Are Metal Detectors Safe?

Totally harmless.

May I know how do you come to the conclusion?

They are certainly less harmless than switching them off. After all, who would want an offensive weapon to pass through them <rhetorical question>?

Mostly harmless.

1.Someone can hit you over the head with it. (hand held)

2. Can be strangled with the coil wire.

3. Thats all I can detect now.

I mean the proper usage of Metal detector not as a hammer or as a weapon.

The amount of EM radiation emitted by the metal detectors very low and that also in most of the cases are micro or mili second pulses.

This amount of radiation can not cause any effect on the health at least it is not known.

Search on googel has shown two aspects (Metal detector pass safety test on pregnant woman) -

and

(likely effect on the pateints with transplant - avoid it)

However for general persons - i feel we have too much of concern for everything without thinking as I walk in factory what are the em radiations leaking from so many machines doing to me or the gamm rays and the x rays in my fabrication areas - as i get exposed to the minute doses over years what is my chances of survival to be 150 or atleast 100

What about all those cosmic radiations getting through the ozone hole ?

(remember - poison neutralises poison so may be all these em radiations are mutating my deformed genes back and that includes the smoke that you see in the screen - missed it ? look carefully)

You have a high number of off-topic marks for an answer that is not off-topic in my opinion. I agree and think there is too much ado about nothing.

I dont know how many people answering a post get high levels of "off-topic" for often good responses. Comments anyone?????

Thank you, for your valuable and clear analysis.

While going through Frankfurt Airport security within a year of 911 my pacemaker was detected by the wand and my medical card was not getting it with the security guy who didn't speak English. Tempers were flaring and I was close to punching the jerk until a supervisor intervened and I was eventually allowed to proceed.

So to answer your question, metal detectors have the potential to cause harm.

To your average humanoid primate, magnetic fields as high as 3 and 4 Tesla are harmless. That is the level some research MRI machines achieve. Your average medical MRI operates at about 1 Tesla and the operators are exposed to that for hours upon hours a day. Now pacemakers and such can malfunction or be damaged, and implants like bone screws and such can cause problems, but to a healthy non-modified human, magnetic fields thousands of times stronger than an airport magnetometer can generate are perfectly harmless.

Twenty five years of pacemaker use, (I'm about to get my fourth) experience is

WEARING PACEMAKER...ALWAYS ADVISE TECHNICIAN AND INSIST ON THE HAND HELD

BODY SCANNER...NEVER USE THE WALK THROUGH !!!!!!!!!!!!!!!!

I have never had a bad experience with hand held scanner.

Thank you all for your valuable contribution on the topic.

I have a major paved jogging / biking trail behind my house, I have been toying with the idea of getting a metal detector and scanning for jewelry that falls off of the trail users. I've found 3 pieces just by looking down as I walk, I'll bet there is plenty more in the grass on either side.

Of course they are safe. Metal detectors do no harm to human body.
