How about Angle in situ applicability?

Angle is suitable for in situ measurements, e.g. for the determination of soil surface or in-depth contamination. An appropriate geometrical model/description should be applied to achieve that aim. For instance, a soil surface can be described as an infinite disc source, which practically means a couple of meters of diameter if the detector is put upside-down just above it (the rest does not contribute tangibly to the measurement), as is common in this type of measurement. In-depth contamination can be calculated by considering the soil as an infinite slab of a certain thickness (again, in practice, it is sufficient to take into account only a couple of meters around the detector).

I intend to study error propagation functions in quantitative gamma-spectrometry. How can Angle help me?

Angle is a great tool for automating your study. All files in Angle 4 are based on the XML format. You can modify or create them from your software. You can run them manually or automatically, using the command line parameters.

The easiest way, in your case, is to create one set of calculation parameters file in Angle, load it in your software and then just change the parameter(s) you want.

Can I use Angle to improve/optimize my laboratory performance?

Of course, based on thorough error propagation studies, for which Angle is ultimately suited, you can improve/optimize your laboratory output/performance

I am lecturing gamma-spectrometry to undergraduate students. How can I use Angle for this?

Angle is a great educational/training tool, as practically all relevant notions are grouped/systematized/visualized – either in the data input phase, or in the output.

Fully functional Angle will thus surely be enjoyed both by students and lecturers. Even a demo version (with 8 demo detectors of most common types) can be used for teaching purposes.

Therefore, numerous universities worldwide have been Angle users from its beginnings.

I am a Ph.D. student in radioecology. How can I benefit from Angle?

Angle is useful at all educational levels, from lecturing gamma-spectrometry fundamentals, to extensive scientific studies. Its modular character enables it to be easily integrated with most sophisticated third-party software, both for input and output. We recommend reading further in the Literature [3], [8] and [9].

Our lab has very limited resources and we cannot afford to purchase Angle. Can we still use it somehow?

You can use Angle in demo mode. It is fully functional, only efficiency calculation is disabled. However, even calculations can be done with a number of demo detectors. Using this option, with some additional effort, you can estimate to a certain extent your actual detection efficiencies, and hence your source activities.
