Alpha particles stop in a sheet of paper, so only a tube with a thin mica window can count them. These counters use either a flat pancake tube, which covers a wide area and finds surface contamination quickly, or a smaller end-window tube. They are the right tool for checking surfaces, radium dials, mantles and mineral samples up close. The window is fragile, so keep the cover on when you aren’t measuring. Prices run from about $300 to well over $1,000, and the most expensive meters are not always the most sensitive.

- GQ GMC-600 Pro#1 of 7Full review
The best value alpha-capable counter, with the same pancake tube as meters costing twice as much. A strong pick for checking surfaces, glass and minerals.

A well-built pancake survey meter for contamination checks and collectors. It is good, but it is expensive for what the tube delivers.

A trusted professional pancake meter for contamination surveys. It is worth it if you need the name; the GQ GMC-600 Pro does most of the same for far less.
