Gamma irradiation and dosimetry services


ANSTO Radiation Technology operates a range of cobalt-60 gamma irradiators for small scale irradiation of a wide range of products, and to various doses. 
 


Forms and terms of business

 

ANSTO's unique gamma irradiation facilities enable it to accurately deliver high doses of radiation with a precision not achievable in industrial-scale irradiators. 
 
Applications of gamma irradiation include food irradiation (biosecurity), agriculture, horticulture, radiobiology (including animal studies), radiotherapy dosimetry, polymer modification, vaccine development, medical devices and biotechnologies. Examples include Sterile Insect Technique, medical product verification dose experiments (to ISO 11137) and frozen human tissue sterilisation.

High dose dosimetry service


ANSTO Radiation Technology manufactures and calibrates radiation dosimeters for use in monitoring doses in high dose irradiation applications. The group's dosimeter measurements are traceable to the Australian standard for absorbed dose.
 
These reference standard dosimeters can provide traceable calibrations for routine dosimeters used by any provider of gamma irradiation services worldwide.
 
The group's dosimeters can be used to calibrate any gamma radiation field from small blood irradiators to large industrial pallet or tote irradiators. Manufacturers of sterile medical products may conduct quality control checks on the dose delivered to their products in industrial irradiators.
 
Dosimeters are manufactured following international best practice for dosimetry in radiation processing (ISO 17025 and ISO/ASTM standards). The group provides a supply and measurement service. It also supplies calibrated dosimeters to customers for irradiation and, upon return, report dosimeter readings. More information on high dose dosimetry service.
