• To understand the role of the registrant or licensee in providing adequate safety; and
• How specific aspects of responsibility are delegated within authorized practices.
Objectives
IAEA 3
Responsibilities are held by:
• the registrant or licensee who holds a licence or registration;
Responsibility for Safety
• Radiation Protection Officers (RPO);• workers;• employers, in relation to occupational exposure;• suppliers;• qualified experts;• Medical physicists;• medical practitioners;• ethical review committees.
IAEA 4
Primary responsibility rests with:
• the registrant or licensee who holds the registration or licence; and
• employers of occupationally exposed workers.
Primary Responsibility for Safety
IAEA 5
Subsidiary Responsibility for Safety
Subsidiary responsibility
• The registrant or licensee may appoint other parties or people to carry out certain actions and tasks;
• However, overall responsibility for protection and safety always remains with the registrant or licensee.
IAEA 6
• develop, implement and document a protection and safety Program;
• ensure compliance with the requirements set out in the legislation and the regulations.
Responsibilities of Registrants and Licensees
Registrants and Licensees and employers shall:
• establish radiation safety objectives;
IAEA 7
• shall have sufficient resources (financial and personnel) to implement required safety requirements;
• should be verified at regular intervals to ensure that the radiation safety objectives are being achieved.
Responsibilities of Registrants and Licensees (cont)
The protection and safety Program:
• shall be subject to regular review of the measures needed to achieve radiation safety objectives;
IAEA 8
• will provide for consultation and cooperation between all relevant parties with respect to radiation safety;
• will ensure that appropriate records are maintained regarding the discharge of responsibilities.
Responsibilities of Registrants and Licensees (cont)
The protection and safety Program:
• shall identify, prevent and prompt corrective actions or any failures or shortcomings in the radiation safety measures;
IAEA 9
• radiation protection performance requirements;
Responsibilities of Registrants and Licensees (cont)
Registrants and Licensees are also responsible for:
• verification of protection and safety;
• occupational, public and medical exposure protection;
• management requirements;
• safety of sources.

Duties of the RPO
• monitoring radiation protection and safety;
The RPO’s duties include:

• ensuring that licence details and safety arrangements are updated as necessary;
Duties of the RPO (cont)
The RPO’s duties include:
• providing information and notifications to the Regulatory Body as may be required by the legislation;
• keeping the registrant or licensee informed.
IAEA 13
• appropriately use the monitoring devices, protective equipment and protective clothing provided by the employer / registrant or licensee;

• appointed to advise the registrant or licensee or the employer on the observance of regulations;
Responsibilities of Qualified Experts
Qualified experts may be:
IAEA 17

• medical practitioners are responsible for ensuring overall patient protection related to medical exposures.
Responsibilities of Medical Practitioners
Justification of medical exposures
• medical exposures shall be prescribed by a medical practitioner;
IAEA 18

Responsibilities of Medical Practitioners (cont)
Health surveillance of workers
• to ensure initial and continuous fitness of workers for their intended tasks;
IAEA 19
• the justification of screening procedures (e.g. chest screening, mammography screening);
Responsibilities of Ethical Review Committees
