Most of the building materials contain naturally occurring radioactive elements, the most important of which are potassium
40K and the members of two natural radioactive series, which can be represented by the isotopes of thorium 232Th and Uranium 238U. The presence of these radioisotopes in the materials causes external exposure to the people who live in the building. In
addition, the disintegration of Uranium 238U increases the concentration of radon gas 222Rn and of its daughters in the house. So a systematic indoor gamma dose measurement has been performed in the dwellings of
Agastheeswaram Taluk of Kanyakumari district, which is lying within the 30 km radius from the upcoming Kudankulam nuclear
power plant site. The geometric mean of annual absorbed dose from gamma radiation in dwellings has been found to be 278 nGyh−1. The seasonal variation of indoor gamma dose measurements has also been studied. Significant differences have been observed
in dwellings built of different materials such as concrete, tiled, etc. 相似文献

Multicriteria Relocation Analysis of an Off-site Radioactive Monitoring Network for a Nuclear Power Plant 总被引:1,自引:0,他引:1
Due to increasing environmental consciousness in most countries, every utility that owns a commercial nuclear power plant
has been required to have both an on-site and off-site emergency response plan since the 1980s. A radiation monitoring network,
viewed as part of the emergency response plan, can provide information regarding the radiation dosage emitted from a nuclear
power plant in a regular operational period and/or abnormal measurements in an emergency event. Such monitoring information
might help field operators and decision-makers to provide accurate responses or make decisions to protect the public health
and safety. This study aims to conduct an integrated simulation and optimization analysis looking for the relocation strategy
of a long-term regular off-site monitoring network at a nuclear power plant. The planning goal is to downsize the current
monitoring network but maintain its monitoring capacity as much as possible. The monitoring sensors considered in this study
include the thermoluminescence dosimetry (TLD) and air sampling system (AP) simultaneously. It is designed for detecting the
radionuclide accumulative concentration, the frequency of violation, and the possible population affected by a long-term impact
in the surrounding area regularly while it can also be used in an accidental release event. With the aid of the calibrated
Industrial Source Complex–Plume Rise Model Enhancements (ISC-PRIME) simulation model to track down the possible radionuclide
diffusion, dispersion, transport, and transformation process in the atmospheric environment, a multiobjective evaluation process
can be applied to achieve the screening of monitoring stations for the nuclear power plant located at Hengchun Peninsula,
South Taiwan. To account for multiple objectives, this study calculated preference weights to linearly combine objective functions
leading to decision-making with exposure assessment in an optimization context. Final suggestions should be useful for narrowing
the set of scenarios that decision-makers need to consider in this relocation process. 相似文献

Introduction
Young male drivers are over-represented in traffic accidents; they were involved in 14% of fatal accidents from 1991 to 2003 while holding only 8% of all drivers licenses in the UK. In this study, a subset of the UK national road accident data from 1991 to 2003 has been analyzed. The primary aim is to determine how to best use monetary and progressive resources to understand how road safety measures will reduce the severity of accidents involving young male drivers in both London and Great Britain.Method
Ordered probit models were used to identify specific accident characteristics that increase the likelihood of one of three categorical outcomes of accident severity: slight, serious, or fatal.Results
Characteristics found to lead to a higher likelihood of serious and fatal injuries are generally similar across Great Britain and London but are different from those predicted to lead to a higher likelihood of slight injuries. Those characteristics predicted to lead to serious and fatal injuries include driving in darkness, between Friday and Sunday, on roads with a speed limit of 60 mph, on single carriageways, overtaking, skidding, hitting an object off the carriageway, and when passing the site of a previous accident. Characteristics predicted to lead to slight injuries include driving in daylight, between Monday and Thursday, on roads with a speed limit of 30 mph or less, at a roundabout, waiting to move, and when an animal is on the carriageway.Impact on Industry
These results aid the selection of policy options that are most likely to reduce the severity of accidents involving young male drivers. 相似文献429.
储罐爆炸碎片最可能抛射距离的Monte-Carlo(蒙特卡罗)数值模拟 总被引:5,自引:2,他引:3
在总结前人工作的基础上,推导了储罐爆炸碎片抛射距离的理论计算公式,并给出具体的计算方法;分析了计算参数的不确定性,同时介绍用Monte-Carlo方法模拟高压储罐爆炸时碎片抛射距离的算法;在数值模拟结果的基础上,计算了碎片抛射距离的分布函数和概率密度函数,引入最可能抛射距离的概念,并指出可以用此来确定碎片抛射的危害范围。该方法对于定量评价储罐爆炸碎片危害性,减缓和控制碎片产生的风险,具有重要的意义。 相似文献

上海市企业环境污染事故应急预案完备性研究 总被引:2,自引:1,他引:1
在分析企业环境污染事故应急预案编写完备性的基础上,从企业基本情况、潜在事故风险、预防与预警、应急响应和应急保障5方面构建企业环境污染事故应急预案编制完备性评估指标体系,评估了2006—2008年间上海市120家企业编制的环境污染事故应急预案。其结果表明:企业编制的环境污染事故应急预案总体完备性较差;不同企业预案编制的完备性差异明显;编制完备性较好的企业数量少;在所构建的评估指标体系中,不同指标项所占百分比相差悬殊等;最后提出了改进建议。 相似文献
