In this paper the authors discuss a method using 1-nm particulate radon decay products as an experimental tool in the study of local lung deposition and dosimetry for nanoaerosols. The study of aerosol exposure and dosimetry measurements, and related quantitative assessment of health effects, are important to the understanding of the consequences of air pollution, and are discussed widely in th...

We investigate the release of radioactive contaminants from Moruroa Atoll in a global high-resolution off-line model. The spread of tracer is studied in a series of simulations with varying release depths and time-scales, and into ocean velocity fields corresponding to long-term annual mean, seasonal, and interannually varying scenarios. In the instantaneous surface release scenarios we find th...

Detecting changes in humans that result from radioactive contamination of the area of residence many years after an incident (i.e., when the radiation has substantially decayed) presents a difficult epidemiological problem. Problems of this kind are even more complicated ina areas where the population is continually exposed to other harmful man-made factors. The city of Kamensk-Uralsky (Sverdlo...

The present nuclear leakage crisis from Japan is a topic to be discussed in present public health. In radiology, the leaked radioactive elements are considered hazard. Here, the author briefly reviews and discusses on two important radio-hazard elements in post nuclear power plant crisis, radioactive iodine and radioactive cesium. Based on previous similar nuclear crisis in Russia, it ...

introduction: one of the sources of natural occurring radiation was soils. the purpose of article was to determine soil pollution by radiation absorbed dose rate, radium equivalent activity, external hazard index, annual gonad dose equivalent and annual effective dose equivalent. methods & materials: the soil samples was located in chahbahar city in blouchestan of iran, was chosen for studying ...

Electrokinetic remediation (EKR) is a powerful technique aimed at pollutant removal in soil, sludge, mine tailings, and so on. In the current work, we performed bibliometric analysis of research on EKR for period 1900–2018 basis core database Science Citation Index Expanded. addition to basic characteristics, keywords were analysed four major participants: USA, China, Spain, South Korea. The pe...

Background: The Ural region is highlighted among other Russian regions for its unfavorable radiation situation and complexity of the overall environmental situation. The source of man-made radioactive contamination is the work of the "Mayak" Production Association. A significant radioactive contamination has happened as a result of several radiation incidents in the early period ...

The problem of water pollution is now a problem of commons, round the globe [1], but the problem of arsenic contamination in the groundwater is not too old. Arsenic (As) is a metalloid and it belongs to Nitrogen Group [Va] of the periodic table. The atomic number of Arsenic is 33 and atomic mass is 74.922. Arsenic is found as one stable isotope, 75As which is non-radioactive. Arsenic appears in...

The article proposes an urgent task to increase the level of environmental safety radioactively contaminated areas. main tasks are develop new methods monitoring; study migration processes radioactive elements in soil cover order predictive models for timely identification areas at risk contamination; establishing relationships between state contamination by radionuclides and their genesis iden...

A recent trend in the development of high mass consumption electron devices is towards electronic textiles (e-textiles), smart wearable devices, smart clothes, and flexible or printable electronics. Intrinsically soft, stretchable, flexible, Wearable Memories and Computing devices (WMCs) bring us closer to sci-fi scenarios, where future electronic systems are totally integrated in our everyday ...
