Geiger Muller Tube, F2-5135.70, £189.00
Our Geiger Muller Tube can be connected to the digital inputs of either the ALBA Logger or TSA+GM Counter.
This sensor connects directly to the digital input on the ALBA Interface and Logger. It has a 9mm window and is capable of measuring alpha, beta and gamma radiation.
There are two Applications on ALBA Disk 4 which can be used with the GM Tube: Counter and Ratemeter. On Disk 5 there is an Application for studying Half Value Thickness.
Connected to a laptop makes this setup portable and offers the potential for some interesting work outside the classroom.

The GM Tube can now be connected to TSA.
The latest mode to be added to TSA is the GM Mode which has three sub modes:
Ratemeter: for studying the properties of alpha, beta and gamma sources.
Counter: displays the counts/minute and can be measured every 1, 2, 5, 10, 15, 30 & 60 minutes.
Up to 100 readings can be stored and they remain in memory after power down.
The statistics available are: maximum, minimum, number of readings and average.
Period Count: this displays the number of counts in 1, 2, 5, 10, 15, 30 & 60 minutes.
This is useful when studying very low levels of radiation from substances e.g. walnuts.
An unexpected bonus: using the Ratemeter mode a signal generator can be calibrated up to 49kHz with an accuracy of plus or minus one Hertz.
