Use the Vernier Radiation Monitor to explore radiation statistics, measure the rate of nuclear decay and monitor radon progeny.

This easy-to-use sensor consists of a Geiger-Mueller tube mounted in a small rugged plastic case. A thin window protected by a metal screen allows alpha radiation to be detected, along with beta and gamma. Each new detection is indicated by a flashing red LED light and can also include an optional audio signal.
The sensor is powered by the data-collection interface and a battery is not required.

The Radiation Monitor allows students to:
• Detect the presence of a source of radiation.
• Monitor counts/interval (rate) as different thicknesses of a particular type of shielding are placed between the Geiger-Mueller tube of the Radiation Monitor and a beta or gamma source.
• Compare the effect of different types of materials to shield beta or gamma radiation.
• Set up a histogram with a very long run time to show students how initial randomness of data develops first in a Poisson distribution and then into a Gaussian distribution curve.
• Measure radiation of common radioactive materials such as lantern mantels or pre-World War II Fiestaware.
• Monitor variation in background radiation at different elevations.
• Monitor radioactivity in the environment over long periods of time.
• Monitor counts per interval (rate) from a beta or gamma radiation source as a function of the distance between the source and the Radiation Monitor.

• Sensor: LND 712 (or equivalent) halogen-quenched GM tube with a mica end window, 1.5 to 2.0mg/cm2 thick
• Sensitive to alpha, beta, gamma and X-ray radiation
• Powered by interface connection
• Red LED blinks on radiation detection
• Optional audio signal on radiation detection

    This product is used in teaching these Australian Curriculum codes:
    ACSPH030 - Thermal nuclear and electrical physics - Ionising radiation and nuclear reactions - Alpha, beta and gamma radiation have sufficient energy to ionise atoms
    ACSPH029 - Thermal nuclear and electrical physics - Ionising radiation and nuclear reactions - Each species of radionuclide has a specific half­life
    ACSPH028 - Thermal nuclear and electrical physics - Ionising radiation and nuclear reactions - Some nuclides are unstable and spontaneously decay, emitting alpha, beta and/or gamma radiation over time until they become stable nuclides
