Industrial Metal Detection Ideas?

Ever seen the metal detector in "Total Recall"? ;-P

Cheers! Rich

No, not unless you are a long way from anything that can be damaged.

The way it is solved normally is to have whatever you're examining run along a conveyor belt through a lead lined tunnel with multiple flaps of lead-rubber to seal the ends. It's like an airport baggage checker but the x-rays are form the side.

The approvals system isn't that onerous. The equipment needs to be safe and you need to be able to prove that it is safe. The dose rates for fluoroscopic techniques are very low so it is fairly easy to achieve.

Well, if it's properly designed then you won't get a jam. If it did happen I think you'd probably want to turn off the conveyor and the x-rays before diving in.

There would be no risk to the guy loading the conveyor belt.

Hello Graham,

It's not as bad as for medical gear. But is often depends on the state you are in. We live in an over-regulated one :-(

You wouldn't believe it but when we lived in Germany and bought the first microwave oven a guy from their counterpart of the FCC had to come out and "bless the installation of an RF power source".

There'll always be jams. Too long a branch drifts sideways, loud screeching of wood against metal, pile building up behind it. Some wood like that from a diseased pine tree can be extremely sappy and that gets stuck a lot.

As to turning off the motors, you know how things can go when people work on fixed bids...

Yes, he may be far enough, depending on dosage. However, you can't really close off the top of the conveyor. And when some regulatory folks say that there shall be a shield and there is none they'll shut it down. Whether or not the dose of radiation is much less than what comes from the sky wouldn't make any difference to them. They go by their book.
