Hello, I am a total beginner. I am trying to define Cs-137 as a point source, but could you help me with how to define its activity?

Dear Yıldız,

I would recommend you to go through the material of a previous FLUKA course:

You will find the answer to your question on slide 35 of the Radiation Protection and Activation lecture.

Cheers,
David
