[R-390] R390A meters

[Dave Merrill]

I have two 67 contract EACs and both have non-radioactive meters, verified
with a Ludlum Model 2 Survey Meter.
The Carrier meters are marked 59.7289 and the Line Level meters are marked
59.7290.  All these meters glow bright green when exposed to a UV source.

I also have an older R-390A and both meters have had the Ionizing Radiation
Symbol sticker applied.  The Ludlum goes nuts when brought close to the
glass on these.
