A new article, born from the collaboration between TRAD’s Software and Engineering Services, was published in the Volume 231, June 2026, 112218 of the Annals of Nuclear Energy.This article provides results for a comparison of several methods used to generate importance map and improve performances of Monte Carlo simulations. The results show a significant gain in performance for MCNP5 using variance reduction techniques and a gain even more important for the Monte Carlo code RayXpert which uses an importance map generation algorithm based on Placzek theory. This study reinforces our position on variance reduction techniques and open new perspectives for the optimization of our simulation tools. [...] Read more

Save the date and register below 👇 https://www.rayxpert.com/radiation-processing-modelling-your-accelerator-for-product-design-webinar-on-november-16th-9-am-central-us-time/ Sterilization by radiation processing is a standardized process for some health care devices. Sterility validation is part of product development and evaluation of dose distribution in products is a key step as it can impact the choices made during the design of such products (Radiation processing may present disadvantages of inducing modifications for exposed materials.).The qualification of irradiated products to assess their performance is mandatory and obviously requires prototypes in hands, which can be a (long) iterative process. In a world where time to market is essential to remain competitive, Radiation Processing Modelling is an appropriate tool to consider radiation impacts and dose distribution at an early stage of the product design and therefore improve the design efficiency of a new product.

We are very grateful to our wonderful partner for hosting us on their stand. Come and meet us on IBA’s booth to speak about RayXpert : “A modeling software to predict dose maps !” We look forward to seeing you in Bangkok! The International Meeting on Radiation Processing (IMRP) is recognised as the leading international event for those involved in the application or science of radiation processing. It is where the business and science of irradiation come together to discuss recent advances, current trends as well as the issues and opportunities that impact the commercial use of ionizing radiation. IMRP is organised every 2-3 years on a different continent by the International Irradiation Association (iia). The IMRP program is always topical and includes regional, technology and application updates from industry leaders. The meeting format has evolved for IMRP20 to enable participants to only attend a forum on their specific area of interest. The IMRP exhibition, side events and technical tours are great opportunities to learn and to meet industry colleagues. The iia understands the importance of networking and has allowed for this at IMRP20 with networking events, receptions and other opportunities to discuss the science and business of irradiation. https://www.linkedin.com/feed/update/urn:li:activity:6986589124421918720 [...] Read more

Reducing the uncertainties in modelling results through better understanding of the impact of physical uncertaintiesBy Nicolas MARY1, Cédric DOSSAT1, Ludovic EYCHENNE1, Nathalie CHATRY1 TRAD Tests and Radiation, 907 voie l’Occitane, 31670 Labège, France In the field of radiation processing, modelling is an asset. It can be used to investigate different loadout, assess the viability of a process, determine whether a double-sided irradiation will be necessary, etc… To that end, understanding where the uncertainties stem from is a critical aspect, both with measurement and with simulated results. With regard to radiation processing, both the lowest dose and the highest dose received by the target are of importance, meaning that penalizing hypothesis cannot be used so as not to skew the results toward either high or low results. Nonetheless, for practicality reasons, hypothesis often need to be used regarding parameters such as chemical composition, thickness of radiation shielding, sources’ activity, distance between source and targets, etc. Using the RayXpert® 3D Monte-Carlo software, we aim at evaluating the impact of standard uncertainty on the dose (water kerma) on a typical Co-60 irradiator. Uncertainties regarding the source activity, distance between target and source and thickness of parts of the packaging will be investigated. [...] Read more
