International Symposium on Standards, Applications and Quality Assurance in Medical Radiation Dosimetry (IDOS 2019)

18 Jun 2019, 08:00 → 21 Jun 2019, 14:00 Europe/Vienna

IAEA - Vienna International Centre

The major goal of the symposium is to provide a forum at which advances in radiation dosimetry, radiation medicine, radiation protection and associated standards made over the last decade can be disseminated and scientific knowledge exchanged. It will cover all specialties in radiation medicine and radiation protection, with a specific focus on those areas where the standardization of dosimetry has improved in recent years (advanced radiotherapy, diagnostic radiology, nuclear medicine and audits). It will also summarize the present status of, and outline future trends in, medical radiation dosimetry and identify possible areas for improvement. The conclusions and summaries from the symposium should lead to the formulation of recommendations for the scientific community.

The symposium will consist of 16 sessions: four sessions per day of approximately 90 minutes each, including the opening session, educational courses, a series of topical sessions with oral and poster presentations, a session for poster highlights and three round-table discussion sessions.

The opening session will include welcoming addresses followed by two keynote presentations on the history of dosimetry and the main developments in dosimetry since the previous IAEA symposium on the topic (IDOS 2010), which was held in Vienna in November 2010.

A series of topical sessions (four plenary) will then cover selected areas of medical radiation dosimetry, from standards laboratories to the medical applications in radiotherapy, diagnostic radiology and nuclear medicine. Each topical session will include one or two keynote invited presentations of 30 minutes followed by four to six oral presentations and related discussions.

Poster presentations for each topic will be an important component of the symposium, and their display will be maintained during the symposium. A plenary session will be dedicated to the highlights of the posters. The rapporteurs will summarize each of the sessions and prepare recommendations.

On days 1 to 3, a plenary session will be dedicated to a round-table discussion.

The symposium will include a plenary session to highlight fifty years of IAEA/World Health Organization (WHO) dosimetry audits.

The symposium will cover recent developments (outlined in Scientific Programme) in the field of radiation dosimetry standards, applications and quality assurance.
