Thats an easy one, the answer is Knowledge. Even an Idiot knows that something with teeth spinning at 1000's of rpm's will indeed rip your arm off. Heh Heh. But what you can't see or feel is a whole nother matter.
The problem with even LOW output systems is that it doesn't take much of anything to really bite you if you grab it.
Just think of Ir192. 1 Curie 5.9R per hour at 1 foot.
@6" @3" @1.5" @.75"
23.6 94.4 377.6 1510.4
Thats 1510R per hour and you still haven't touched it. Thats what .419R Per second. So at about Just over 1/4" you're up to 1.6R per second. ....
Now granted Ir192 has a usuable energy of 1.3Mev so lets look at a tenth of that 130kv you're at .16R per second and still haven't touched it.
Thats the real issue with hobbiest, is do they really know what they're dealing with? and do they have the respect they need?
I found a site running around here somewhere where some IDIOT published how to build one and went on to show the xray he'd shot of his foot, Hold it, not just the xray of his foot, but the second one he'd shot to boot.
Now I flat out have no idea what R factor poloroid film needs to get a decent image, and lets face it you can get something like 18R to the extremities but still ....
I fgiure I've got a ton of training and experiance to keep me safe.
