Geiger counter, an Uncommon card

The card carries these facts from its Wikipedia article.

• It is widely used in applications such as radiation dosimetry, radiological protection, experimental physics and the nuclear industry.
• It detects ionizing radiation such as alpha particles, beta particles, and gamma rays using the ionization effect produced in a Geiger–Müller tube, which gives its name to the instrument.
• In wide and prominent use as a hand-held radiation survey instrument, the Geiger counter is perhaps one of the world's best-known radiation detection instruments.
