State of the Art in Cyclotrons for Radionuclide Production in Biomedicine / Marengo, Mario (Bologna U.) ; Cicoria, Gianfranco ; Infantino, Angelo (CERN) ; Vichi, Sara ; Zagni, Federico ; Mostacci, Domiziano (Bologna U.)
Cyclotrons are one of the most important sources of radionuclides used in biomedical applications. The production of important radionuclides used in single-photon emission tomography techniques such as 123I, 67Ga, 201Tl, and 111In has been based for decades on cyclotrons, typically proton machines with an energy up to 30 MeV.

Characterization of 41Ar production in air at a PET cyclotron facility / Cicoria, Gianfranco (Unlisted, IT) ; Cesarini, Francesco (Unlisted, IT) ; Infantino, Angelo (CERN) ; Vichi, Sara (Bologna U.) ; Zagni, Federico (Unlisted, IT) ; Marengo, Mario (Unlisted, IT)
In the production of Positron Emission Tomography (PET) nuclides at a medical cyclotron facility 41Ar (T1/2 = 109.34 m) is produced by the activation of air due to the neutron flux, according to the 40Ar(n, γ)41Ar reaction. In this work, we describe a relatively inexpensive and readily reproducible methodology of air sampling that can be used for quantification of 41Ar during the routine production of PET nuclides.

An innovative gamma-ray spectrometry system using a compact and portable CZT detector for radionuclidic purity tests of PET radiopharmaceuticals / Vichi, Sara (Bologna U.) ; Infantino, Angelo (CERN) ; Cicoria, Gianfranco ; Pancaldi, Davide ; Mostacci, Domiziano (Bologna U.) ; Lodi, Filippo ; Marengo, Mario
This work was aimed at characterizing and validating a very compact, USB-powered, CdZnTe detector for gamma-ray spectrometry applications in radiopharmacy. A GR1 model (by KromekTM, Sedgefield, UK) was utilized. [...]

Efficiency calibration of a portable CZT detector for nondestructive activation assessment of a cyclotron bunker / Vichi, Sara (Bologna U.) ; Infantino, Angelo (CERN) ; Zagni, Federico ; Cicoria, Gianfranco ; Marengo, Mario ; Mostacci, Domiziano (Bologna U.)
During the operational life of a PET Cyclotron, the concrete walls of the cyclotron vault are activated by the secondary neutron flux interacting with rare earths and metals present in the concrete or in reinforcement bars. For this reason when considering dismantling of such accelerators, the amount of radioactive waste has to be evaluated in advance to identify any critical issues or possible countermeasures to be taken to define an optimum decommissioning strategy.
