The Vernier Radiation Monitor detects alpha, beta, gamma, and X-ray radiation. Applications include nuclear counting statistics, shielding, and decay rate measurements.

 

The Vernier Radiation Monitor consists of a Geiger-Mueller tube mounted in a small, rugged, plastic case. It requires no battery, getting power from the data-collection interface. A thin window protected by a metal screen allows alpha radiation to be detected, along with beta and gamma. It can be used to explore radiation statistics, measure the rate of nuclear decay, and monitor radon progeny.

Use the Digital Radiation Monitor to monitor alpha, beta, and gamma radiation for explorations in radiation statistics, measuring the rate of nuclear decay, and monitoring radon progeny.

 

The Digital Radiation Monitor consists of a Geiger-Mueller tube and a digital rate meter mounted in a small, rugged, plastic case. The unit is battery operated and can be used with or without an interface for measurement of alpha, beta, and gamma radiation. When used with an interface such as LabQuest, it can be used to study counting statistics, inverse-square relations, shielding effects, and other quantitative experiments. Without an interface, use the built-in counter and timer to measure count rates.
