We can't run Cs-137 and I-131 at the same time, right? Thank you

Yes, you can run with multiple species. In the Concentration Setup menu 1) click on the Pollutants, Deposition, and Grids setup button; 2) under pollutant change =1 to =2; and 3) click on specie 1 and specie 2 under pollutant and deposition to configure the emissions rate and deposition properties for the two species.

You can run multi radioactive nuclides in two ways.
1) As Chris suggested, set multiple pollutants with each decay rate.
2) Run the simulation for radionuclides and noble gases without decaying rate. Apply decay rate later using a post-processing tool. This is what Roland showed in 15.3, and it can save simulation time for the multi-species run.

Thank you!
