Wellcome to The Geiger Counter Catalogue

This site introduces wide range of radiation detector / personal dosimeter catalogues including geiger counter, and any radiation detector related news and its basic knowledge.

Unfortunately, this site is all in Japanase. You can enjoy the site letting "Google Translator" interpret it or looking at the catalogue may give you a rough idea.
