Surface Sterilization - Using Low Energy Electron Beam

For a long time, dosimetry has needed an intelligent, turnkey system -- a system that eliminates unwanted variability, insures absolute dose traceability, and conforms to all national and international standards. Precise dose measurement is the only way you can assure managers, customers and regulatory authorities that you’ve achieved consistent, verifiable dose delivery. GEX is the answer.

GEX Understands the Special Needs of Surface Sterilization Dosimetry

Low energy electron accelerators with low penetration voltages (<kV) are now being effectively applied to sterilize product and packaging surfaces in accordance with the ISO 11137 radiation sterilization guidance document. The dosimetry requirements for low energy electron applications such as this are more complex than dosimetry performed using higher voltages or highly penetrating radioisotopes such as 60Co or 137Cs.

GEX has been participating in the development of low energy electron beam dosimetry solutions that now provide the means of fully satisfying the ISO 11137 dosimetry guidance requirements.

A Total Dosimetry Solution for Surface Sterilization with Low Energy Electrons

GEX offers a fully-automated, easy-to-use routine dosimetry system developed specifically to meet the needs of the surface sterilization industry. Our products are tested and proven, with over 20 years experience working directly with sterilization customers.

Our highly-accurate dosimetry system makes easy work of the stringent requirements of ISO 11137, dosimetry requirements for the IQ, OQ and PQ dose mapping and routine process monitoring requirements.

We provide a complete dosimetry system, so meeting all requirements is simple and straightforward. GEX’s WINdose System includes:

instrumentation and its references
dosimeters
a full set of dosimetry procedures

The WINdose System – Features and Benefits

What are the features and benefits of the GEX’s WINdose Dosimetry System for gamma sterilization?

FEATURES	BENEFITS
Flexible, low-profile, nominal 18 micron thick radiochromic film dosimeters	Allows dosimeter placement on, in and around dose measurements for dose mapping products and packaging with minimal impact on the measurement outcomes
Peel open chevron dosimeter pouches with a clear see-through window	Eliminates needs for sharp tools needed to open the dosimeter pouches while providing a means to verify the presence and position of the dosimeter inside
Individual radiochromic film dosimeters are mounted on unique barcoded paper handles	Eliminates dosimeter handling damage or contamination and speeds the dose measurement process while providing a means to track dosimeters from placement and retrieval through final measurement. Individual barcoded dosimeters are a means of assuring absolute dose traceability with the added ability to identify and re-measure individual dosimeters for quality investigational purposes
Wide long-term storage temperature range	Store at ambient temperatures between 15 °C and 30 °C for optimum results
Pre-irradiation stable	Dosimeter batch shelf-life greater than 10 years
Stable irradiation response function	Calibration response function demonstrated stable up to 10 years
Wide irradiation process dose range (<1.0 to > 120 kGy)	Single dosimetry system that can be used to measure the wide range of doses required for ISO 11137 minimum sterilization dose setting (1.5 kGy to 18 kGy); maximum product and packaging performance dose setting up to 150 kGy; routine product dose mapping and process monitoring 6.0 kGy to 60 kGy
Wide irradiation temperature range (-195 °C to +60 °C)	Dosimeters can be calibrated and used for special low temperature processing with liquid nitrogen, dry ice, or ice or under normal ambient temperature irradiation processing
Post irradiation heat treated B3 dosimeters remain stable for one year or more	The post irradiation stability of B3 dosimeters eliminates the post irradiation time control requirements associated with other dosimeters and allowing reliable post irradiation measurement investigation as well as their use as references in an instrument checks program to verify measurement instrument stability
Standardized design controlled dosimetry system measurement software program	The fully integrated, pre-validated WINdose Dosimetry System gamma version provides an automated dosimetry solution that is, easy to install and simple to use for generating fast, accurate and highly reproducible dose measurement reports
High accuracy predictable doses that are highly reproducible	B3 WINdose Dosimetry System enjoy the highest accuracy dosimetry attainable in a routine dosimetry system as measured in terms of lower overall combined uncertainty
Continuing dosimetry improvement program	The large installed base of B3 WINdose Dosimetry System users provides an ongoing source of feedback used to support our continuous improvement efforts

Why Choose the WINdose Dosimetry System?

Our popular WINdose Dosimetry System is ideally suited for the majority of dose measurement applications between 1.0 and 150 kGy. Approximately 85% of all dosimetry systems installed worldwide since 2004 are GEX systems. Fast and easy, the B3 WINdose is the most accurate dosimetry system available on the market today.

No other dosimetry system at any price can match the speed, pre- and post- irradiation measurement stability, and accuracy of our B3 WINdose Dosimetry System for dose requirements from 1.0 to 150 kGy.
No other system can provide the absolute dose measurement traceability of our B3 dosimeters. Each packaged dosimeter is barcoded with a matching ID number to the dosimeters inside. Each dosimeter replicate inside the package is imprinted with a unique dosimeter ID.
The B3 WINdose Dosimetry System is supplied with a full set of standard operating procedures and supported with a series of Technical Memos to support installation, calibration and use of the dosimetry system.
GEX offers complete dosimeter calibration services and the related products so there is no need to do it yourself or find another provider. As part of our total dosimetry solution, this key element provides the user with a single resource for dose traceability and calibration needs. Working hand-in-hand with our customers enhances our ability to meet each customer’s individual needs.
Our unbeatable customer service – no one else offers a total dosimetry solution!
