EM radiation can range from very low energy to very high energy, and we call this span the electromagnetic spectrum. Within the EM spectrum, there are two types of radiation -- ionizing and non-ionizing. Feeling a bit overwhelmed? Don't worry, we'll explain all this in detail on the ...
How much radiation do these machines produce? How does it compare to medical imaging devices? And is it enough to increase cancer rates in the general population? Then there are the questions about privacy. Can TSA agents see bits and pieces they shouldn't be seeing? And do they ever ...

as well as seven other scanners not in active use at the time of measurement, found that full-body scannersdeliver aradiationdose equivalent to what a standard man receives every 1.8 minutes on the ground, or every 12 seconds during an airplane flight. ...
Every time we board a flight, we hear someone ask (almost wishfully), "Can you use your phone on a plane?" No, you can't, making a flight one of the few places where federal regulations bar you from using your device — or rather, your device's capability to connect to a phone ...
In short order, laboratory space on campus was cleared and the misleadingly named “Radiation Lab” was established. Its brief was to design, build, test, and get into production what became known as microwave radar, made possible by the revolutionary resonant cavity magnetron. Within three month...
Keep away from potential radiation sources like HD cameras that might lack proper EMI shielding Here are a few mounting ideas: On top of your GoPro/HD camera. On top of the frame if using an under-slung battery setup. On a mast to elevate the GPS away from the quad. However, be caut...
When a plane flies at steady speed, the forward thrust made by the engines is equal to the air resistance (drag) pulling back. The upward force of lift created by the wings is equal to the downward force of the plane's weight. In other words, the two pairs of forces are in perfect...
When it burns, DU forms a uranium-oxide smoke that is easily inhaled and that settles on the ground miles from the point of use. Once inhaled or ingested, depleted-uranium smoke can do a great deal of damage to the human body because of its radioactivity. See How Nuclear Radiation Works...
The (hypothetical) lay of the land at a commercial airport. See more pictures of flight. © HowStuffWorks "The Memory Trap," an espionage thriller by British author Anthony Price, contains this wry quote about airports: "The Devil himself had probably re-designed Hell in the light of th...
