Experimental measurement and Monte Carlo assessment of Argon-41 production in a PET cyclotron facility

Highlights • First reported experimental measurement of41 Ar production near a medical cyclotron. • γ-ray spectrometry analysis confirmed that only41 Ar has a significant production. • An average41 Ar saturation yield Ysat of 3.0 ± 0.6 Bq/µAh*dm3 was measured. • FLUKA direct assessment gave a41 Ar s...

Description
Summary:Highlights • First reported experimental measurement of41 Ar production near a medical cyclotron. • γ-ray spectrometry analysis confirmed that only41 Ar has a significant production. • An average41 Ar saturation yield Ysat of 3.0 ± 0.6 Bq/µAh*dm3 was measured. • FLUKA direct assessment gave a41 Ar saturation yield of 6.9 ± 0.6 Bq/µAh*dm3. • Convolution of cross section with FLUKA neutron fluence gave 6.92 ± 0.22 Bq/µAh*dm3.
