Abstract:
Dose conversion coefficients connect radiation field quantities with the protection quantities and operational quantities. In radiation protection practice, it plays an important role in facilitating the conversion between various measurement values, enabling compliance with individual dose limits, and optimizing radiation protection strategies. During the conversion process, conversion coefficients are affected by the types of rays, irradiation geometries, and human tissues and organs. Notably, the continuous development of anthropomorphic digital phantoms has led to the constant updating of conversion coefficients and the broadening of their application fields. However, with the development of radiation protection theory, new challenges have emerged in the establishment of conversion coefficients. This paper provides a concise overview of these aspects, aiming to give readers a basic understanding of the significance, application, and challenges associated with the conversion coefficients. Such an understanding will facilitate the effective implementation of the newly released standard WS/T 830.
