Abstract There is little available information on the radioactivity concentrations in the thermal and drinking water sources in North Vietnam. In the current study, the gross alpha and gross beta activity concentrations were determined in 8 water sources in the area. The average activities of gross alpha and beta in the 8 sources are 38.7 mBq L− 1 and 88.0 mBq L− 1. These activity concentrations are lower than WHO recommendations for drinking water. In this study, the gross alpha and gross beta show a weak correlation.

The concentrations of gross alpha and gross beta radioactivity were analyzed in Aniocha South LGA of Delta State. Sediments were collected from randomly selected points on three major rivers in the LGA characterized by human activities, overpopulation, and industrialization. Standard methods were deployed for determination of gross alpha and gross beta radioactivity ineach sample by using an eight channel gas flow proportional counter and also to determine the concentrations of Cd, Pb, Cu and As in the water samples were done using chemical fraction method. The results show that the range of g

In this letter, we study some relevant parameters of the massless Gross-Neveu (GN) model in afinite spatial dimension for different boundary conditions. It is considered the standard homogeneousHartree-Fock solution using zeta function regularization for the study the mass dynamically generated and its respective beta function. It is found that the beta function does not depend on the boundary conditions. On the other hand, it was considered the Casimir effect of the resulting effective theory. There appears a complex picture where the sign of the generated forces depends on the parameters use

Investigation of the natural radioactivity levels in water around power plants, as well as in plants, coal, ash, slag and soil, and to assess the associated radiation hazard is becoming an emerging and interesting topic. This paper is focused on the results of the radioactivity analysis in waste water samples from five coal-fired power plants in Serbia (Nikola Tesla A, Nikola Tesla B, Kolubara, Morava and Kostolac), which were analyzed in the period 2003–2015. River water samples taken upstream and downstream from the power plants, drain water and overflow water were analyzed. In the water sam

Abstract We present microscopic derivations of the defocusing two-dimensional cubic nonlinear Schrödinger equation and the Gross–Pitaevskii equation starting from an interacting N-particle system of bosons. We consider the interaction potential to be given either by $$W_\beta (x)=N^{-1+2 \beta }W(N^\beta x)$$Wβ(x)=N-1+2βW(Nβx), for any $$\beta >0$$β>0, or to be given by $$V_N(x)=e^{2N} V(e^N x)$$VN(x)=e2NV(eNx), for some spherical symmetric, nonnegative and compactly supported $$W,V \in L^\infty ({\mathbb {R}}^2,{\mathbb {R}})$$W,V∈L∞(R2,R).

Abstract The current study was conducted to measure the activity concentration of the gross alpha and beta in 87 groundwater samples collected from the productive aquifers that constitute a major source of groundwater to evaluate the annual effective dose and the corresponding health impact on the population and to investigate the quality of groundwater in Jordan. The mean activity concentration of gross alpha and beta in groundwater ranges from 0.26 ± 0.03 to 3.58 ± 0.55 Bq L−1 and from 0.51 ± 0.07 to 3.43 ± 0.46 Bq L−1, respectively.

Aims: To determine the level of radioactive pollution in soil samples from mining and non-mining communities in Barking Ladi local government area of plateau State and evaluate the implications for public health. Study Design: A Comparative Study was conducted using soil samples collected randomly from mining and non-mining communities (four samples from each). The samples were subjected to analysis for gross alpha and beta radioactivity concentration at the Centre for Energy Research and Training, Ahmadu Bello University, Zaria, using a Protean Instrument Corporation (MPC 2000 Dual Phosphor)

Studies of gross alpha and gross beta activity in road- and surface-deposited sediments were conducted in three Russian cities in different geographical zones. To perform radiation measurements, new methods were applied which allow dealing with low mass and low volume dust-sized (2–100 μm) samples obtained after the size fractionation procedure. The 2–10 μm fraction size had the highest gross beta activity concentration (GB)—1.32 Bq/g in Nizhny Novgorod and Rostov-On-Don, while the 50–100 μm fraction size was most prominent in Ekaterinburg. This can be attributed to the presence of radionuclid
