AUXSCORE
allows to associate scoring detectors of given estimator types with dose
equivalent conversion factors and to filter scoring detectors according to
auxiliary (generalised) particle distributions or ion isotopic ranges.
See also EVENTBIN, USRBDX, USRBIN, USRTRACK, USRCOLL, USRYIELD
WHAT(1)
: binning / estimator type to associate the card with
1.0 : USRBDX
2.0 : USRBIN / EVENTBIN (only for binning of quantities scored
along a step, or for activity binnings, see Note 6)
3.0 : USRTRACK
4.0 : USRCOLL
5.0 : USRYIELD
Default
= 2.0 USRBIN/EVENTBIN
WHAT(2)
: particle (or particle family) to be considered as a filter for
the associated scoring card
> -100.0 : particle or particle family code
<= -100.0 Isotope coding (to filter ions). To select atomic
number Z, mass number A and isomeric state M:
WHAT(2)
= -(Mod(Z,100)*100 + A*100000 + M*100000000).
Z = 0 means all atomic numbers for the given A,
A = 0 includes all mass numbers for a given Z,
M = 0 includes all ground and isomeric states.
To select only the ground state set M = 9
Default
= 201.0: all particles (ALL-PART)
WHAT(3)
= i0 + 100 x i1: flag for considering the possible parent for
delta rather than the delta itself (Moller and Bhabha excluded)
when filtering for particle type (see WHAT(2)
), or to exclude
charged products of pointwise neutron interactions from the
scoring in order to avoid possible double counting
i0 = 0: ignored
= 1: the delta parent is used for filtering
= -1: reset to default (=0)
i1 = 0: ignored
= 1: charged products of low energy neutron pointwise
interactions are excluded from the application of
conversion coefficients (default)
= 2: charged products of low energy neutron pointwise
interactions are included in the application of
conversion coefficients
= -1: reset to default (=1)
WHAT(4)
: lower bound index (or corresponding name) of the indices of the
detectors in which the associated scoring is activated (see
Note 1)
("From detector WHAT(4)
....")
Default
= 1.0
WHAT(5)
: upper bound index (or corresponding name) of the indices of the
detectors in which the associated scoring is activated (see
Note 1)
("to detector WHAT(5)
....")
Default
= WHAT(4)
WHAT(6)
= step length in assigning indices
("in steps of WHAT(6)
")
Default
: 1.0
SDUM
: For dose equivalent (DOSE-EQ) scoring, the user can provide the
energy-dependent coefficients for the conversion of fluence to
effective dose and ambient dose equivalent for neutrons, protons,
charged pions, muons, photons and electrons [Roe06,Pel00].
The following dose conversion coefficients sets are available:
1) Effective dose sets from ICRP116 with a few higher energy
points extrapolted from Pelliccioni data [Pel00]
(a) EAP116 : Anterior-Posterior irradiation geometry
(b) EPA116 : Posterior-anterior irradiation geometry
(c) EIS116 : Isotropic irradiation geometry
2) Ambient dose from ICRU95 with a few higher energy points
extrapolated from Pelliccioni effective dose data
(a) AMBDS
3) Effective dose sets from ICRP74 and Pelliccioni data
[Pel00] calculated with ICRP radiation weighting factors Wr
(a) EAP74 : Anterior-Posterior irradiation
(b) ERT74 : Rotational irradiation geometry
(c) EWT74 : WORST possible geometry for the irradiation
4) Effective dose sets from ICRP74 and Pelliccioni data
calculated with the Pelliccioni radiation weighting
factors Wr
(a) EAPMP : Anterior-Posterior irradiation
(b) ERTMP : Rotational irradiation geometry
(c) EWTMP : WORST possible geometry for the irradiation
5) Ambient dose equivalent from ICRP74 and Pelliccioni data
(a) AMB74
Default
: AMBDS
Default
(DOSE-EQ scoring and option AUXSCORE not given): AMBDS
Notes:
1) USRBIN/EVENTBIN detectors are counted together, and so are USRTRACK
and USRCOLL.
2) Conversion coefficients for Effective Dose "WORST" irradiation
geometry are obtained choosing at each energy the largest value of
the coefficients for the other geometries. Note that starting with
ICRU95, the new operational quantity Ambient Dose is precisely
defined as the Effective Dose for the worst possible irradiation
geometry among those listed in ICRP116.
3) For photons and electrons, only the sets AMDS, EAP116, EPA116,
EIS116, EAP74, ERT74, EWT74, and AMB74 are implemented.
If sets from the group (EAPMP, ERTMP, EWTMP) are requested, the
corresponding set among (EAP74, ERT74, EWT74) will be used instead.
4) Dose conversion coefficients exist only for some particle types:
protons, neutrons, muons, photons, electrons/positrons, and charged
pions. 4-He conversion coefficients are also available for AMBDS,
EAP116, EPA116, EIS116. For elementary hadrons a tentative, albeit
approximate, association is made with one of the proton, neutron,
charged pion conversion coefficient set. For all other particle
types, in the past zero factor was returned. Starting with
FLUKA2023, a very crude attempt is made to return a non-zero
conversion coefficient, rescaling from available ones. This is
anyway highly inaccurate, and therefore it should never be relied
upon, particularly when heavy ions are an important contributor
to the scored quantity (see Note 5).
5) For particles such as heavy ions, for which fluence conversion
factors are not available, it is possible to score with USRBIN the
generalised particle DOSEQLET, i.e. dose equivalent as defined by
ICRU: H = D x Q(L), where L is the unrestricted Linear Energy
Transfer in water.
6) A USRBIN/EVENTBIN detector can be associated to AUXSCORE only if the
binned quantity is scored along a step (10.0 <= WHAT(1)
<= 18.0), or
if the binned quantity is activity.
