Radiation Monitor In Stock Now

The Vernier Go Direct Radiation Monitor senses ionizing radiation by means of a Geiger‑Mueller (GM) tube. The tube is fully enclosed inside the instrument. When ionizing radiation or a particle strikes the tube, it is sensed electronically and monitored by a computer and by a flashing count light. There is an optional audio signal. Radiation is measured in counts in a time interval, as configured in data‑collection software.
