ISOTOPIA

ISOTOPIA is a software package for the prediction of radio-isotope production. It uses cross sections from the IAEA medical isotope data library and the TENDL nuclear data library and calculates the radioactive yield as a function of irradiation time and other irradiation characteristics.

Documentation and reference

A description of the code and its options can be found in the ISOTOPIA User Manual (pdf). The reference to be used for ISOTOPIA is

A.J. Koning, D. Rochman, J.-Ch. Sublet, N. Dzysiuk, M. Fleming, and S. van der Marck, TENDL: Complete Nuclear Data Library for innovative Nuclear Science and Technology, Nuclear Data Sheets 155,1 (2019).

Installation

Prerequisites:

The following are the prerequisites for compiling ISOTOPIA:

• git (only if the package is downloaded via Github)
• a recent Fortran compiler such as gcc (gfortran)

Downloads:

To download ISOTOPIA, you can use one of the following options:

1. Download the entire tar file (frozen version):

https://nds.iaea.org/talys/isotopia.tar
tar zxf isotopia.tar

2. Using git (latest beta version):

git clone https://github.com/arjankoning1/isotopia.git

The ISOTOPIA sample cases do not fall under the git repository. For that you need to download:

https://nds.iaea.org/talys/samples/isotopia_samples.tar
tar zxf isotopia_samples.tar

The resulting samples/ directory should be moved to the isotopia/ directory.

ISOTOPIA requires the cross section database isotopia.libs/ This can be obtained as follows

https://nds.iaea.org/talys/codes/isotopia.libs.tar
tar zxf isotopia.libs.tar

and place the resulting directory isotopia.libs/ in your home directory.

Installation instructions:

To install ISOTOPIA, you can use one of the following options:

1. Using make:

cd isotopia/source
make

2. Using the install_isotopia.bash script:

cd isotopia
install_isotopia.bash

The above will produce a isotopia executable in the isotopia/bin directory. The compiler and its flags can be set in either the source/Makefile or in code_build.bash.

The ISOTOPIA package

The isotopia/ directory contains the following directories and files:

• README.md is this README file
• LICENSE is the License file
• install_isotopia.bash, code_build.bash and path_change.bash installation scripts
• source/ contains the Fortran source code of ISOTOPIA and the Makefile
• bin/ contains the executable after successful installation
• files/ contains abundance and decay data files needed for the calculations
• doc/ contains the tutorial in pdf format
• samples/ contains the input and output files of the sample cases, and the verify script for the user to run the sample cases

In total, you will need about 50 Mb of free disk space to install ISOTOPIA.

Sample cases

A successful installation can be verified by running the sample cases. For each sample case, the results are written to a subdirectory new/, which can then be compared with the output provided in the ISOTOPIA package in the subdirectory org/. The entire sample set will take about 1 minute.

cd samples
./verify

ISOTOPIA works as follows:

isotopia < isotopia.inp > isotopia.out

assuming that isotopia is linked to the isotopia/bin/isotopia executable.
