It is well known that volcanic eruptions represent an important source of natural radionuclide emissions into the environment; however, there are not many studies evaluating their radiological impact. The recent eruption Tajogaite volcano, took place in La Palma Island (Canary Islands, Spain) between September and December 2021, offers opportunity to monitor its impact on both environment nearby population.The eruption, located western site Cumbre Vieja rift zone, lasted 85 days large...
We discuss the modeling of population kinetics nonequilibrium steady-state plasmas using a collisional-radiative model and code based on analytical rates (ABAKO). ABAKO can be applied to low-to-high $Z$ ions for wide range laboratory plasma conditions: coronal, local thermodynamic equilibrium or nonlocal equilibrium, optically thin thick plasmas. combines set approximations atomic rates, which yield substantial savings in computer running time, still comparing well with more elaborate codes...
222Rn has been detected in 28 groundwater samples from the northeast of Gran Canaria (Canary Islands, Spain) utilizing a closed loop system consisting an AlphaGUARD monitor that measures radon activity concentration air by means ionization chamber, and AquaKIT set transfers dissolved water to within circuit. Radon studied varies between 0.3 76.9 Bq/L. Spanish radiological protection regulations limit for drinking 100 Bq/L, therefore values obtained all analyzed are below this threshold. The...
Abstract Radiative properties are fundamental for plasma diagnostics and hydro-simulations. For this reason, there is a high interest in their determination they current topic of investigation both astrophysics inertial fusion confinement research. In work flexible computation package calculating radiative low Z optically thin thick plasmas, under local thermodynamic equilibrium non-local conditions, named RAPCAL presented. This code has been developed with the aim providing accurate medium...

In this work several relevant parameters and properties for krypton xenon plasmas are analyzed, such as, example, the average ionization, plasma thermodynamic regimes, radiative power losses mean opacities. This analysis is performed in a range of density temperature typically found laboratory experiments to generate blast waves laser-heated clustered plasmas. A polynomial fit those also presented. Finally an thermal cooling instability performed.
Numerical simulations of laboratory astrophysics experiments on plasma flows require microscopic properties that are obtained by means an atomic kinetic model. This fact implies a careful choice the most suitable model for experiment under analysis. Otherwise, calculations could lead to inaccurate results and inappropriate conclusions. First, study validity local thermodynamic equilibrium in calculation average ionization, mean radiative properties, cooling times argon plasmas range...
Abstract In this work is accomplished the determination of corona, local and non-local thermodynamic equilibrium regimes for optically thin carbon plasmas in steady state, terms plasma density temperature using ABAKO code. The made through analysis average ionization ion level populations. results are compared whit those obtained applying Griem's criterion. Finally, it a brief effects calculation populations assuming different radiative properties, such as emissivities opacities.
Abstract Plasma radiative properties play a pivotal role both in nuclear fusion and astrophysics. They are essential to analyze explain experiments or observations also radiative-hydrodynamics simulations. Their computation requires the generation of large atomic databases calculation, by solving set rate equations, huge number level populations wide ranges plasma conditions. These facts make that, for example, in-line simulations be almost infeasible. This has lead develop analytical...
