Yes and No. Typical Metal detectors DO NOT give off radiation, but the next generation metal detectors DO. You won't be able to tell which one you are walking through, except for the general rule of thumb that the older looking machines will cause no harm while the other, newer looking machines might.
Not really.
While x-rays CAN be used to detect metal - or rather stuff that is hard for x-rays to penetrate - the most commonly used method for metal detecting is electro-magnetic.
A wire coil sends out an magnetic pulse whci sets off an echo in any metal object that's close enough. Then that echo can be detected and the machine tha tell the operator that there's metal nearby.
Probably not.
Airport metal detectors are quite sensitive to metals, this includes metal implants that may have been placed inside your body. Belt buckles, key chains, and steel-toed shoes may set off these sensitive metal detectors. Many commonly used orthopedic implants may also set off the metal detectors.
Microwaves do not 'give off' radiation as such. Microwaves are radiation.
yes it will because steel is a type of metal
I don't think you can because of the metal on them. Try a book of matches if need be.
Many things give off electromagnetic radiation. Cell phones, the body, x-rays, and supposedly ghosts and spirits. EMF detectors (or electro-magnetic-field detector) are also supposed to pick up electromagnetic radiation given off by anything it's pointed at.
Probably yes. I have a titanium hip implant that always sets off the metal detectors at airport security. We are talking about a large implant going through and advanced detector. If you are using a basic detector and looking for a wedding ring or something small I would doubt if it would set it off. Titanium is a nonferrous metal.
All cell phones give off varying degrees of radiation.
Radiation
No, foil is a metal and will just make it even more noticeable to a metal detector.
Does the Apple I watch give off radiation
