Radiation Protection Group (HSE-RP)
Mandate

 

The Radiation Protection Group (HSE-RP) of the HSE Unit ensures that personnel on the CERN sites and the public are protected from potentially harmful effects of ionising radiation linked to CERN activities. The DGS-RP Group fulfils its mandate in collaboration with the CERN departments owning or operating sources of ionising radiation and having the responsibility for Radiation Safety [1] of these sources.
 

The Radiation Protection Group:
 

  • assesses the hazards of ionising radiation and radioactivity from existing and future CERN installations and their associated risks for personnel and members of the public;
  • defines protective measures against radiation hazards based on the justification and optimisation (ALARA) principle;
  • monitors the implementation and the effectiveness of the protective measures;
  • authorises (suspends) the operation of an equipment, installation or activity generating ionising radiation in case of compliance (non-compliance) with CERN’s radiation protection rules;
  • develops and maintains tools, instruments and methods appropriate for the assessment of radiation hazards and risks particular to the CERN installations;
  • provides expert advice and technical support to departments and to the CERN management in all matters of radiation protection;
  • manages the conditioning, interim storage and elimination of radioactive waste;
  • is in charge of the Organisation's regulatory framework in matters of radiation protection;
  • collaborates with CERN’s Medical Service.

 

The Radiation Protection Group specifies, installs and operates on behalf of CERN:
 

  • the radiation monitoring systems for ambient dosimetry;
  • the spectrometry laboratories for operational radiation protection and radioactive waste management;
  • the personal dosimetry service to monitor individual doses of radiation workers;
  • the calibration service for radiation protection instruments to ensure the metrological traceability of measurements;
  • the pre-conditioning facility for radioactive waste and interim storage facility for radioactive waste.

Group Radiation Protection (DGS-RP)
Definitions

 

In the context of Safety policy at CERN, the terms ”Radiation Safety” and “Radiation Protection” are defined as follows:

 

CERN’s Director-General always retains overall responsibility for the Safety of all installations and operations (SAPOCO 42, paragraph 4.7). The specific responsibilities concerning "Radiation Safety" and "Radiation Protection" are delegated as follows:

 

  • Radiation Safety is the responsibility of every CERN Department owning radiation sources or using radiation sources put at its disposition. These Departments are in charge of implementing the requirements laid down in CERN’s Safety rules and documents or specified by DGS-RP in order to ensure the safe operation of their existing and future installations (accelerators, beams, experiments). The Departments are also in charge of training their personnel in matters of Radiation Protection according to the rules specified by DGS-RP.
  • Radiation Protection is the responsibility of the Radiation Protection Group of the Occupational Health & Safety and Environmental Protection UnitThe duties of CERN’s Radiation Protection Group include operational radiation protection which comprises assessment of radiological risks, classification of work places in radiation zones, implementation of control measures, monitoring radiation levels for different radiation areas and impact of radiation on the environment, monitoring the implementation of regulations and of specific rulings, approval of ALARA plans, control and characterization of radioactive material and waste.
