Re: [fluka-discuss]: Dose calculation (Unit: Gy/min)

Hi HoSeung,

Results are normalized per primary (in your case per incident electron).

Thus, to normalize your results per minute you need to multiply those by 7.5E12 x 250 * 60:

Results 7.5E12 e 250 pulse 60 s
----------- x --------------- x --------------- x -----------
      e pulse s min

Please note that Gy is the unit for absorbed dose density [J/kg], so you should score it in your target of interest, not in air (unless you want to know the absorbed dose in air).

Subject: [fluka-discuss]: Dose calculation (Unit: Gy/min)

Dear Fluka users,

I am conducting a simulation with 15 MeV electron beam to tunsgen target to generate photon and neutron. After the target, I put conical shape collimator to focus the photon. I want to calculate a photon dose (Gy/min) at the certain distance from the target (example: 1m, 2m, 3m and etc.).

1. For a input card, I used USRBIN (dose-eq), AUXSCORE (photon) to score the photon equivalent dose, and the unit is pSv/primary. Is this true?

The specification of the accelerator is as follows;

- number of electrons per pulse: 7.5*10^12
- pulse frequency: 250Hz
- pulse duration: 6us

With these parameters, I want to calculate a photon-dose (Gy/min) with FLUKA. I am a beginner of this program and this field. Can you tell me how to calculate Gy/min at certain point (or surface) with a little bit detail?

Thank you in advance.

Ho-seung SONG
