[R-390] meter luminescence

[rbethman]

The idea of Plutonium on dial faces is absolutely absurd!

It takes a Uranium fissile process to create Plutonium - period.

The radioactive material - Plutonium - is HIGHLY radioactive and WILL 
remain so for some 24 ** (4) or longer.  IOW - 24000 years for the 
half-life.

The military has NEVER used such.  The only radioactive elements used, 
have been Radium, and Tritium.
