TS ISO 12749-2

TS ISO 12749-2 is a vocabulary standard that brings together terms and definitions for radiological protection within the field of nuclear energy and nuclear technologies. It is intended to support a common technical language so that the same concepts are used consistently across engineering, operations, regulation, and documentation.

Why radiological protection terminology matters

Radiological protection is the technical discipline concerned with understanding, limiting, and controlling the effects of ionizing radiation on people and the environment. In nuclear applications, that discipline involves concepts such as exposure, dose, protection principles, monitoring, and control. A vocabulary standard does not prescribe design rules or test procedures; its value lies in aligning the meaning of terms so that different organisations interpret them in the same way.

What this part covers

Based on the supplied scope, this part of ISO 12749 lists clear and unambiguous terms and definitions related to radiological protection concepts in the nuclear field. Its purpose is to facilitate communication and promote common understanding. It therefore serves as a terminology reference rather than a performance standard or method standard.

• Covers radiological protection terminology used in nuclear-energy contexts.
• Supports consistent use of definitions across technical documents.
• Helps reduce ambiguity in professional communication.
• Focuses on vocabulary alignment rather than operational requirements.

In radiological protection work, precise wording matters because terms such as dose, exposure, contamination, shielding, monitoring, and field control can affect how documents are read and applied. This standard helps organise that language at the vocabulary level, which is especially useful in safety documentation, training, operating procedures, and technical reporting.
