چکیده
To devise an activation technique for characterizing mixed radiation fields, secondary particles from a copper target irradiated by 24 GeV/c protons were measured at the CERN High-energy AcceleRator Mixed field facility (CHARM). Activation detector sets consisting of aluminum, niobium, indium, and bismuth, placed 30 cm angles 15° to 160° with respect beam axis. The nuclides generated in these detectors due irradiation analyzed γ-ray spectrometry, angular distributions production rates obtained. results Monte Carlo calculations using FLUKA code was compared experimental results. calculated well agreed data all angles. influence competitive reactions on also evaluated FLUKA. following nuclear reactions, low affectivity identified as promising tools fields: 115In(n, n′)115mIn reaction detecting neutrons emitted evaporation process, 93Nb(γ, n)92mNb verifying photon distribution neutral-pion decay (π0→2γ), 209Bi(p, 4n)206Po reaction, which detects protons.

Particle Emissions from Animal Husbandry
Apart from industry, traffic and private households, the agricultural sector is a considerable contributor to emissions of particulate matter (PM). Agricultural activities such as plant and animal production on both farm sites and fields cause PM emissions. Although a reduction of PM emissions is observed for Europe, an increasing proportion of primary PM10 emissions originates from agriculture...
متن کاملA New Modified Particle Filter With Application in Target Tracking
The particle filter (PF) is a novel technique that has sufficiently good estimation results for the nonlinear/non-Gaussian systems. However, PF is inconsistent that caused mainly by loss of particle diversity in resampling step and unknown a priori knowledge of the noise statistics. This paper introduces a new modified particle filter called adaptive unscented particle filter (AUPF) to overcome th...
متن کاملDiffusion of Ultra High Energy Protons in Galaxy Clusters and Secondary X and Gamma Ray Emissions
In this work we simulate the propagation of Ultra High Energy (UHE) protons in the magnetised intergalactic medium of Galaxy Clusters (GCs). Differently from previous works on the subject, we trace proton trajectories in configurations of the Intra Cluster Magnetic Field (ICMF) which have been extracted from a constrained Magnetic-SPH simulation of the local universe. Such an approach allows us...
متن کاملMortality from Copper Smelter Emissions Circa 1967
Pope et al. (2007) found lowered monthly mortality rates during a 1967–1968 copper smelter strike, coincident with and attributed to widespread reduced airborne sulfate levels. The authors cited three “intervention” studies associating particulate emissions reductions with mortality reductions as supportive. Evidence below suggests that mortality reductions in the study by Pope et al. and “inte...
متن کاملAirborne measurements of trace gas and aerosol particle emissions from biomass burning in Amazonia
As part of the LBA-SMOCC (Large-Scale Biosphere-Atmosphere Experiment in Amazonia – Smoke, Aerosols, Clouds, Rainfall, and Climate) 2002 campaign, we studied the emission of carbon monoxide (CO), carbon dioxide (CO2), and aerosol particles from Amazonian deforestation fires using an instrumented aircraft. Emission ratios for aerosol number (CN) relative to CO (ERCN/CO) fell in the range 14–32 c...
