[time-nuts] beryllium oxide

[Tom Clifton]

Also used on old "lighthouse" tubes used for uhf and low microwave applications fro the '40's and '50's.  If my memory serves me, these tubes were found in devices like the airborne APX-6 IFF Transponder in which the greatest hazard was the detonators used to destroy the device should a plane go down over enemy teritory...

An instrucor in the 70's made sure we were paranoid about both the berylium oxide and explosives...
