The 22nd International Solid State Dosimetry Conference (SSD22) will be organized by Dr. Željka Knežević and Dr. Marija Majer from the Ruder Boskovic Institute Laboratory for Radiation Chemistry and Dosimetry, Zagreb, Croatia, and it will take place in 2028. The conference will be preceeded by the Marco Moscovitch School. Exact dates and locations will be defined soon.

The inaugural Summer School, conceived by Prof. Marko Moscovitch and having Prof. Moscovitch and Prof. Stephen W. S. McKeever as “co-Deans”, was held in conjunction with the SSD21 Conference in Athens in 2001. Since then, it has been a tradition to conduct this school prior to each SSD Conference under the supervision of the International Solid State Dosimetry Organization (ISSDO). During the SSD17 in Brazil (2013), it was proposed to rename the school the Marko Moscovitch School in honor of Professor Marko Moscovitch.

​Professor Marko Moscovitch (December 30, 1953 – January 30, 2013) was a distinguished physicist renowned for his expertise in radiation detection and measurements. Born in Romania, he immigrated to Israel during his youth, serving in the Israeli Defense Forces before pursuing higher education. He later moved to the United States, where he became a professor in the Department of Radiation Medicine at Georgetown University Medical Center. There, he chaired the graduate program in health physics and radiation protection from 1990 until his passing. Professor Moscovitch’s research significantly advanced the fields of neutron radiation dosimetry, thermoluminescence, and theoretical radiation physics.

The primary objective of the Marko Moscovitch School is to impart the necessary skills and knowledge to comprehend the principles and applications of dosimetry based on solid state detectors. The curriculum encompasses foundational aspects of dosimetry, advanced applications of solid state dosimetry techniques for emergency dosimetry, dose reconstruction and dating, real-time monitoring, medical dosimetry, among other topics.

It is with great sadness that ISSDO notes the passing of Professor Helen Khoury.

Helen was one of the most important members of the Solid State Dosimetry community. She was chairperson of our organisation from 2019 to 2023 and steered ISSDO through the COVID pandemic. Helen was full professor at Federal University of Pernambuco in Recife, Brazil, and her academic and scientific contributions to the field of dosimetry, nuclear science and radiation protection have ongoing international impact.

Helen was a member of the ICRP task group 108 on Optimisation of Radiological Protection in Digital Radiography, Fluoroscopy, and CT in Medical Imaging. In 2013 Professor Khoury organised and chaired the 17th International Conference on Solid State Dosimetry in Recife and in November 2024 still organised the Reprolam Symposium in Recife for the Network for Optimization of Occupational Radiological Protection in Latin America and the Caribbean, a network that she also coordinated.

Helen was a fantastic colleague full of enthusiasm and ideas and a dedicated teacher and leader. The ISSDO community remembers her with great fondness. Professor Helen Khoury will be missed.
