The Radalert 100 Digital Pocket Geiger Counter

The successor to the proven and popular Radalert 50, the Radalert 100 is a digital pocket Geiger counter designed for general purpose monitoring of radioactivity.

It detects Alpha, Beta, Gamma and X-radiation, visually shown on a highly accurate digital display with readings in your choice of both CPM (to 110,000 counts per minute) and mR/hr (up to 110 mR/hr), or switchable to the international standard of Sv/hr (up to 1,100 uSv/hr).

 

 

 

A red LED blinks and a beeper chirps with each radiation count.  The audio chirp can be turned off.

The Radalert derives its name from an audible alert that sounds when the radiation reaches a user-adjustable level.  Play this sound file.  The picture at right shows that adjustment on the top of the unit, to the right of the screened open window over the Geiger Mueller detector.

The Radalert 100 also can be set for a Total Count , which will accumulate the radiation counts over time.  This is a useful feature especially for establishing your background radiation level.   As an example, you can set the unit to Total, and after say 10 minutes, divide the Total Count value by 10 to arrive at your background radiation in CPM.

This unit also has a Data Output port to record counts on a computer or data logger, as shown in the picture at right.

The Radalert 100 runs on a single 9 volt alkaline battery (included) which will last up to three months on continuous use at background levels.

The Radalert also comes with a padded vinyl carrying case with belt loop, shown at left.
