Advanced Scoring of Cs-137 in air

Dear FLUKA Experts and Fluka colleague group

q. Which card can be used to detect a radioactive material travel in moving air with velocity V (cm/sec)

Clarification: As shown in the following figure
I would like to simulate and calculate Cs-137 at point A far from a chimney at distance X at height from ground H.
This problem is simply a travelling a radioactive material in air. But My problem is how I take into account the velocity of air during this simulations and what card can help in this topic.
best regards

Dear @mohammed.fayiz,

Unfortunately, this cannot be done in Fluka.

Many thanks Amario for this fast answer
