  radioactivedecay is a Python package for radioactive decay modelling. It
contains functions to fetch decay data, define inventories of nuclides and
perform decay calculations. The default nuclear decay dataset supplied with
radioactivedecay is based on ICRP Publication 107, which covers 1252
radioisotopes of 97 elements. The code calculates an analytical solution to a
matrix form of the decay chain differential equations using double or higher
precision numerical operations. There are visualization functions for drawing
decay chain diagrams and plotting activity decay curves.
