2 Acknowledgment Thanks to my colleagues at, especially to: Sergey Assonov Monika Horsky Sandor Tarjan Joanna Izewska Debbie van der Merwe Ahmed Meghzifene and to our colleagues at BIPM: Robert Wielgosz Joële Viallon Philippe Moussay Steven Judge
3 International Atomic Energy Agency Technical Agency associated to the UN System Atoms for Peace and Development The Agency shall seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world.
4 Overview Long term cooperation with BIPM: 1. Dosimetry and MRA 2. MoU between and BIPM 3. Trace Element Analysis and Nuclear Data 4. Stable Isotope Ratios and Radionuclides
5 1. Dosimetry and the Mutual Recognition Agreement Secondary Standard Dosimetry Laboratories: Provision of calibration for dosimetry equipment. Dosimeters are used to determine dose level for patients, staff or the public importance that measurement results are consistent with SI system (radiation measurements) Formal agreement to establish a Network of SSDLs signed by & WHO (1976) Since 1987, activities of the network are assessed by an independent SSDL Scientific Committee (includes BIPM) MRA signed in 1999 Currently 26 CMCs 86 SSDLs in 71 countries
6 /WHO dose audits for radiotherapy centres How is the audit carried out? Small dosimeters are sent to radiotherapy centres for irradiation to verify the beam output used for patients treatments. Dose audit services : 49 years of the /WHO postal dose audits >13000 beam checks ~2300 radiotherapy centres in 136 Member States BIPM has provided reference irradiations for the /WHO dose audits for >20 years 6
7 Reference irradiations for dose audits : N = 404, m = 1.001, SD =
8 2. Memorandum of Understanding MOU formally signed in 2012, defines the main areas of cooperation: Mutual exchange of data and information in the area of metrology of ionizing radiation and chemical measurements representation in CCRI (full member 2011) participation - as a signatory - in activities related to CIPM MRA BIPM participation in the SSDL Scientific Committee BIPM support to the /WHO dosimetry audits and calibration services through reference irradiations and calibration of reference standards Collaboration for measurement standards and reference materials Publication and dissemination of nuclear data Participation in scientific events (e.g. conferences), education and training, etc. The Dosimetry Laboratory Cs-137 irradiator will be made available to BIPM staff for calibration purposes as of 2019
