TS ISO 12749-2

TS ISO 12749-2 is a vocabulary standard that gathers terms and definitions for radiological protection within the field of nuclear energy, nuclear technologies, and related nuclear applications. Its purpose is to clarify technical language and help different organizations and disciplines use the same concepts with the same meaning.

Why radiological protection terminology matters

Radiological protection deals with managing the effects of ionizing radiation on people, the environment, and equipment. In this field, concepts such as dose, exposure, contamination, shielding, monitoring, and control are closely linked. Consistent definitions are essential for technical communication, training, operational procedures, and cooperation across organizations. This standard brings together terminology for those concepts in a way that supports common understanding.

What this part covers

According to the supplied scope, the document defines terms and definitions related to radiological protection concepts in the context of nuclear energy, nuclear technology, and various nuclear applications. In other words, its focus is not on design rules, test methods, or performance limits; it is on the language used to describe the subject. That makes it useful where the same radiological protection concepts must be understood consistently across power generation, research, medicine, industry, and other radiation-related settings.

• It is a terms-and-definitions document, standardizing technical vocabulary.
• It covers radiological protection language linked to nuclear energy and different nuclear applications.
• It is intended to support common understanding and clearer communication.
• It is presented as the TSE edition based on ISO 12749-2:2022.
