Product Details

The PASCO Wireless Geiger Counter counts beta, gamma and alpha radiation particles as they enter the Geiger–Müller detector tube inside the counter. Designed for easy mounting, the Geiger Counter provides superior position control in inverse square law labs, as well as an audible beep to indicate the detection of ionizing radiation.

With the Wireless Geiger Counter, students can wirelessly control the high voltage supplied to the Geiger–Müller tube inside the counter, enabling them to make measurements of counts/interval for different tube voltages. They can also plot counts/interval versus tube voltages to experimentally observe the Geiger plateau characteristics of the tube.

• Built-in metal mesh screen to protect the delicate mica window in the front of the Geiger–Müller detector tube

• Audible beep count indication that is easily switched on or off

• Versatile positioning options: either in the PASCO Sample Holder, hand-held, or mounted on a rod stand

• Provides wireless control over the high voltage supplied to the Geiger–Müller tube inside the counter for Geiger plateau experiments

Included: Wireless Geiger Counter (1); USB Cable (1); and a Threaded handle for mounting the sensor to a rod stand (1).
