Opis:
The MCNP6 and MCNPX calculations for the GIT-12 device in Tomsk were performed to determine the influence of the gas-puff hardware on the neutron emission anisotropy and the neutron scattering rate. A monoenergetic 2.45 MeV neutron source and F1 and F6 tallies were declared in the simulation input. A comparison between MCNP results and the measured data was made. Differences between MCNPX and MCNP6 output data were investigated. In the experiment, two nTOF scintillation detectors with the Bicron BC-408 scintillator were used to measure the neutron waveform. Four bubble BD-PND detectors were used to estimate the amount of neutrons in different places around the neutron source.

Opis:
Experiments were carried out on the PF-1000 plasma focus device, with a deuterium filling and with deuterium puffing from a gas-puff nozzle placed on the axis of the anode face. The current was reaching 2 MA. 15 interferometric frames from one shot were recorded with a Nd:YLF laser and a Mach–Zehnder interferometer, with 10–20 ns delay between the frames. As a result, the temporal and spatial distribution of the linear densities and the radial and axial velocities of the moving of plasma in the dense plasma column could be estimated.

Opis:
Coastal areas face greater risk in terms of health and the environment. They are the most vulnerable to impacts resulting from climate change. Coastal areas with higher population density also have more environmental problems, such as natural disasters. Environmental health risks from chemicals and microbes continue threatening people living on small islands. Therefore, this study aims to: 1) conduct a chemical risk analysis of heavy metals Pb, Cr(VI), and Ni; 2) analyse the microbial risk posed by drinking water consumed daily by people on small islands. A method used to analyse the chemical risk of heavy metals was the environment health risk assessment (EHRA), whereas to analyse the microbial risk in small islands, the quantitative microbial risk assessment (QMRA) was used. The results showed that the concentration of heavy metals in drinking water was <0.0012 mg∙dm-3 for Pb, <0.01 mg∙dm-3 for Cr(VI), and <0.0019 mg∙dm-3 for Ni. The three heavy metals showed worrying results. Assessment and obtained risk quotient were less than one (RQ < 1) in all samples. Meanwhile, the microbial analysis found Escherichia coli, Acinetobacter calcoaceticus, Enterobacter sp., and Citrobacter sp., with risk characterised from low to high. Risk management is needed to control environmental health risks posed by heavy metals and the microbiological characteristics of drinking water on the small islands of the Spermonde Archipelago.
