5. RP Handbook Chapter 1 Outlines
The legal framework for radiation protection
The responsibilities with reference to
ESS Top level description (ESS )
Functional description of Radiation Protection Group (ESS )
Basic principles of radiation protection
with reference to General Safety Objectives (ESS )
Compliance
Quality

6. Functional description Radiation Protection Group
ESS Document “Functional description for the Radiation Protection Group” (ESS )
The Radiation Protection Group provides expertise and services in radiation protection
Is in charge of the Radiation Protection Handbook, which outlines the regulatory frame work for matters of radiation protection
Protecting people on the ESS site and the public from ionising radiation hazards linked to ESS activities.

7. RP Handbook Chapter 2
Outlines the General Radiation Protection Rules, in particular
Dose limits and Dose Restrictions
Categorisation of workers and radiological areas
Radiography
Barriers and signs
The current GSO is followed and it states in
Non-designated area
1. In non-designated areas, air and surface contamination may not occur in addition
to natural background activity.
2. At permanent workplaces, the annual effective dose should not exceed 50 mSv.
3. At non-permanent workplaces, the dose rate shall not exceed 0.5 mSv/h.

8. RP Handbook Chapter 2
The chapter points to other ESS approved documents, e.g.
ESS General Safety Objectives (ESS )
ESS Rules for Radiation Work Permit and implementation of ALARA in operation (ESS )
ESS Instruction for Radiography on site (ESS )
Definition of Supervised and Controlled Radiation Areas (ESS )
ESS Rules for Medical Examination (ESS )

9. RP Handbook Chapter 4 Outlines work with ionising radiation
Main content for current operations are:
Planning
Risk Assessments and Readiness Review for Safety
Posting
Documentation and archiving
Reporting of events

10. RP Handbook Chapter 4 Outlines work with ionising radiation
Including for designated areas (such as the Test Stand) :
Controls
Local Rules
Protective Equipment in designated areas
Access requirements and controls

11. Ion source and LEBT beam commissioning
Ion source and LEBT beam commissioning – currently on-going applying ESS operational limits and conditions.
Limits:
Personnel is NOT categorised as exposed workers (less than 1 mSv/year).
Beam commissioning shall not exceed proton beam energy of 80 keV.
Systems important to safety:
A safety fence containing 2 mm lead shielding around the entire ion source with a height of 2.5 m.
A Personnel Safety System 0 (PSS0), that controls the access to the area inside the fence (PSS0 controlled area).
Passive environmental dosimeters around the safety fence, for monitoring radiation levels outside the fence.

12. RP Handbook Chapter 5 & 7
Chapters 5 and 7 are in particular addressed to work carried out by Radiation Protection staff, e.g. Ch 5. Radioactive materials Sealed sources for functionality test of radiation detectors Ch 7. Radation monitoring Area monitoring by passive measurement technique (OSL) Hand held RP instruments (operated by RPO)

13. RP Handbook Chapter 5 Outlines
Requirements for sealed radioactive sources
Inventory of radioactive sealed sources
Requirements for source storage
Control of radioactive sources
Handling and Use of Sealed Radioactive Sources
Training in Handling
Transportation
Event reporting

14. RP Handbook Chapter 7 Outlines Radiation monitoring
Which kind of RP monitors are in use
Hand-held monitors
Passive radiation monitoring
Calibration of radiation monitors
Maintenance and Operations
Archiving Radiological Monitoring Data
Present scope: Radiation zoning validation of non-designated areas and supervised radiation areas.
