AUXSCORE

Summary

allows to associate scoring detectors of given estimator types with dose equivalent conversion factors and to filter scoring estimators according to auxiliary (generalised) particle distributions or ion isotopic ranges. ​

USRBIN, EVENTBIN (for binning of quantities scored along a step, or for activity binnings, see Note 6)

= 3.0:

USRTRACK

= 4.0:

USRCOLL

= 5.0:

Default

= 2.0:  USRBIN, EVENTBIN

WHAT(2) =

particle (or particle family) to be considered as a filter for the associated scoring card

> -100:

particle or particle family code

≤ -100:
Isotope coding (to filter ions)​. To select atomic number \(Z\), mass number \(A\) and isomeric state \(M\):
WHAT(2) =\(-(Z\times 100 + A\times 100000 + M\times 100000000)\).
\(Z = 0\) 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–PART  (all particles)

WHAT(3) :

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

= \({\texttt{i}}_0 + {\texttt{i}}_1 \times {\texttt{100}}\)

\({\texttt{i}}_0 = {\texttt{0}}\) : ignored

\({\texttt{i}}_0 \geq {\texttt{1}}\) : the delta parent is used for filtering

\({\texttt{i}}_0 \leq {\texttt{-1}}\) : reset to default (=0)

\({\texttt{i}}_1 = {\texttt{0}}\) : ignored

\({\texttt{i}}_1 = {\texttt{1}}\) charged products of low energy neutron pointwise interactions are excluded from the application of conversion coefficients (default)

\({\texttt{i}}_1 = {\texttt{2}}\) charged products of low energy neutron pointwise interactions are included in the application of conversion coefficients

\({\texttt{i}}_1 \leq {\texttt{-1}}\) : 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(3)``…”)
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(4)``…”)
Default

= WHAT(4)

WHAT(6) =
step length in assigning indices
(“…in steps of ``WHAT(4)`` ”)
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 [Pel00],[Roe06]

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]

    1. EAP116 : Anterior-Posterior irradiation geometry

    2. EPA116 : Posterior-anterior irradiation geometry

    3. EIS116 : Isotropic irradiation geometry

  2. Ambient dose from ICRU95 with a few higher energy points extrapolated from Pelliccioni effective dose data

    1. AMBDS

  3. Effective dose sets from ICRP74 and Pelliccioni data [Pel00] calculated with ICRP radiation weighting factors Wr

    1. EAP74 : Anterior-Posterior irradiation

    2. ERT74 : Rotational irradiation geometry

    3. EWT74 : WORST possible geometry for the irradiation

  4. Effective dose sets from ICRP74 and Pelliccioni data calculated with the Pelliccioni radiation weighting factors Wr

    1. EAPMP : Anterior-Posterior irradiation

    2. ERTMP : Rotational irradiation geometry

    3. EWTMP : WORST possible geometry for the irradiation

  5. Ambient dose equivalent from ICRP74 and Pelliccioni data

    1. 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 AMBDS, 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. For heavy ions with \(Z=3\)–28 and AMBDS, the effective-dose ISO-irradiation conversion coefficients of Sato et al. are now used; higher \(Z\) uses an extrapolation. For other heavy-ion quantities a very crude rescaling of available conversion coefficients is used. The latter 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: \(H = D \times Q(L)\), 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.

  7. The old “GRS” Ambient dose equivalent conversion factors had been deprecated and are no longer available.
