What is X-ray Irradiation Processing?
The X-ray irradiation process utilizes photon radiation for a variety of applications, including sterilization, decontamination and materials modification. The X-ray process is compatible with most materials and provides excellent penetration on dense products.
What is X-ray Irradiation?
X-ray starts as an electron beam where electrons are generated and accelerated to gain energy.
Electrons are generated in equipment with an energy of 5 to 7.5 MeV (million electron volts) and at a high power in the hundreds of kW (kilowatts).
The electrons are then focused on a specific metal target of high atomic number.
The X-ray radiation is generated through a process called Bremsstrahlung to create electromagnetic energy (photons) with an energy in the same range as gamma.

What are the Benefits of X-ray Irradiation Processing?
X-ray irradiation is safe, reliable and highly effective at treating a wide variety of products with varying densities.
The combination of shorter exposure time and improved Dose Uniformity Ratio (DUR) make X-ray irradiation a viable processing option for a variety of products.
Similar to electron beam, X-ray processing is powered by electricity. Benefits of X-ray include:
- Improved penetration ability of photon energy, similar to gamma
- Fast and efficient targeted processing that facilitates scale from carton to full pallets of product
- Flexibility – ability to mix different products with different dose requirements in the same irradiation cycle
- Reduced material degradation with reduced processing times and reduce of the maximal dose given to product in comparison to Gamma and E-beam irradiation.
- Ability to process to tight dose specifications through improved DUR
- Incremental lap-based dose delivery, offering flexible and precise process definition across a wide range of doses
Standards for X-ray Irradiation:
X-ray steriization is supported by the internationally recognized consensus standard, ISO 11137, which describes the approach to validating a dose to achieve a defined sterility assurance level (SAL).
X-ray Irradiation Support Services:
In addition to irradiation sterilization, STERIS AST provides our Customers with laboratory testing and technical support solutions at every stage of the sterilization design process, from product development through routine processing.
Our Radiation TechTeamTM guides Customers through the irradiation validation process, provides solutions for unique project needs, and supports routine processing through periodic dose audits.
Our Radiation Technology Centers (RTCs) support our Customers with radiation test activities such as product trials, dose establishment and dose verification.
The RTCs provide high-precision dose delivery for validation, dose mapping, dose audit, and research purposes.
Our laboratory testing services provide Customers with:
- Radiation validation support
- Microbiological testing, including bioburden testing, test of sterility, microbial identification and more
- Bacterial endotoxin testing
- Product and packaging testing, including accelerated & real-time aging, transportation/distribution testing, sterile barrier integrity and more
As part of our complete radiation validation program, we will develop a protocol, assemble all testing and validation data, summarize results and make recommendations based on your product, as well as provide ongoing support through a dedicated Radiation TechTeam Project Manager.
