Geiger counters are used to detect beta radiation and gamma radiation. The sensor is a Geiger-Müller tube, an inert gas-filled tube (usually helium, neon or argon with halogens added) that briefly conducts electricity when a particle or photon of radiation makes the gas conductive. The tube amplifies this conduction by a cascade effect and outputs a current pulse, which is then often displayed by a needle or lamp and/or audible clicks. Modern instruments can report radioactivity over several orders of magnitude. Some Geiger counters can be used to detect gamma radiation, though sensitivity can be lower for high energy gamma radiation than with certain other types of detector, because the density of the gas in the device is usually low, allowing most high energy gamma photons to pass through undetected (lower energy photons are easier to detect, and are better absorbed by the detector. Examples of this are the X-ray Pancake Geiger Tube).

Round-up: Interesting Gara-auction pics

Nicely finished build-up of a Volks Orient Hero Jr. garage kit; these shots really highlight the oddly sloped nature of the head sculpt on this one:

Not sure who produces this funky, timid little pre-paint... packaging makes me think it could be X-Plus...?


Vehicular Pygmoncide


A little bit Antiques Roadshow, a little bit Win, Lose or Draw

Check out this interesting segment from a game show, featuring a Bullmark Gary (great little clip of super-excited Pygmon from "The Little Hero" up front):

I really must, must move "Learn Japanese" way up on my (quite epic) to-do list...


Love this Pyg-painting

Dig these crazy brushstrokes, kids:

(You may have noticed that the greyscale version of this piece is the new Garamania header... or maybe you didn't, I dunno... it's kinda inconspicuous...)

From here; I thank the artist for this kool kontribution to Gara-kultur!
