The radioactivity of nuclides and content of heavy elements in soil, water and air are commonly important criteria in the environmental assessment of the mining areas. The study within the years of 2016-2018 on radioactivity and heavy elements content in the water and air samples at Lai Chau Rare Earth project (belonged to Dong Pao rare earth mine area) is to support the environmental survey and assessment program running by environment agency to manage the individually environmental mining area.

Proposed construction of or changes to a radiological effluent stack must meet the mixing criteria at the sampled stack location required by the standards ANSI/HPS N13.1–2011 and ISO 2889. For more than a decade, threedimensional computational fluid dynamics (CFD) models of such stacks have been used to assist in characterizing the sample location suitability.

This study investigates radioactivity in the ambient air for a district in Hanoi capital, Vietnam, in the period 2015 - 2018. Aerosol samples are collected by Taifful (Тайфун, Russia) equipment, using ΦПП 15-3p filter, to determine the 40K, 238U, and 232Th concentration by gamma spectrometry method and following the STI/DOC 010/295 TRS 295-IAEA-1989 guidelines.

The objective of this research is to obtain the transport parameters of some radionuclides in the air to create the input data for a model to simulate the atmospheric dispersion of the radioactive materials and to assess the public dose around nuclear facilities.

In this paper we propose a method for the creation of oxide layers on stainless steel 304L with europium (Eu) as contaminant. This technique consists in spraying an Eu-solution on stainless steel samples.

About 10% of total electricity (386 MkW) was generated by nuclear power plants in the world (2014) and about 58,400 tons of uranium has been mined in uranium mines annually. A plenty of radioactive waste material is produced from uranium mines and nuclear power plants. The wastes must be disposed or stored safely for a long term. Because if they leak and/or move from disposal or storage sites due to air/groundwater flow, then a serious environmental pollution can occur.

When it is necessary to add refrigerant to a system after a loss it indicates that there is a leak in the system. The leak must be located, repaired and the system leak tested. If the leak is found to be on the low side of the system the repair can be made after the system has been ‘pumped down’ to a balance in pressure. Do not draw in any air which contains moisture, especially where hygroscopic ester oils are concerned, (for example R134a). Some oils are not affected and accept the ingress of air and moisture, recovering after a vacuum is drawn with a recovery unit....

When planning how to reduce the threat of global warming and how to adapt to it, a very important piece of information is how intense the change will be. That implies estimating the trends of future concentrations of greenhouse gasses, and the potential future changes in temperature, precipitation, storm events and other climatic variables. These predictions are important not only to estimate the magnitude of the changes, but also to determine the uncertainty surrounding them.

The atmosphere may be our most precious resource. Accordingly, the balance between its use and protection is a high priority for our civilization. While many of us would consider air pollution to be an issue that the modern world has resolved to a greater extent, it still appears to have considerable influence on the global environment. In many countries with ambitious economic growth targets the acceptable levels of air pollution have been transgressed. Serious respiratory disease related problems have been identified with both indoor and outdoor pollution throughout the world....

Since the Second World War, and especially since the publication of Rachel Carson’s Silent Spring in 1962, there has been growing concern about contamination of the environment by “man-made” chemicals. These chemicals may be present in industrial and municipal effluents, in consumer or commercial products, in mine tailings, in petroleum products, and in gaseous emissions. Some chemicals such as pesticides may be specifically designed to kill biota present in natural or agricultural ecosystems. They may be organic, inorganic, metallic, or radioactive in nature.
