Radionuclides
THYRSIS takes into account radioactive decay and specific activity of radionuclides. Radioactive decay is used in radionuclide transport simulations and specific activity is used for concentration to activity conversion.
These values are read from the elements_chimiques table, which can be filled by using the following command :
python -m thyrsis.database.load_chemicals radionuclides.csv
The radionuclides.csv
file is provided in the thyrsis/tutorial_data
directory. It is a csv file with ;
separator and the following sorted columns:
name
period
atomic_mass
radioactive_decay
specific_activity
water_quality_limit
atomic_number
masse_number
