Advancements in radiation research and safety protocols are critical in diverse fields, from space exploration to medical applications. In a recent webinar, two eminent experts in radiation physics shared their insights on cutting-edge topics: space radiation and the revision of radiation dosimetry standards.
Astronauts’ Exposure to Space Radiation: Health Risks and Countermeasures
Prof. Francesca Ballarini, a distinguished professor of medical physics at the University of Pavia and past president of the Italian Society for Radiation Research, delivered an insightful presentation titled “Astronauts’ exposure to space radiation: health risks and possible countermeasures.” Space radiation is a major concern for human spaceflight, particularly in long-duration missions. Astronauts are exposed to higher levels of cosmic rays and solar radiation, which pose significant health risks, including increased cancer risk, central nervous system effects, and damage to the cardiovascular system. Prof. Ballarini emphasized the importance of developing effective countermeasures, such as shielding technologies and personalized risk assessments based on genetic susceptibility. These countermeasures are crucial to ensuring the safety of astronauts as humanity ventures further into deep space.
Updates on Radiation Dosimetry: The Revision of IAEA TRS398
The second presentation, delivered by Prof. Retano Padovani, the coordinator of the Master’s of Advanced Studies in Medical Physics at ICTP, was titled “News in the revision of the IAEA TRS398.” The IAEA TRS398 is an international protocol used to ensure accuracy in radiation dosimetry, which is vital for consistent and safe radiation treatments in medicine. Prof. Padovani provided an overview of the ongoing updates to this protocol, which reflect advancements in radiation measurement technologies and clinical practices. The revision aims to improve dosimetry accuracy for modern radiotherapy techniques and ensure worldwide consistency in patient treatment outcomes. These updates are essential to adapting the protocol to the evolving needs of radiation therapy.
