Light snow in Seattle and this message from Aperture Science remind us that the holidays are here!
I’m happy to announce that I have a limited quantity of Geiger Counter kits in stock – just in time for the holidays. You can order one here.
(PS. Rescue Shields are in stock too.)
How do you calibrate the Geiger counter, please?
Jo,
Lots of good info here:
