[ RadSafe ] Building a miniature x-ray tube

[Cary Renquist]

In the comments, there is a reference to a Russian kid that did some
experimentation with a x-ray tube several years ago...
I remember him -- he had an ion chamber and sounded like he knew what he
was doing, but ended up spending quite a bit of time in the hospital.
They figure that at least one finger received ~20-25 Sv -- it is not
clear from the google translation, but it sounds like the finger
recovered ok.

On the third day after exposure, the experimenter turned red leather
index finger on his right hand by January 6 increased redness, swelling
of, unpleasant sensations in the fingers. Later, the flat blisters on
the tips of the fingers of the right and left hand. As a result, the
index finger has formed a radiation burn Grade III-IV. Fortunately,
physicians as a result of active vascular therapy to preserve the
function of the hands.

As explained in the Federal Medical Biophysical Center named after AI
Burnazyan the Federal Medical and Biological Agency, the maximum dose
exposure came in the second finger of his right hand and reached 20,000
25000mZv, the remaining fingers of his right hand and left hand - below
2,000 mSv.

Quite an impressive craftsman, though I would have appreciated at least
a
millimeter or two of lead shielding between him and the assembly.
