This document is applicable to new projects built on new sites or within existing medical institutions, where emergency medical facilities are constructed rapidly from steel-frames and prefabricated standard plates or box structures.

This document does not include:

—    a comprehensive categorial structure for TCM;

—    a treatment procedure for TCM;

—    relevant devices;

—    terms or descriptions for subcategories of body parts, causative agents, pathological process or manifestation.

This model aims at representing the concepts applicable to Chinese materia medica processing in the making of decoction pieces.

This document is not applicable to Japanese traditional Kampo medicine.

1.2 This practice covers dosimetry for the irradiation of blood product for self-contained irradiators (free-standing irradiators) utilizing radionuclides such as 137Cs and 60Co, or X-radiation (bremsstrahlung). The absorbed dose range for blood irradiation is typically 15 Gy to 50 Gy.

1.3 The photon energy range of X-radiation used for blood irradiation is typically from 40 keV to 300 keV.

1.4 This practice also covers the use of radiation-sensitive indicators for the visual and qualitative indication that the product has been irradiated (see ISO/ASTM Guide 51539).

1.5 ISO 51939:2017 is one of a set of standards that provides recommendations for properly implementing dosimetry in radiation processing and describes a means of achieving compliance with the requirements of ISO/ASTM Practice 52628 for dosimetry performed for blood irradiation. It is intended to be read in conjunction with ISO/ASTM Practice 52628.

1.6 ISO 51939:2017 does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro-priate safety and health practices and to determine the applicability or regulatory limitations prior to use.

It is applicable to the storage of raw materials and decoction pieces used in traditional Chinese medicine.
