April 2024: Irradiation Panel form Education and Training Working Group

The Irradiation Panel has for many years had the delivery of educational content in support of career development as one of its key objectives.  To further this objective it announces the creation of a new ‘Education and Training Working Group’ to be Chaired by Emily Rodgers.  This group has already started work on the development of on-line training content as proposed at the two Panel meetings held in 2023.  Panel members are invited to contact Emily via ( to get involved with this new working group.  The first task of the new working group is the development of a charter for the on-line training project.  The formation and aims of the new working group will be presented and discussed at the forthcoming AGM on April 24 in London, along with a progress report on the on-line training project.

August 2016: iia and the Panel meet

The Panel and the International Irradiation Associate (iia) recently met to discuss areas of potential cooperation under the Affiliate Agreement signed in January this year.  It is recognised that while both organisations work to promote best practice in radiation processing they wish to remain independent and have different areas of strength.  The Panel has productive Working Groups, a strong role in developing, reforming and implementing standards and holds regular member meetings.  The iia has international reach, effective communication with the irradiation industries and has forged relationships with multiple regulatory, regional and industry specific organisations.  It has been agreed that the iia will assist the Panel with promotion of its activities to the wider irradiation community including publication of the output from Panel Working Groups on the iia website.  A representative of the iia will attend future Panel meetings to provide an update on current iia activities and to be available to discuss and learn more of relevant industry issues.  There is also a desire from both sides to develop joint activities and to arrange joint meetings to address wider industry issues where working together can maximise impact.

There were also sessions on process definition, validation and control which relate to the standard ISO 11137. The training involved hands-on practical sessions as well as theory. I particularly enjoyed the practical session on calibration and the stimulating exchange with other participants.  I would recommend this course to anyone who needs to learn more about dosimetry in radiation processing'.
