Re: I X-Rayed my Apple IIe

I must admit to feeling some revival of the desire to build my
own X-ray machine.  But I thought that modern CCDs had drastically
reduced the "dosage" required to get an exposure.  The several-
hundred-RAD territory sounds a bit out of my range.  ;-)



It was several hundred rad for 16 or so full exposures.  The exposure
required depends on the pixel size.  That was quite a high resolution
x-ray.  ;)

That said, 80kv 6ma is hardly anything.  The tube I was using goes up
to 160kv 20ma, and it isn't our biggest tube.  We have a tube that goes
up to 420kv and 10ma.  THAT is a high dose...

I imagine that an old AM radio tube could make some crude x-rays...  Or
you could buy an x-ray tube off of ebay.  : )


I just found a nice link describing X-rays made with an 80kV dental
X-ray machine (from eBay) on Polaroid 600 color film:

and another describing a homemade machine using a flyback transformer
and a Cockroft-Walton multiplier, applied to a receiving tube
(both immersed in oil):

Looks like we were thinking the same way...  ;-)
