See the Buying Guide for this item's required, recommended, and additional accessories.
Product Summary
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. The front plastic snout fits conveniently inside the NU-3344 Sample Holder stand (available separately).
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.
Features
- 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 NU-3344 Sample Holder, hand-held, or mounted on a rod stand
- Convenient design to natively fit the PASCO NU-3344 Sample Holder
- Provides wireless control over the high voltage supplied to the Geiger–Müller tube inside the counter for Geiger plateau experiments
Applications
- Observe the inverse square law
- Measure the Geiger plateau associated with a Geiger–Müller tube
- Demonstrate the shielding properties of different materials and different types of ionizing radiation
What's Included
- 1x Wireless Geiger Counter
- 1x USB Cable

Determining the Relationship Between Distance and Radiation Count
Students measure the radiation count rate as a function of distance. They use their measurements to make predictions about the count rate at other distances. By inspecting the data, they find out the count rate varies by the inverse...
Investigating Environmental Radiation
Students use a Geiger counter to measure the radioactivity of a sample of their choosing. They measure the background radiation to determine if their selected sample is radioactive. For some samples, they can use shields to figure...
Types of Radiation
Students use a Geiger counter to measure the background radiation to calibrate the measurements of radiation source disks. They measure the count through various materials of an alpha, beta, and gamma source. They identify which...
Radioactive Decay and Half-Life
Students measure the counts coming from a sample of Ba - 137m with a Geiger counter. They answer questions about radioactive decay and half-life during the 10-minute data collection time. They use the resulting graph to estimate...
Modeling Absorption of Radiation
Students use a Geiger counter to measure the radiation from a radioactive sample of Sr-90. They use the radiation absorption equation to predict the counts after one aluminum shield is used and find the counts are much higher...
