The x-ray technicians would
position everything, while wearing these heavy stiff aprons. Then, once they
had moved the sights, inserted the photographic plates, focusing the
cross hairs (on my face this particular time), they would step back behind a
wall with a small window in it, saying, “Hold still”. Then the click, clunk,
Whirr and after a short pause, they would step out again. Supposedly after the
radiation had stopped flying around. It was obvious they knew the machine was not
perfect. They could focus it roughly in the direction of the injury, but there
was still a chance it wouldn’t be quite right. Hence they hid behind the wall.
It always seemed strange to me that there was a window in that wall. Obviously
it must have been made of special glass, which stopped the radiation from
leaking through? Why didn’t they build the whole room like that then. Why did
they have to go and stand behind a wall? Why was I left lying under the arm of
the machine like a modern day sacrifice to the greater power? Something special
about the glass? Or, so you would think. I was told some years later, when
older and curious about the actual mechanics of what they were doing, that
there was nothing special about the glass at all. It was one of those
arguments, that, the radiation was flying around from the machine, the
‘chances’ of it actually passing through the window space was pretty huge.
Chance? I was always told you
don’t take chances, particularly with radiation. The chance of radiation bouncing
through the gap where the window was, was very, very high, but it was possible?
People (particularly the technicians) have to ask themselves about the risk? If
it is like throwing a ping pong ball through a small window on the third floor,
Then that should be fine. Very little chance of succeeding. Until you got it?
Then it wouldn’t be too hard to keep hitting that same spot again and again.
They call that ‘getting your eye in” and if you were talking radiation, then
the idea that the random radiation could follow a specific movement and since
it’s the same head in the window, the technician could be getting it in his
eye!
