Radiation, more specifically the number of free, charged particle in an area. The unit of measurement that it uses can vary depending on the settings of individual counters.

He created the geiger counter, which measures radioactive activity.
The Geiger counter was originally invented by Hans Geiger. The Geiger counter is a device that measures the relative radioactivity of a sample.

A geiger counter measures radioactivity.
Levels of radioactivity are measured by a Geiger counter. Hans Geiger and Walter Muller created a practical radiation counter in 1928.
A Geiger counter.
A Geiger counter, also called a Geiger-Müller counter, is a type of particle detector that measures ionizing radiation. They are notable for being used to detect if objects emit nuclear radiation.
A geiger counter measures radioactivity. It detects the emission of nuclear radiation from alpha particles, beta particles, and gamma rays.
This device is called a Geiger Counter, or sometimes a Geiger-Muller counter, which measures alpha particle concentration. It was developed by Hans Geiger and Walther Muller in the early 1900's.
