9. RADIOLOGICAL PROTECTION STAKES
Drivers and people working in the dispatching room are the most exposed,
the maximum doses are approaching the legal limit
Effort has to be made in order to reduce their doses.

14. difficulties to point out doses due to CBI
DRIVERS (2)
Company N°1
maximum individual dose once registered 36 mSv (2000) and a collective dose around 45 mSv
difficulties to point out doses due to CBI
Measures had to be taken
24/10/2002

15. MEASURES TAKEN (1) ELUMATIC
Estimated collective dose reduction for the company N°1: 9,4 mSv (- 20%)
57,5€ invested (additional tray for the printer)to avoid 1 mSv.
Dose reduction cannot be estimated for the person working at the production chain
24/10/2002

16. MEASURES TAKEN (2)
PRP
Estimated collective dose reduction for the company N°1: 10 mSv (- 20%)
83 € invested (additional printer and 10 half carts ) to avoid 1 mSv.
Dose reduction cannot be estimated for the person working at the production chain
24/10/2002

17. Avoid bad posture leading to back injury
MEASURES TAKEN (3)
Estimated collective dose reduction for the company N°1: None
7600 € invested
NOT REASONABLE ?
Avoid bad posture leading to back injury

18. Identification and description of tasks,
PENDING ACTIONS (1)
Identification and description of tasks,
links between tasks and function,
dosimetric analysis,
proposition of options leading to dose reduction
sensibility and cost analysis,
The first objective is the know precisely when and how doses are received and by whom.
The second objective is to provide dose reduction options related to the whole process (from order to delivery)

19. PENDING ACTIONS (2)
Source exposure contribution analysis ……  by the end of this year.
