O196000100003 AUTHOR (A.Ciarmatori, G.Cicoria, D.Pancaldi, A.Infantino, O196000100004 S.Boschi, S.Fanti, M.Marengo) O196000100005 INSTITUTE (2ITYUBO) University Hospital S.Orsola-Malpighi, O196000100006 Bologna, Italy O196000100007 REFERENCE (J,RCA,99,631,2011) O196000100008 FACILITY (ISOCY,2ITYUBO) a 16.5MeV GE-PETtrace cyclotron. O196000100009 METHOD (STTA) Irradiation time approx. 1 hour O196000100010 (CHSEP) O196000100011 SAMPLE High purity, more than 99.9% yttrium metallic foils. O196000100012 One or two thin discs, thickness = 0.15 mm, diameter = O196000100013 14 mm of Y-89 were firmly positioned in a copper O196000100014 backing support, diameter = 32 mm, depth = 1 mm, havingO196000100015 a central cavity, diameter =14 mm, depth =0.15 or O196000100016 0.30 mm). The target was covered by an aluminium disc O196000100017 of 32 mm diameter and 0.5 mm thickness. O196000100018 The aluminium disc allows for degradation of the energyO196000100019 of the incident proton beam and protects the yttrium O196000100020 target foil from possible motion due to the incident O196000100021 high-pressure helium flow. O196000100022 MONITOR Cu monitor foils were included in the stack to O196000100023 calculate the actual beam current during the O196000100024 irradiation. O196000100025 DETECTOR (HPGE) The high purity Germanium detector has a 30% O196000100026 relative efficiency and a resolution of 1.8 keV at O196000100027 1332 keV. O196000100028 ERR-ANALYS (ERR-T) Total uncertainty includes: O196000100029 (ERR-1,1.,2.).Error in the calibration of the referenceO196000100030 source 1-2% at 1 sigma level, depending on the peak in O196000100031 the mixture. The latter being evaluated from the O196000100032 covariance matrix of the fitting of the efficiency O196000100033 curve (typically less than 3%). The calibration O196000100034 uncertainty thus amounts to about 4-5% at 1 sigma levelO196000100035 (ERR-2,,1.).Error in the tabulated yield typically O196000100036 less than 1%. O196000100037 (ERR-3,,1.).Error in the net peak area less than 1% forO196000100038 for calibration peaks and in the interpolation of the O196000100039 efficiency values. O196000100040 (ERR-4,5.0,7.0).Error in the accuracy in the activity O196000100041 values obtained was in the range 5-7%. Taking into O196000100042 account the accuracy in the dispensing of the samples, O196000100043 the uncertainty in measurements of net areas of samplesO196000100044 typically less than 2% and in positioning of samples, O196000100045 less than 1%, a comparison of the activity values O196000100046 obtained by the gamma ray spectrometry system and the O196000100047 results of the measurements performed with the O196000100048 radionuclide activity calibrator, allows for assessmentO196000100049 of a first order calibration factor for the activity O196000100050 meter, with a level of accuracy of about 8% at 1 sigma O196000100051 level, that is considered satisfactory in the scope of O196000100052 the present work.
