National Radiation Instrument Catalog ™
1920-1960
The National Radiation Instrument Catalog began in October 2001
as a project to document every portable nuclear radiation detection
instrument developed over the four decade period from 1920 to 1960.
This site was established in October 2007 to share information with
those interested in the history of portable radiation detectors.
This project is on-going......
