GM-45 Radiation Detector



This page is displaying the output from two GM-45 units which are connected together and operating in "Coincidence Detector" mode, more information can be found here, Coincidence Detector and here, Blackcat Systems

This LINK is an Accumulated Chart spanning the last 3 Days of data collected by the Blackcat server.

The GM-45 is a Alpha / Beta / Gamma detector with a large pancake tube for higher sensitivity.

The Pierre Auger Observatory is a site worth visiting for latest research in Cosmic Ray detection.

This LINK will also provide plenty of information on Cosmic Ray Detection including a link to various You Tube clips of interest showing Cosmic Ray Detectors in action, thanks to Robert Hart for allowing us to link to his page.

This is a Direct Link to one of Robert's Pages about Cosmic Rays, at the bottom of the page is a delightful video clip of Carl Sagan talking about Cosmic Rays as only he can do it!.

It is still planned to build a Cosmic Ray (Muon) detector as a project which can be added to LMRO. The GM-45's are ultimately to be used as Reference units.


The GM-45 Program allows the station to be placed on a Map of the World together with other Radiation Detectors around the world, this link:- On Line Geiger Counter Nuclear Radiation Map will take you at first to a map of the USA, use the Zoom Out controls to view the World, the 'number' over LMRO is our station and is indicating the average Counts Per Minute being detected, by placing your pointer either side of the number and clicking on it will take you to the 3 Day Chart, the map page refreshes every 15 minutes.


The LMRO detectors were commissioned on the 3rd of September 2011.

Below are just a few stations operating Radiation detectors
