Dose visibility
Fernando B. S. Pedrosa on behalf of John Pedersen, Thomas Otto, CERN RP Group and IMPACT Safety sub-working groupSlide2
The IMPACT DIMR form was defined in the initial specifications of IMPACT by the IMPACT safety sub-working group based on the existing DIMR form (RP) , and implement
ed
in the first version of IMPACT
IMPACT and the DIMR
Slide from Katy
Foraz on the initial specifications of IMPACT in October 2011Slide3
It is possible to create an individual DIMR per activity;
IMPACT and the DIMR
The DIMR part in your IMPACT activity request, is where today you can see your own operational dose
DIMR part sent for approval using the EDH approval processSlide4
It is possible to create a DIMR per activity as part of a Work Package DIMR
IMPACT and the DIMR
DIMR part sent for approval using the EDH approval process
The DIMR part in your IMPACT activity request, is where today you can see your own operational dose
Advantages when compared with a big individual DIMR:
The responsibility of optimization stays as well with the sub-DIMR responsible (=activity responsible) and not only with the Work Package DIMR responsible (=activity cluster responsible);
If the same work has to be done in the future, but not all the activities are needed, then it is easier to remove an activity.Slide5
Dose data in IMPACT
The link between the operational and personal
dosimetry
databases of RP and IMPACT exists since the implementation of the new operational reading system.The new operational dose reading system uses the IMPACT activity ID as the condition to start the operational dosimeter, and to associate a dose to an activity.
The dose values are updated as follows:
Operational dose per activity – Daily (one value per activity and per day);31 days and 12 months operational dose history – Daily (independent of the activity);31 days and 12 months personal dose history – Daily (but if the person didn’t read the personal dosimeter in the last month, then there will be no data for the 31
days history).Slide6
Dose Visibility in IMPACT
Why do we need it in IMPACT?
To centralize in a single place all the information linked to an activity;
To allow a daily follow-up, by the different people concerned, on the dose taken by the participants per activity;
To make the monitoring process less time consuming and more direct;Slide7
Dose Visibility in IMPACT
Why do we need a clear definition of who can see the different doses of a person?
The dose data of a person is considered confidential data
Example:
“…
en France, seuls l’expert en radioprotection ou la PCR et le médecin du travail
ont
accès
aux doses nominatives
efficaces
/passives des
intervenants. Le responsable de chantier et/ou le
superviseur
ont
accès
uniquement
aux doses
opérationnelles
prises
sur
le
chantier.”

Other restrictions
RP is responsible to ensure that CERN’s dose objective is respected for any given person for a worksite in the light of their dose history. The PCRs defines the dose limits of the contractors in compliance with CERN’s dose objective. (
Each DH, GL, PCR, etc. has the right to set even lower dose objectives for his team)
The activity responsible needs to make sure that the dose received by a person X for a given worksite does not exceed the objective defined.
In no case can anybody else than the competent PCR determine which contractor personnel can work on a given worksite.Slide9
Dose Visibility document
The dose visibility in IMPACT is defined in the EDMS document 1313535;
The following people will have dose visibility rights in IMPACT:
Experiment Level:
(LHC) GLIMOS;
Deputy (LHC) GLIMOS;(LHC) Experimental RSO(LHC) Deputy experimental RSO;
RPE.
Department Level:
Department Head;
Deputy Department Head
DSO;
Deputy DSO;
RSO;
Deputy RSO.
Group Level:
Group Leader;
Deputy Group Leader
RSSO.
Section Level:
Section Leader;
Contractor:
PCR;
Deputy PCR.
Activity cluster responsible;
Activity responsible;
CERN RP group;
Activity participant.Slide10
Difference
The differences between the document three weeks ago and the present one are:
Experiment Level:
(LHC) GLIMOS;
Deputy (LHC) GLIMOS;
(LHC) Experimental RSO(LHC) Deputy experimental RSO;RPE.
Department Level:
Department Head;
Deputy Department Head
DSO;
Deputy DSO;
RSO;
Deputy RSO.
Group Level:
Group Leader;
Deputy Group Leader
RSSO.
Section Level:
Section Leader;
Contractor:
PCR;
Deputy PCR.
Activity cluster responsible;
Activity responsible;
(deputy)
CERN RP group;
Activity participant.
Note:
The hierarchy line of a worker has already access to the personal dose data via HRT.Slide11
Dose Visibility rightsSlide12
To be done
Create the “PCR”, “CERN RP Group” and “Activity Cluster” roles in the AIS roles;
Assign the correct responsible to update each role as defined in the document.
Some support from the departments maybe needed to get this on the priority list
Implement it in IMPACTSlide13
Thank you very much for your attention!
