Geiger Counter Resuscitation

My son and I found this geiger counter at a surplus store, and I just could not resist.  It was pretty rough as the batteries had leaked some years back and caused much internal damage.

Rust and corrosion put holes in the case and destroyed the battery terminals.

But when it was rigged up to bypass the destroyed battery contacts and tested, the unit functioned like a trooper.  It has a small radiation source for testing on the side in a foil sticker.  (don’t sleep with one of these next to your head by the way.)

And here is the indicator showing the readings.

The audio plug even works when you plug in a headset or powered speaker.

I would attach a movie file, but it seems like a lot of data just to see the dial move and hear a bunch of clicks.

So it is off to the electronics store to see what new battery contacts can be found to work with these existing plastic battery brackets.  The only real question is what category to file this under since I don’t have a NBC category (Nuclear, Biological, Chemical).  It hardly qualifies under home improvement.  Well, why not label it just what it is…a new category.

  1. Cool! I don’t know what you’ll use for other than an awesome science experiment. Maybe you could decorate with it?? 🙂
