Dear Vittorio,
i have a question about the scoring in FLUKA. In some of my simulation i set this score:
USRBIN type: REGION part: DOSE-EQ , selecting the region of the geometry that i want to study.
At the end of the simulation, in the section Files of the RUN window i open my usrbin plot and i see two values.
I send you an image to well understand. I'm not sure about the meaning of these values.
My idea is that the first value (9.83192e-08) is the average value of the quantity dose-eq in the region i'm studing. Is that right?
The problem is the second value (0.0150946). What is this value?? Could it be a kind of standard deviation or a percentage error?How does FLUKA calculate it?
Thank you very much for your help,
Best regards
Francesco

Dear Vittorio,
following your instructions, i was able to import the icrp phantom on fluka and run
succesfully some simulations but i have a question about the plots that i obtain from simulations. I'll send you an image of what i'm talking about. In detail, in every plot i did, there is a parallelepiped cage sourrounding the phantom. I think this cage corrispond to region VOXEL in the geometry, and fluka manual (page 298) says that this region VOXEL is a sort of cage for all the voxels of the model. According to the manual I assigned to this region the material vacuum. I also assigned air and other materials to the phantom but everytime i do the plots i see this cage contour around the phantom.
Do you know if this cage, that appears like a discontinuity, can affect the results of my simulations or it is just a problem of visualization due to the import of the model in fluka?? The plot is an energy usrbin.
Thank you very much for your help,
Best regards
Francesco

Hi Matteo,
If you are new to Fluka I would suggest you to go thought the course material to get familiar with the lingo and the feature of the code.
About the ICRP, check those two threads:
http://www.fluka.org/web_archive/earchive/new-fluka-discuss/9282.html
http://www.fluka.org/web_archive/earchive/new-fluka-discuss/3364.html
Please read the thread, here you might find also some chunk of code which might expo you on the way:

Best

Dear Fluka Experts,
I'm an engineer and in this period I'm working on my thesis with Fluka. In particular, my project is about the validation of a shielding material and then use this material to set up a dosimetric analysis on a human phantom. My problem is just on the construction of the phantom.
The models that I have to use are the adult reference phantoms from the ICRP publication 110.
I chose the male model, that is made of the following files:
- AM.dat
- AM_blood.dat
- AM_media.dat
- AM_organs.dat
- AM_spongiosa.dat
My question is: how can i use all these files to built a full complete phantom ( with all organs..) and import it in Fluka??
I understand that the way is the voxel conversion and i also found on the fluka manual a program but I don't know how to work in the correct way.
Can someone guide me ?
Many thanks for considering my request and for the support.
Best regards
Francesco Di Matteo
