[Gate-users] Citation for spleen material definition used in examples?

[Matthew Belley]

Dear All,

I would be grateful if someone could point me to the citation or source
that was used to derive this material definition:

/example_Radiotherapy/example3/data/GateMaterials.db lists Spleen as:


Spleen: d=1.06 g/cm3 ; n=11
        +el: name=Hydrogen  ; f=0.103
        +el: name=Carbon    ; f=0.113
        +el: name=Nitrogen  ; f=0.032
        +el: name=Oxygen    ; f=0.741
        +el: name=Sodium    ; f=0.001
        +el: name=Phosphor  ; f=0.003
        +el: name=Sulfur    ; f=0.002
        +el: name=Chlorine  ; f=0.002
        +el: name=Potassium ; f=0.003
        +el: name=Calcium   ; f=0.0
        +el: name=Scandium  ; f=0.0

I notice it is very close to the ICRU-44 soft tissue and blood definitions,
but it is not identical:

Thank you,
