ICRPAEDIA: The System of Radiological Protection: An Overview


The System of Radiological Protection contributes to an appropriate level of protection from harmful effects of ionising radiation. Protection objectives are defined for both people and the environment.

Protection is based on three fundamental principles related to: doing more good than harm (the justification principle), keeping doses as low as reasonably achievable (the optimisation principle), and ensuring no person receives an unacceptably high dose (the limitation principle).

These principles are universal, but various exposure categories and situations are defined to help apply them most effectively in different circumstances.

The System of Radiological Protection is based on scientific knowledge, ethical values, and more than a century of practical experience.

It forms the basis of standards, regulations, guidance, programmes, and practice, worldwide.
