Abstract

The assessment of the exposure to cosmic radiation onboard aircraft is one of the preoccupations of bodies responsible for radiation protection. Cosmic particle flux is significantly higher onboard aircraft than at ground level and its intensity depends on the solar activity. The dose is usually estimated using codes validated by the experimental data. In this paper, a comparison of various codes is presented, some of them are used routinely, to assess the dose received by the aircraft crew caused by the galactic cosmic radiation. Results are provided for periods close to solar maximum and minimum and for selected flights covering major commercial routes in the world. The overall agreement between the codes, particularly for those routinely used for aircraft crew dosimetry, was better than ±20 % from the median in all but two cases. The agreement within the codes is considered to be fully satisfactory for radiation protection purposes

Abstract

Monte Carlo (MC) codes are increasingly spreading in the hadrontherapy community due to their detailed description of radiation transport and interaction with matter. The suitability of a MC code for application to hadrontherapy demands accurate and reliable physical models for the description of the transport and the interaction of all components of the expected radiation field (ions, hadrons, electrons, positrons and photons). This contribution will address the specific case of the general-purpose particle and interaction code FLUKA. In this work, an application of FLUKA will be presented, i.e. establishing CT (computed tomography)-based calculations of physical and RBE (relative biological effectiveness)-weighted dose distributions in scanned carbon ion beam therapy.

Abstract

The assessment of radiation damage to electronics is a complex process and requires a detailed description of the full particle energy spectra, as well as a clear characterization of the quantities used to predict radiation damage. FLUKA, a multi-purpose particle interaction and transport code, is capable of calculating proton-proton and heavy ion collisions at LHC energies and beyond. It correctly describes the entire hadronic and electromagnetic particle cascade initiated by secondary particles from TeV energies down to thermal neutrons, and provides direct scoring capabilities essential to estimate in detail the possible risk of radiation damage to electronics. This paper presents the FLUKA capabilities for applications related to radiation damage to electronics, providing benchmarking examples and showing the practical applications of FLUKA at CERN facilities such as CNGS and LHC. Related applications range from the study of device effects, the detailed characterization of the radiation field and radiation monitor calibration, to the input requirements for important mitigation studies including shielding, relocation or other options.

Abstract

The multi-purpose particle interaction and transport code FLUKA is integral part of all radiation protection studies for the design and operation of the Large Hadron Collider (LHC) at CERN. It is one of the very few codes available for this type of calculations which is capable to calculate in one and the same simulation proton-proton and heavy ion collisions at LHC energies as well as the entire hadronic and electromagnetic particle cascade initiated by secondary particles in detectors and beam-line components from TeV energies down to energies of thermal neutrons. The present paper reviews these capabilities of FLUKA in giving details of relevant physics models along with examples of radiation protection studies for the LHC such as shielding studies for underground areas occupied by personnel during LHC operation and the simulation of induced radioactivity around beam loss points. Integral part of the FLUKA development is a careful benchmarking of specific models as well as the code performance in complex, real life applications which is demonstrated with examples of studies relevant to radiation protection at the LHC.

Abstract

Objectives: This research aims to provide child malnutrition prevalence data from Haiti's Milot Valley to inform the design and implementation of local health interventions. Study design: This cross-sectional study measured underweight, stunting, and wasting/thinness using international growth standards. Methods: Anthropometric measurements (height/length and weight) were taken on a convenience sample of 358 children aged 0--14 years. Participants were recruited through door-to-door field visits at five recruitment sites in the Milot Valley, including individuals in the waiting area of the Pediatric Outpatient Clinic at Hopital Sacre Coeur. Caregivers were asked questions about the child's health history, including past and current feeding practices. Results: Combining moderate and severe forms of malnutrition, 14.8% of children under five were stunted, 15.3% were wasted, and 16.1% were underweight. Among children 5--14 years of age, 14.1% were stunted, 7.6% were thin (low body mass index (BMI)-for-age), and 14.5% were underweight. For children under five, 42% of mothers ended exclusive breastfeeding before the recommended six months. Conclusion: This study illustrates the local magnitude of childhood malnutrition and can serve as a resource for future child health interventions in the Milot Valley. To fight malnutrition, a multipronged, integrated approach is recommended, combining effective community outreach and monitoring, inpatient and outpatient nutrition therapy, and expanded partnerships with nutrition-related organizations in the region.
