[R-390] IMPORTANT International meter disassembly

Mon, 23 Sep 2002 07:10:35 -0400

The MOST important thing that is what Helm forgot to
tell you.
OPENING THE METER WILL POTENTIALLY 
EXPOSE YOU TO RADIUM DUST WHICH CAN
HAVE LONG TERM HEALTH RISKS.  ONCE YOU
INHALE A SPECK, IT SETTLES IN YOUR BONES AND IS THERE TO STAY.
The meters can be safely disassembled but you must use
common sense.
