Geiger and Müller: electron-counting tube for very weak activity

What changed

Reported sensitive electron-counting tube for weak ionizing radiation.

Scientific scope

The record is the exact two-author 1928 Naturwissenschaften paper. Geiger’s earlier counters, other 1928–1929 tube papers, later quenching designs and commercial instruments remain separate.
