Experimental data and Jupyter notebooks supporting the article "A biomimetic approach to shielding from ionizing radiation: the case of melanized fungi". The repository folder: experiments contains the recordings from the shielding experiments. The directory name is the date the data was recorded. The files are ASCII text at the native output of WinSPEC for Inspectors format (see supplier website for more information). geant_apps contains the Geant4 applications and output files from the simulations. Any application can be compiled and installed using cmake, similar to the Geant4 examples. python contains the Jupyter notebooks to produce the figures and the tables on the aforementioned article. To compile the Geant4 applications, an installation of Geant4 is needed. The results in the repository were obtain using Geant4 10.5.
