DATA MANAGEMENT AND TOOLS FOR THE ACCESS TO THE RADIOLOGICAL AREAS AT CERN

As part of the refurbishment of the PS accelerator complex Personnel Protection System, the Radiation Protection (RP) checkpoints and buffer zones, for the radiological controls of equipment removed from the beam areas, have been incorporated into the design of the new access points. Integration of the RP and access control equipment has been very challenging due to lack of space in many of the zones, and it provides an integrated access concept to the primary beam areas. Although successfully carried out, our experience from the commissioning of the first installed access points shows that the integration should also include the software tools and procedures. This paper presents an inventory of all the tools and data bases currently used (*) in order to ensure access to the CERN radiological areas according to CERN’s safety and radioprotection procedures. We summarize the problems and limitations of each tool as well as the whole access process, and propose a number of improvements for the different kinds of users. The aim is to optimize the access process and the operation & maintenance of the related tools by rationalizing and better integrating them.
