X-RAYS FOR INDUSTRY
Do you know that the CATHODE
TUBE is sealed as a vacuum, having a
negative wire (CATHODE) at one end,
and a positive wire (ANOOE) at the
other end? When the electric current is
switched on, electrons stream from the
negative wire across to the positive wire.
When the electrons strike the ANODE,
the anode itself gives off X-rays as they
are called. These X-rays will pass through
most solid objects and are seen at work
here in the detection of flaws in metal.
