Home-Made Geiger Counter with *RARE* Mini LND-71436 Tube. WORKS Radiation Tesla

Description

I built this
Geiger Counter using a
very rare
LND-71436 miniature Geiger tube
.
The LND-71436 is a miniature gamma Geiger tube designed for military radiacs meant for high-dose-rate counting (1.5cps/mR/hr).
The Geiger counter works on either a standard 9V battery, or an external 9VDC source.  Has an internal clicker, and can output TTL pulses for each count.
Tested, works great.
