Normalization with Multiple source

Source Definition
1

Dear expert,

I am trying to get the dose rate distribution using multiple source settings according to following post.
In the input file, scoring DOSE-EQ with USRBIN card, all the sources are sequentially equal.

* ..+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
SPECSOUR          6.        2.                                        BEAMSPOT

My question is:
1.What’s the unit in output file, still pSv/primary?
2. Should i multiply the total source numbers to get final dose distribution? Or the result is exactly the final dose distributuion?

Best regards,
honghu

Dear Honghu,

  1. Using the SPECSOUR card with BEAMSPOT option does not change the unit of quantities, so DOSE_EQ is still [pSv/primary].

  2. Yes, you need to multiply the results with the total intensity of all your beams.

Dear David,

Thanks for your reply!
So if all beam intensity are equal, I need to normalize the result with this :
result * number of sources * beam intensity.

Dear Honghu,

yes, that is correct.

Cheers,
David
