For decades, the phrase « time, distance, and shielding » has been presented as summarizing the « basics » of radiation protection.
Indeed, for protection from external radiation sources, these three principles are probably the most important ones on which a worker can make decisions and take actions.
However, these principles do not address protection against intakes of radioactive materials or « ontakes » (skin contamination), other risk-limiting measures, or other important protective measures taken by governments, public health agencies, regulators, and institutional programs (measures such as performance standards, health education, facility engineering requirements, and administrative procedures).
I have identified ten principles and ten accompanying commandments of radiation protection : time, distance, dispersal, source reduction, source barrier, personal barrier, decorporation, effect mitigation, optimal technology, and limitation of other exposures.
Corresponding non-technical forms of the commandments are hurry (but don't be hasty) ; stay away from it ; disperse it and dilute it ; use as little as possible ; keep it in ; keep it out ; get it out or off of you (after intake or skin contamination) ; limit the damage ; choose the best technology (perhaps a non-radiation technology) ; and don't compound risks (don't smoke).
Technical versions of the commandments are also provided using the verbs « optimize, » « maximize, » or « minimize. » Not all commandments ...
