51939

The number is primarily associated with ISO/ASTM 51939 , an international technical standard and practice for blood irradiation dosimetry . ISO/ASTM 51939: Blood Irradiation Practice

While the ISO standard is the most comprehensive "report" linked to this number, it also appears in several other niche data reports: The number is primarily associated with ISO/ASTM 51939

: It applies to self-contained irradiators using radionuclides like Cesium-137 ($^{137} ^{60}$Co) , or X-radiation. : The most recent major revision is ISO/ASTM

: The typical absorbed dose range specified is 15 Gy to 50 Gy (Grays). : Covers installation

: The most recent major revision is ISO/ASTM 51939:2017 , which updated the format and narrowed the focus to self-contained photon irradiators, removing older teletherapy and electron beam sections. Other Notable Contexts for 51939

This standard outlines the procedures for ensuring that blood and blood components receive the correct ionizing radiation dose during treatment. It is a critical "long report" or practice guide used by the blood-banking community to prevent Transfusion-Associated Graft-Versus-Host Disease (TA-GVHD).

: Covers installation, operational, and performance qualification of irradiators, as well as routine dosimetric procedures.
