Demonstrations are cataloged according to PIRA Bibliography


Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

Daedalon Geiger Counter


A Daedalon Geiger counter is used to measure the activity of various alpha,beta and gamma sources.


The Daedalon Geiger counter is connected to the room's audio system and counter rate on the device display is projected on the screen with the help of a camera. A set of sources is available to demonstrate count rates of different isotopes. A number of Al, Pb and paper sheets can be used to demonstrate their effect on the count rates.
