A reliable and highly scalable Internet of Things (IoT) end-to-end data infrastructure has been developed for environmental radiation monitoring at the European Organization Nuclear Research (CERN) based on a low-power wide-area network (LPWAN). The proposed system, called Waste MONitoring (W-MON), consists an interconnected thousands sensitive ultralow-power gamma sensors acting as long range (LoRa) transceivers. aim system is to improve automatize radiological controls conventional waste...
The 'history' of the extended range neutron rem counter LINUS, since its first conception in 1990, is reviewed, along with latest developments. These include calibration initially cylindrical version nearly monoenergetic neutrons energy 34-66 MeV, a detailed evaluation anisotropy response function, construction and an improved spherical version, recent measurements reference high stray radiation fields. instrument can now be considered as being fully characterised. Similar monitors built by...
Passive and active detection techniques have been employed in order to measure neutron fluence rates corresponding exposure around medical electron accelerators operating at energies well above the binding of structural materials. In these conditions from treatment head, direct photon flux shielded region, a fast emerges which is partly absorbed scattered by walls, eventually establishing nearly uniform thermal epithermal room. Both contribute dose patient. A smaller rate can also be found...
In the framework of EURADOS working group 11, an intercomparison active neutron survey meters was performed in a pulsed field (PNF). The aim exercise to evaluate performances various instruments, including commercially available rem-counters, personal dosemeters and instrument prototypes. measurements took place at cyclotron Helmholtz-Zentrum Berlin für Materialien und Energie GmbH. is routinely used for proton therapy ocular tumours, but experimental area also available. For machine...
Bent silicon crystals mounted on high-accuracy angular actuators were installed in the CERN Super Proton Synchrotron (SPS) and extensively tested to assess feasibility of crystal-assisted collimation circular hadron colliders. The adopted layout was exploited regularly upgraded for about a decade by UA9 Collaboration. investigations provided compelling evidence strong reduction beam losses induced nuclear inelastic interactions aligned comparison with amorphous orientation. A conceptually...
In hadron therapy, out-of-field doses, which may in the long-term cause secondary cancers, are mostly due to neutrons. Very recently, 4He and 16O beams have been added protons 12C ions for clinical therapy. The focus of this article is compare neutron doses produced by protons, 4He, 12C, ion beams. Ambient dose equivalent, H*(10), measurements were performed, with five types rem counters, field four primary impinging on a water phantom. This experiment was performed at Heidelberg Ion Beam...
LUPIN-II is an upgraded version of LUPIN, a novel rem counter first developed in 2010 specifically conceived to work pulsed neutron fields (PNFs). The new introduces some modifications that improve the performance detector, particular extending its upper detection limit PNFs. This paper discusses characteristics and instrument. Measurements have been carried out radiation characterized by very different conditions: detector has exposed PNFs with intensity up 5 μSv per burst, where it could...
Abstract Hadron therapy is an advanced radiation modality for treating cancer, which currently uses protons and carbon ions. Hadrons allow a highly conformal dose distribution to the tumour, minimising detrimental side-effects due received by healthy tissues. Treatment with hadrons requires sub-millimetre spatial resolution high dosimetric accuracy. This paper discusses design, fabrication performance tests of detector based on Gas Electron Multipliers (GEM) coupled matrix thin-film...
The well-known Andersson-Braun rem counter is widely employed for radiation protection purposes, but its efficiency shows a marked decrease neutron energies about 10 MeV. Since the availability of survey meter with good sensitivity to higher can be very useful, instance, at many particle accelerator facilities, monitor response function extended up 400 MeV has been achieved by modifying structure moderator-attenuator commercial instrument. first experimental tests carried out verify new both...
Since 2012, the European Radiation Dosimetry Group (EURADOS) has developed its Strategic Research Agenda (SRA), which contributes to identification of future research needs in radiation dosimetry Europe. Continued scientific developments this field necessitate regular updates and, consequently, paper summarises latest revision SRA, with input regarding state art and vision for contributed by EURADOS Working Groups through a stakeholder workshop. Five visions define key issues that are...
Objective Proton therapy is gaining popularity because of the improved dose delivery over conventional radiation therapy. The secondary to healthy tissues dominated by neutrons. Commercial rem-counters are valuable instruments for on-line assessment neutron ambient equivalent (H*(10)). In general, however, a priori knowledge type facility and field required proper choice any survey meter. novel Mevion S250i Hyperscan synchrocyclotron mounts accelerator directly on gantry. It provides scanned...
