Can the Abacus be used to detect gamma only?
When the Abacus is using one of the exposure rate measurements (µR/h, mR/h, µSv/h) then only the internal peanut tube is being used. Since the peanut tube is too thick walled, as well as surrounded by the case and a little air space, there is a very negligible beta and alpha response.
What are the different types of swipes available in the GammaPAL?
There are two types of swipes that are for use with the GammaPAL; Air swipes and Wipes for surfaces. The GammaPAL includes wipes for surface testing and are able to be used with either The Inspector and Wipe Test Plate (included with The GammaPAL) for quantification or for use with the GammaPAL sampling matrix for […]
Why are there two different times on the LLD graph on the GammaPAL page?
The Japanese standards are based on the Critical Detection limits (50% confidence level) and are able to be reasonably achieved based on a 600 sec background sampling time. The Standard MDA limits (95% confidence level) need the longer 900 sec time to achieve reasonable results.
I am trying to use the Observer Software (Gateman Version) with the Gateman, but I’m not receiving any counts from the unit on my computer. How do I set it up?
The Observer Software (Gateman Version) works with the RS-232 jack on the end panel of the instrument (to the left of the data out jack). The Gateman must be in “Terminal Mode” for the instrument to send data. You can turn on “Terminal Mode” in the Gateman menu. Normally, the Observer Software uses the pulses […]
The Geiger has no LCD readout. How do I tell what my readings are?
You have to connect the Geiger to a computer via serial cable (provided with the Observer Software) to be able to rad what information it has collected.
