humans of repeated exposure to low levels of microwave radiation is still unclear, there is enough evidence to warrant certain commonsense precautions: \n\nStay at least an arm's length away from an operating microwave oven \nDo not operate an oven when it is empty \nDo not operate an oven if the door will not close properly or is in any way damaged \nNever tamper with the safety interlock switches or the fuse \n\nhttp://en.wikipedia.org/wiki/Microwave\nhttp://www.gallawa.com/microtech/mwdanger.html\nhttp://www.encyclopedia.com/html/m/microven.asp

Microwave is any electromagnetic wave with "frequencies between 300 MHz (3 x 108 Hz) and 300 GHz (3 x 1011 Hz)."(1)\n\nThe most common impact could be seen in Microwave Ovens where food is heated up by causing the molecules in it to vibrate so fast, it heats up.\n\nIt is also used in radio broadcasting, radars & Wireless LAN protocols (e.g. Bluetooth). GSM mobile networks & cable TV use microwave.\n\nMicrowaves are used in maser, a device similar to laser, just that it operates at microwave frequencies.\n\nMore at: http://en.wikipedia.org/wiki/Microwaves

In a word, NO.  Now, in a much longer paragraph... :-)  After many years of study, there's not any conclusive evidence that exposure to WiFi (RF frequencies) has any effect whatsoever on living things and there are generally no health concerns, even if you placed your access point under your pillow.  RF exposure involves frequency, power and the duration of the exposure.  The human body most efficiently absorbs radio frequencies in the 30 to 300MHz range, and WiFi is at 2.4GHz.  So not only is the frequency much different, but WiFi products have strict power and RF emmissions requirements, such as 100 milliwatts maximum output power.  Plus, the WiFi RF energy is not "ionizing radiation" like it is UV light and Xrays, so WiFi frequencies pose no danger to human DNA the way prolonged sunlight UV rays cause skin cancers... What is actually of more concern is the RF energy from nearby FM radio stations!  (But they've been around much longer than WiFi, studied extensively, and again, nothing conclusive about any health concerns.)

Microwaves are part of the electromagnetic spectrum. As such any hot body will emit them. The peak frequency of the emissions of a body go up as it gets hotter. For your body the peak is in the infrared. For hot coals, it is in the red. Microwaves correspond to a temperature of a few Kelvin - about -260 C. Of course, at this temperature not much of any kind of radiation is given off, but what there is will peak in the microwave.\n\nFor commercial production of large amounts of microwaves- for ovens or radar - a magnetron is used.

It passes right through.   \n\nThe friction of the waves passing through is why food gets hot in the microwave.  Cell Phones and Wi-Fi do not have much power behind them is why don't cook but if you stand right in front of a microwave communication tower emitter you will be one roasted dude.  The guy that invented the microwave oven had discovered the application while working on radar arrays for the military and a candy bar in his shirt pocket had suddenly melted while he was standing near the emitter.\n\nThe dad of a friend of mine got mad one day and decided to throw a microwave into the street.  It smashed the door but still worked when we plugged it back in.  Even with the door open !  It felt pin-prickly and unpleasant if you put your hand in while it was running--  Don't try this at home !!

Depends on what sort of electromagnetic waves you mean...\n\nMicrowaves, X-rays etc\n\nStudies are being conducted all the time to test this, but most electromagnetic radiation found in the home has to have been judged safe by govermental bodies, otherwise it wouldn't be sold!!\n\nJust be wary of getting too close to microwaves if you have a heart pacemaker.

A microwave is a device that creates HIGH POWER microwave RADIATION. If this stuff gets to you, then there is a possibility of cancer.  Remember the deal with cellphones and cancer?\n\n    Inside the microwave you'll notice there is a steal mesh.  You see it in front of your microwave(It's got millions of holes in it).  This mesh is called a Faraday cage. What this mesh does is that it is actually protects you, by "blocking" the microwaves from escaping.  Remove the mesh and the microwaves have a chance to escape into the environment.\n\n    Cellphones also create microwaves.  But the microwaves coming from your cellphone, pale in power compared to the microwaves coming from the oven.  \n\n    Remember that radiation get's embedded into your skin.  It stays there for a long time, and eats away at you slowly.

First thing it is signal. But to see how good signal you are getting. You can double click your tinny monitor from your taskbasr showing wireless connection (connected). Once you open that window you will see a bar showing the percentage of signal you are getting. It is just like a bar in Cellular phone.\n\nHope it will help.

They are generaly about 800 mghz. RF \nThink they can go as low as 600 and way up to 2400 mghz.\n\nMicro waves are used in telecomunications but not " in " \nyour cell phone.\nThis picure of a microwave tower has just about every shape \nmicrowave dishes come in. (thows curved things that bounce the microwave signal) any ways they are line of sight \nthat means the dish has to be aimed directly at another dish.  If cell phones used microwave technology you would \ntotaly have to like climb a tower and aim your phone in just the right diection to get a signal.\nany ways heres a pic of a microwave tower\nhttp://www.drgibson.com/towers/bountifulmain.jpg\nit carys lots of conversation over a distance so we \ndon't have to string up more telephone polls everywhere.\nand here is a tower for a cell site\nhttp://wallybloss.com/images/22Cell_SIte_Cook_Rd_3.JPG\nAnd here's a few pics of the actual building were I \nused to work on telephone switches.\nhttp://www.thecentraloffice.com/Calif/IE/AT&T%20San%20Bernardino/AT&TSanbern.htm \nlove that place that was allot of fun, getting to know\n what makes a phone call work and how to build that stuff.

Intensive testing has been undertaken, and long term tests are still being performed. Current thinking is that modern mobile handsets cannot harm the human body, although in the interests of caution, you are advised not to let young children or babies use such devices (as the bones are still soft, they could be more susceptible).\n\nTests on mice and rats have shown tumour growth when subjected to prolonged exposure to the type of radiation produced by mobile phones, but only when the level is much higher than modern mobile phones (about 5x more!) and the duration much longer than would normally be present.\n\nAlso, modern digital mobile phones only produce harmful radiation when in use (i.e. when surfing or calling) or when reporting position to the network (about once every 15-45 minutes depending on network setup). \n\nThe new generation of mobile phones (3G) use a different type of digital transmission and power control is much more important than was the case for the older phones, so the level of radiation should be much reduced again.\n\nThere has been no reports of heart attack or cardiac disturbance from mobile phone use, the only dangers are over-heating / exploding when being charged or used excessively but needless to say these effects are extremely rare.\n\nSo, I would say there is no danger in keeping a mobile phone in a shirt pocket - in fact, I do!

well, how about a microwave's affect on a potato, compared to visible light, or radio length waves.\n\nwith enough energy, you could get some heat-up (absorption) at most any frequency but not the inside out efficient heating that you get with microwaves.

Yes we can generate beams of microwaves.  In fact, the air force is currently in the test phase of such a thing as a potential non lethal force weapon to dispurse crowds. \n  Supposedly, this beam is to cause discomfort in people by heating the liquids in their skin and causing "burns".  I really don't think it will be put into use as microwaves aren't really the safest things to be shooting at people. \n  As far as the electormagnetic field goes yes a microwave beam would accually be in the electromagnetic spectrum.  Try looking up somthing called a MASER.  You may find some good info on the web about it.

The 1800 has double the energy emission but both are pretty much negligable to the human anatomy\n\nAnd no, being near microwave-oven frequencies doesn't matter. Many many wireless consumer items use the 2.4ghz frequency and no ones brain is being fried.... unless you're infront of the tv 12 hours a day... but that's a differnet story
