background: in this study, measurement of indoor radon and its progeny levels was carried out in gas turbine power station in haryana ( india ), where natural gas is used as fuel. for comparison, the results of a study carried out in thermal power plant in haryana are also presented. radon being a ubiquitous air pollutant has global impact and its monitoring in the environment at work places is...

About this lab The natural environment involves nuclear radiation. Mankind has added to this by production of power and by application of “artificial” radiation to medical and other uses. After a hiatus of decades in the United States (but not in the rest of the world) nuclear fission power plant construction may experience a revival, under the economic pressure of fossil fuel price increases a...

Our study focused on radiocaesium (137Cs) partitioning in forests, three vegetation periods after the Fukushima Daiichi nuclear power plant accident. 137Cs distribution in forest components (organic and mineral soil layers as well as tree compartments: stem, bark, needles, branches and roots) was measured for two Japanese cedar stand ages (17 and 33 years old). The results showed that around 85...

The purpose of the study was to investigate whether proximity to nuclear power plants may increase the risk of abnormal pregnant outcomes among the resident women. In this ecological study, data were used from the Health Services Birth Reports Database established by the Bureau of Health Promotion, National Department of Health, Taiwan, in 2001-2004. Chi-square-tests were carried out to investi...

Decision making as a part of nuclear power plant operations is a critical, but common, task. Plant management is forced to make decisions that may have safety and economic consequences. Formal decision theory offers the potential for a structured approach capable of taking into account risk-related aspects (plant and worker safety, for instance) and, at the same time, important factors like eco...

To estimate the consequences of radionuclide spread during nuclear power plant accidents, atmospheric dispersion simulation models such as Gaussian Plume Model, Lagrangian Trajectory Model are widely used. However, they require a complex set of meteorological data. Yet, the historical data is not consistently available because of the lack of observed meteorological indicators in some situations...

On March 11, 2011, an earthquake led to major problems at the Fukushima Daiichi Nuclear Power Plant. A 14-m high tsunami triggered by the earthquake disabled all AC power to Units 1, 2, and 3 of the Power Plant, and carried off fuel tanks for emergency diesel generators. Despite many efforts, cooling systems did not work and hydrogen explosions damaged the facilities, releasing a large amount o...
