Cloud Chambers - QTQ

See this sheet for activity & notes - what to do - make notes about the design features of cloud chamber and what they do. Describe HOW the vapour trail (cloud) forms along the radiation path. Compare and explain the trails left by alpha, beta and gamma radiation.

Update - here is the clip I REALLY wanted you to see. Seeing how the Radon gas moves through the chamber is a) Awesome  b) A nice insight to how tracers work

And here is a link to the description of the mosquito killing laser system - nothing to do with cloud chambers though.

And while we're off the topic - here is a link to slow motion footage of what happens to stuff when you shoot it with a .50 Cal round.
