Online ahead of print.ABSTRACTA new proton beam-line dedicated to R&D programs has been developed at CentreAntoine Lacassagne (CAL), in Nice (France), in collaboration with the Centrenational d'études spatiales (CNES). This is the second beam-line of the MEDICYC 65 MeV cyclotron that is currently in operation, the first being the clinical 'eye-line' used for ocular proton therapy. The R&D beam-line is proposed with two configurations, the first producing a Gaussian narrow beam of a few mm width, the second a 100 mm diameter flat beam wit...

A new generation of scintillation detectors with identification of events undergoing multiple interactions for gamma-ray imaging and spectroscopy
Appl Radiat Isot. 2022 Mar 9;184:110189. doi: 10.1016/j.apradiso.2022.110189. Online ahead of print.ABSTRACTThe present work deals with a scintillation detector made of a LuYAP:Ce array coupled to a position-sensitive photo-multiplier tube, whose structure is well suitable for SPECT and PET, but also in nuclear physics, astrophysics, astroparticle physics, homeland security, and non-proliferation. The response was investigated under Co-57, Ba-133, Cs-137 gamma-ray irradiation, and with Lu-176 self-activity. The investigation, based on the 2-D charge-profiles spread, provides means for identifying and rejecting multiple-int...

Mathematical description of the effect of HIF inhibition on the radiobiological response of LNCaP cells
The objective of the present study was to evaluate the participation of HIF-1α activation in the radiobiological response of the human prostate adenocarcinoma cell line LNCaP, describing the phenomena with a mathematical model. Four groups were formed under different exposure conditions, including hypoxic cells treated with CoCl2 (300 μM for 22 h) with or without hypoxia-inducible factor inhibitor (150 nM chetomin for 4 h added after an incubation period of 18 h with CoCl2, just before completing the incubation period of 22 h). They were exposed to a source of 60Co in a dose range between 2 and 10 Gy to obtain survival c...

Application of an algebraic methodology for the combination of Berthold LB6411 and WENDI-II for neutron area monitoring in D-T neutron generators and fusion facilities
The objective of this work is to establish a methodology to combine the dose response functions of Berthold LB6411 and WENDI-II, adjusting this combined function to the ICRP74 conversion function: this combination shows an almost perfect adjustment between 0.5 and 20 MeV. Thus, this article presents an easy and cheap alternative to the recalibration in D-T generators.PMID:35272229 | DOI:10.1016/j.apradiso.2022.110179 (Source: Applied Radiation and Isotopes)
