Necessity is the mother of all inventions.
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.
Geiger counter was created in 1908.
The Geiger Counter was developed by Hans Geiger.
Geiger counter was invented by the Hans Geiger in 1908.
The Geiger counter clicked as it checked for radiation.

A Geiger counter measures radiation levels by detecting ionizing radiation. When radiation interacts with the gas inside the Geiger-Muller tube, it causes the gas to ionize and create an electrical pulse that is counted by the device.
Levels of radioactivity are measured by a Geiger counter. Hans Geiger and Walter Muller created a practical radiation counter in 1928.
A geiger counter is a measuring instrument, not a measure.
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, also called a Geigerâ??Müller counter, is used for measuring ionizing radiation. A Geiger counter detects alpha particles, beta particles and gamma rays.
