“…2) They all seem to fluctuate around a constant level, and therefore, they may represent a stationary character, but since this does not appear clearly from the figure and for further calculations, a "difference" to the data can be made. We also obtained similar results in our research for 210 Pb [16]. 3) There is no increasing or decreasing trend component in the whole records, 4) A visual inspection indicates that they might have some internal (serial) correlation structure, which must be confirmed by numerical calculations for clear cut deci- sion (As the 40 K counts are high, the detection uncertainty is lower and therefore the dispersion is to find will also be lower), 5) Comparatively, the less fluctuation appears with 40 K records, 6) 226 Ra, and 232 Th have almost the same variability around their respective constant levels, which is referred to as average variability.…”

“…Knowledge on the terrestrial natural radioactivity concentration in the environment plays an important role in determining public exposure levels [1][2][3]. Concerning the natural radioactivity measurements' importance in environment, there are a number of studies in literature [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

“…In this paper, ARIMA models are considered for each radioactive element distribution characteristics determination. In addition, MCSs techniques are efficient and inferential in stochastic assessments [37] to estimate future unknown radionuclides concentrations [16]. There are many studies on MCS related to nuclear [38], medicine [39], engineering [40], and environment [41].…”

This study depicts the radioactivity time series levels of 226 Ra, 232 Th, and 40 K prospectively by Monte Carlo simulations (MCSs). Three ARIMA stationary stochastic processes are used with measurement records statistical parameter conservation. The MCSs by means of the ARIMA stochastic processes, the statistical characteristics of the radionuclide data are determined and the future simulation forecasts are made for different periods (time between two measurements, i.e. 1 week). Future concentrations of radionuclides with MCS are estimated for the first time. The results obtained on the transport, control and management of radionuclides can also reach similar gains for other different materials.

“…Lead (Pb) is a metal that has been used by humans for several thousand years (Gupta et al, 2020), its consumption continues to decrease and its main use is in batteries (Külahcı, 2020). Lead is present in the soil, but also in water, in the air, and in living organisms, it is the most common and toxic element affecting living organisms in the environment (Shahid et al, 2011).…”

Lead is widely used in everyday life, it has important physicochemical properties, and it is a very useful chemical element, abundant but dangerous. In plants, it has no physiological role and is a toxic element. To study the effect of this pollutant physiologically and chemically in bean (Vicia faba L.) plants, different doses of lead in the form of [Pb(NO 3 ) 2 ] (0, 50, 100, 200, 500, 1000, 2000 ppm) were added to the culture substrate consisting of sand and compost. The results of this study showed a reduction in relative water content (RWC) in dry weight and chlorophyll pigment content. The results also showed a significant reduction in sodium (Na) in the roots and stems. The presence of lead caused significant physiological and chemical disturbances.

Around the world, earthquake forecasting studies have become very important nowadays due to the increase in number of fatal earthquakes annually. This paper proposes to achieve a possible relationship between soil radon gas concentration and atmospheric Total Electron Content (TEC) during earthquakes taking into account magnetic effects on the North Anatolian Fault Zone (NAFZ) in Turkiye. The ARIMA and Monte Carlo Simulation (MCS) are employed for determining radon gas concentrations by taking into account magnetic effects as an innovative approach. In the study area relatively small and medium-scale earthquakes have taken place during the observation period. As a result of the investigations, the relationships between each of the parameters and earthquakes are determined, and hence, a good relationship is obtained between Rn gas anomaly and micro-seismic activity. In the ionosphere, geomagnetic activity has a primary impact and long duration on TEC distribution, but due to microseismic events it has rather small in uence. The proposed ARIMA and MCS simulations to detect changes in soil Rn gas concentrations have signi cant results for detecting micro-seismic activity anomalies.
