10th International Workshop on Radiation Processing

(In-person only event)

Date: February 5, 2024 - February 9, 2024

Event Location: The Westin San Diego Bayview, San Diego, California, United States

Organized by: ASTM Committee E61 on Radiation Processing



About the Event

The 10th International Workshop on Radiation Processing will be held February 5, 2024 - February 9, 2024. The workshop is organized by ASTM Committee E61 on Radiation Processing, and will be held in at The Westin San Diego Bayview in San Diego, California, United States in conjunction with the standards development meetings of the committee. The language of the workshop will be English.

The workshop follows the very successful nine previous workshops given in North America and Europe. The tenth workshop continues to evolve in order to provide the most value to those attending. Attendees will get an end-to-end view of radiation processing, including dosimetric aspects. In keeping with the previous workshops, this workshop will focus on practical examples and case studies, highlighting the way in which ASTM documents can be utilized to meet the requirements in the ISO radiation standards.

This workshop will provide a combination of plenary presentations, hands-on practical exercises, informal "roundtable" sessions, and case studies. Please register early.

Attendance will be limited to the first 50 participants who register.


Objective and Scope

Standards published by ASTM International’s Committee E61, many of which are also recognized in the ISO 11137 series of standards, will form the basis for the discussions and hands-on exercises. In addition, the workshop will cover broader aspects of radiation processing such as microbiology and dose establishment, setting process specifications, process capability assessment and change control challenges. Sessions will include the more traditional topics of dosimetry selection, calibration, dose mapping and process control. Attendees will use hands-on activities to reinforce the standard practices identified in ASTM standards.

The objective is to improve the attendee’s knowledge and understanding of radiation processing to facilitate high quality decision making during routine application.

The workshop's major topics will include:

  • Radiation Physics & Statistics
  • Microbiology & Establish Dose Requirements
  • Dosimetry Calibration, Uncertainty & Application
  • Operational Qualification & Performance Qualification
  • Process Capability assessment (Cpk), Establishment & Control
  • Proactive Change Control
  • Gamma, X-ray and Electron Beam Change Control
  • ASTM EtO Update


Who Should Attend

The industry-need to improve technical competence in radiation processing and this workshop is intended for those individuals involved with their organization’s radiation processes. This would include individuals who are irradiator operators, validation personal, dosimeter and dosimetry-service suppliers, healthcare products manufacturers, sterilization service providers, food processors, quality and regulatory personnel, inspectors. Attendees will have the opportunity to interact with their peers and leaders in the radiation-processing field. The workshop format is designed to provide maximum interaction between participants resulting in mutual benefits for all.


Abstract Submission

To participate in the symposium, authors must submit a 250 to 300-word preliminary abstract using the online Abstract Submission Portal no later than DATE. To ensure your abstract was received into the ASTM database, please email symposia@astm.org and let us know that you have submitted an abstract.

The abstract must include a clear definition of the objective and approach of the work discussed, pointing out material that is new, and present sufficient details regarding results. The presentation and manuscript must not be of a commercial nature nor can it have been previously published. Because a limited number of abstracts will be accepted, be sure that the abstract is complete to allow for careful assessment of the paper's suitability for this symposium. The symposium chair(s) will notify you via email by DATE of your paper’s acceptability for presentation at the symposium. If the preliminary abstract is accepted, the author will be requested to submit a final abstract a few months before the symposium. The final abstracts will be distributed in a program booklet at the symposium.


Publication Information

Symposium authors are required to submit their papers for ASTM publication in Selected Technical Papers (STP), an online and printed, peer-reviewed publication for the international scientific and engineering community. STP papers should be full-length technical papers of approximately 10,000 words, significantly contribute to the technical literature, and must include a review of past work in the relevant area and present information of current interest or probe new fields. After the final selection of abstracts has been approved, the ASTM Editorial Office will send authors’ instructions via email, but also can be found by clicking here.

Manuscripts to be peer reviewed for the STP are due online no later than DATE at the ASTM Editorial Office. The corresponding author (the author who is the main contact with ASTM Headquarters) will receive a copy of his/her paper in portable document format (PDF). All published authors will have the opportunity to purchase reprints of their papers at a nominal cost. Only those papers submitted by the manuscript due date will be included in the STP. Please note that all submitted papers are subject to peer review by two independent reviewers.

The STP will be submitted to the Library of Congress with an ISBN number and will be reviewed for inclusion in the Web of Science Conference Proceedings Citation Index (CPCI) and Google Scholar.
