Thats not her hand, from the way I read it, it was just a "this could happen" picture.

I believe rp181s statement is correct. From what I was told by Stella, she has kilos upon kilos of lead shielding and has been the driving force behind x-ray safety for as long as I have been here(dosimeters etc.), she has quite some x-ray experience from what I gather. I am sure that, the picture she posted was a warning.

BTW: Whatever you do, don't be this guy: Link2 :O :O :O (I only hope he was not in the room what the x-ray was blasting)

Is 60kV a figure that you have just plucked out of the air? Let's suppose your anode is of Mo (as very likely it is) You'll see from the graph there's not a lot of point in driving the tube with more than 20kV, just for a bit of extra Bremsstrahlung (braking radiation) You'll see from the graph there is nothing whatever to be gained from increasing kVp from 40 to 60.



Good Luck! smile


So for normal xray tubes (medical, dental) they are using xrays from ionized inner shells in order to take pictures? This characteristic radiation should be isotropic whereas the bremsstrahlung would be peaked at some angle depending upon the gamma of the incoming electron beam. The only kind of xray systems that I am familiar with are much higher voltage flash xray sources which use bremsstrahlung as the xray source.
