National intercomparisons of 131I radioactivity measurements in nuclear medicine centres in India

Innovative methodology for intercomparison of radionuclide calibrators using short half-lifein situprepared radioactive sources

“…1 The first intercomparison of radionuclide calibrators was carried out by the College of American Pathologists in the United States of America in the early 1980s. 2 Since then, several countries implemented comparison programs for several radionuclides: United Kingdom, [3][4][5][6][7][8][9][10][11] India, 12,13 Argentina, 14,15 Hungary, 16,17 Germany, 18 Australia, 19 Canada, 20 Brazil, [21][22][23][24] Czech Republic, 25,26 Switzerland, 27 and Cuba. 28 The comparison methodology, as well as the radionuclides used, varied between studies.…”

Traceability in nuclear medicine

“…Just as proficiency testing is important for manufacturers and commercial companies supplying radiopharmaceuticals, similar exercises are helpful in detecting problems with a measurement system at the clinical level. Within the last decade, measurement comparison tests for clinics have recently been organized at the national level and reported on by NMIs in Brazil, Cuba, the Czech Republic, India, the Republic of South Korea, Switzerland and the United Kingdom [25][26][27][28][29][30][31][32]. In most cases, participation in such exercises is voluntary, although national legislation in Cuba and the Czech Republic make such tests mandatory.…”

Teste de proficiência para medições de radioatividade na medicina nuclear

“…Due to the recognition of the quality assurance programs implementation to assure accuracy, repeatability and measurements consistency, it is easy to understand its applicability in nuclear medicine practices (1)(2)(3)(4) . The availability of standards with metrological traceability to 0100-3984 © Colégio Brasileiro de Radiologia e Diagnóstico por Imagem ment comprises an ionization chamber or Geiger-Müller detector coupled with an electrometer with a display whose reading is the activity measured in MBq or Ci submultiples.…”
