First Announcement

Conference Description

The International Committee for Radionuclide Metrology (ICRM) is pleased to announce that its next conference will be organized by Institutul Naţional de Cercetare-Dezvoltare pentru Fizică şi Inginerie Nucleară “Horia Hulubei” (IFIN-HH), Bucharest-Măgurele, Romania, during the period March 27 – 31, 2023.

The main purpose of the conference is to enhance the international collaboration in the field of radionuclide metrology by presenting new developments and applications and facilitating the exchange of scientific information between the participants.

The most recent biennial ICRM conference was held at Salamanca (Spain) in 2019 and was organized by the International Committee for Radionuclide Metrology (ICRM) and the Laboratorio de Radiaciones Ionizantes – Datación from Universidad de Salamanca. The ICRM Low Level Radioactivity Measurement Techniques international conference (ICRM LLRMT 2022) was held recently, during May 2-6, 2022, in Assergi, Italy,

The ICRM 2023 conference will include oral and poster presentations and business meetings of the ICRM and its working groups in several application areas of radionuclide metrology.

Radionuclide Metrology at IFIN-HH

IFIN-HH is one of the most important research institutes in Romania, It originates from the Physics Institute of the Romanian Academy, founded by Prof. Horia Hulubei, in 1949 (the Institute of Atomic Physics (IFA), since 1956). The institute is dedicated to the research and development in physical and natural sciences, mainly Nuclear Physics and Nuclear Engineering, and in related areas including Astrophysics and Particle Physics, Field Theory, Mathematical and Computational Physics, Atomic Physics and Physics of Condensed Matter, Life and Environmental Physics.

The Radionuclide Metrology Laboratory (RML) at IFIN-HH, Romania, was established with Dr. Leon Enric Grigorescu (1932-2020) as its first head, in 1966. He was the Head of the laboratory for many years, with a number of remarkable achievements. After his retirement in 2003, Dr. Maria Sahagia took over as Head of the laboratory (until 2017) and had very important contributions to the development of the laboratory.
In 2017, Dr. Aurelian Luca became the laboratory head. The traditional radionuclide metrology research performed at RML led to original and important contributions that have been recognized by the ICRM community (absolute methods for the activity standardization of radionuclides, source preparation, nuclear decay data evaluation, gamma-ray spectrometry). Now, there are also new scientific applications under development, based on Monte Carlo simulation methods, alpha-particle measurements and metrology for radon monitoring (222Rn).

The International Research Center Extreme Light Infrastructure – Nuclear Physics (ELI-NP),, is the most important research infrastructure in Romania. This project, implemented by IFIN-HH, is co-financed by the European Commission and the Romanian Government from Structural Funds via the European Regional Development Fund.

Call for papers

Scientific papers on the topics listed above are welcome. Authors wishing to submit a paper for the conference should send an Abstract to the Scientific Secretariat, using the online form to be available soon on the web page of the conference,, until October 14th, 2022.
The abstracts should be sufficiently detailed, containing relevant scientific information about the originality and importance of the results obtained by the authors. Notification of acceptance will be sent to the authors before the end of November, 2022.


It is intended to publish the proceedings of the conference in the journal Applied Radiation and Isotopes ( The manuscripts, written exclusively in English, will be submitted after the end of the conference and will comply with the guidelines of the journal, which will be sent to the authors, together with the information on the acceptance of the work to be presented at the conference.
The acceptance of a work for presentation at the conference, does not imply its publication in the proceedings. Only a selection of the manuscripts will be published in the journal, after a strict peer-review procedure.
