GSO ISO/ASTM 51939:2017 Scope
1.1 This practice outlines irradiator installation qualification,
operational qualification, performance qualification, and
routine product processing dosimetric procedures to be followed
in the irradiation of blood and blood components by the
blood-banking community. If followed, these procedures will
help to ensure that the products processed with ionizing
radiation from gamma, X-radiation (bremsstrahlung), or electron
sources receive absorbed doses within a predetermined
range.
1.2 This practice covers dosimetry for the irradiation of
blood for these types of irradiators: self-contained irradiators
(free-standing irradiators) utilizing 137Cs, 60Co or X-radiation
(bremsstrahlung), teletherapy units, and electron accelerators.
The absorbed dose range for blood irradiation is typically 15
Gy to 50 Gy. In some jurisdictions, the absorbed dose range for
blood irradiation is 25 Gy to 50 Gy.
1.3 The energy range is typically from approximately 40
keV to 5 MeV for photons, and up to 10 MeV for electrons.
1.4 This practice also covers the use of radiation-sensitive
indicators for the visual and qualitative indication that the
product has been irradiated.
1.5 This standard 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 appropriate
safety and health practices and to determine the
applicability or regulatory limitations prior to use.
