Jill Fitch, a distinguished figure in the field of radiation protection, has left an indelible mark through her exemplary career and outstanding service. We commemorate her enduring contributions. Jill embarked on her academic journey by completing her BSc at the University of Sydney in 1957, followed by a Masters in Radiation Biology and Radiation Physics at the University of London, UK, in 1963. In the early stages of her career, Jill devoted 13 years to serving as a medical physicist in hospitals across Australia, the UK, and the USA. Her wealth of experience led her back to Australia in 1977, where she assumed the pivotal role of Senior Health Physicist in the Radiation Control Section of the South Australian Health Commission. Jill's commitment to professional radiation safety societies was exemplified through her leadership roles. She served as the Chair of the SA Branch of the Australasian College of Physical Scientists and Engineers in Medicine in 1983. Subsequently, she held the position of President of the Australasian Radiation Protection Society (ARPS) from 1984 to 1986. Her international influence was evident as an Executive Council Member of the International Radiation Protection Association from 1988 to 1996. A significant chapter in Jill's career unfolded during 1984 and 1985 when she served as a Commissioner on the Royal Commission into British Nuclear Tests in Australia. Her efforts in this role played a crucial part in the effective clean-up of radioactive contamination at the Maralinga test sites. Jill's expertise extended globally, representing South Australia and Australia on various national and international committees. Notable among these were her roles on the Commonwealth’s Radiation Health Committee and Radiation Health and Safety Advisory Council, South Australia’s Radiation Protection Committee, and her involvement with the International Atomic Energy Agency (IAEA). During her tenure with the IAEA, she participated in missions to Malaysia, Brazil, Indonesia, and Thailand, making significant contributions to global radiation protection. In recognition of her outstanding public service, particularly in the field of radiation protection, Jill Fitch was awarded the Public Service Medal in the Queen’s Birthday Honours in 2003. Jill retired in February 2004 from the role of Director, Radiation Protection Division, Environment Protection Authority, leaving behind a legacy of excellence and dedication to the advancement of radiation protection.
After the war, Ray pursued studies in science at Melbourne University, laying the foundation for a career that would span decades.

Jim's journey in the realm of radiation protection has left an enduring legacy that has significantly shaped the Australian Radiation Protection Society (ARPS) and the broader field. We acknowledge and celebrate his invaluable contributions.
In 1963, Jim emigrated to Australia, marking the beginning of a remarkable chapter in his career. He assumed the position of Head, Health and Safety Division at the Australian Atomic Energy Commission (AAEC), now known as ANSTO. Jim played a pivotal role in the foundation of ARPS in 1973, holding the distinguished position of the society's first Vice President. His dedication and vision for ARPS became evident when he assumed the role of newsletter editor in May 1976. Under his guidance, the newsletter evolved into a formalized journal by January 1977, reflecting Jim's commitment to fostering the exchange of knowledge within the community. A transformative moment in ARPS's history was Jim's recommendation that the society should become an affiliate of the International Radiation Protection Association (IRPA). In February 1977, IRPA accepted ARPS as a member society, solidifying its international standing. Jim's leadership continued to flourish as he took on the role of ARPS President in 1977. Jim's influence extended beyond ARPS, as demonstrated by his role as the scientific secretary of the organizing committee for IRPA7 in 1988, held in Sydney. His efforts, along with the committee, led to the successful collaboration with the International Atomic Energy Agency (IAEA), jointly holding its radiation protection conference with IRPA7. In recognition of his exceptional service, Jim was honored with the first ARPS honorary membership at the 14th Annual ARPS conference held in Perth in 1989. Another significant milestone in Jim's illustrious career was his involvement in advocating for professional accreditation in Australia. He played a pivotal role in establishing the accreditation working group, which commenced its efforts at the conference in 1990.
