Tools for radiation spectral analysis.
Becquerel is a Python package for analyzing nuclear spectroscopic measurements. The core functionalities are reading and writing different spectrum file types, fitting spectral features, performing detector calibrations, and interpreting measurement results. It includes tools for plotting radiation spectra as well as convenient access to tabulated nuclear data, and it will include fits of different spectral features. It relies heavily on the standard scientific Python stack of numpy, scipy, matplotlib, and pandas. It is intended to be general-purpose enough that it can be useful to anyone from an undergraduate taking a laboratory course to the advanced researcher.
pip install becquerel
Features in development (contributions welcome!)
- Reading additional
Spectrumfile types (N42, CHN, CSV)
Spectrumobjects to various standard formats
- Fitting spectral features (e.g., gaussian lines with different background models)

(It is more convenient to use
develop so that the code is soft-linked
from the installation directory, and the installed package will always use
the current version of code.)

To run the tests using
pytest, from the root directory of the repo:
python setup.py test is still supported also.)
By default, a code coverage report is printed to the terminal.
