Atmospheric dispersion modeling and radiation dose calculations have been performed for a hypothetical AP1000 SGTR accident by HotSpot code 3.03. TEDE, the respiratory time-integrated air concentration, and the ground deposition are calculated for various atmospheric stability classes, Pasquill stability categories A–F with site-specific averaged meteorological conditions. The results indicate that the maximum plume centerline ground deposition value of1.2E+2 kBq/m2occurred at about 1.4 km and the maximum TEDE value of1.41E-05 Sv occurred at 1.4 km from the reactor. It is still far below the annual regulatory limits of 1 mSv for the public as set in IAEA Safety Report Series number 115. The released radionuclides might be transported to long distances but will not have any harmful effect on the public.

Determination of urgent countermeasures to protect the public in early phase of the accident at NPP requires providing of radiological impact assessment at different distances in real time. These activities involve current meteorological forecast data and information about source term parameters as one of the main part of the emergency сenters functioning worldwide for prompt notification about the radiological or nuclear event in the country, as well as abroad in the case of transboundary impact. Experts’ background in the assessment and forecasting of radiological consequences area may vary from country to country in terms of methodological approaches, the use of atmospheric dispersion models, doses assessment models, databases, organization procedures, calculation process etc. Possible deviations in the results of assessments performed by experts from different countries may be caused by a number of factors. Their reasons can vary from the use of different information sources to the specifics of protective actions criteria in accordance with national requirements. These factors should be identified both in practice and scientifically. Radiological consequence assessment activities are harmonized at the international level. It is the target of a wide range of international projects. The paper provides information on modern scientific initiatives aimed at improving assessments and forecasts of radiological consequences to determine urgent countermeasures to protect the public at early phases of an accident at nuclear power plant, in particular, approaches to the initial data preparation and the conduct of assessments and forecasting. A review of international benchmarking activities as well as past emergency exercise overview is presented in the paper. Relevant problems of forecasting radiological consequences in real time are highlighted.

AbstractIf we want psychological science to have a meaningful real-world impact, it has to be trusted by the public. Scientific progress is noisy; accordingly, replications sometimes fail even for true findings. We need to communicate the acceptability of uncertainty to the public and our peers, to prevent psychology from being perceived as having nothing to say about reality.

The Court of Appeals of New York held, in Council of the City of New York u. Giuliani, slip op. 02634, 1999 WL 179257 (N.Y. Mar. 30, 1999), that New York City may not privatize a public city hospital without state statutory authorization. The court found invalid a sublease of a municipal hospital operated by a public benefit corporation to a private, for-profit entity. The court reasoned that the controlling statute prescribed the operation of a municipal hospital as a government function that must be fulfilled by the public benefit corporation as long as it exists, and nothing short of legislative action could put an end to the corporation's existence.In 1969, the New York State legislature enacted the Health and Hospitals Corporation Act (HHCA), establishing the New York City Health and Hospitals Corporation (HHC) as an attempt to improve the New York City public health system. Thirty years later, on a renewed perception that the public health system was once again lacking, the city administration approved a sublease of Coney Island Hospital from HHC to PHS New York, Inc. (PHS), a private, for-profit entity.

In many respects, the least important part of the 1999 elections were the elections themselves. From the beginning of General Abdusalam Abubakar’s transition program in mid-1998, most Nigerians who were not part of the wealthy “political class” of elites—which is to say, most Nigerians— adopted their usual politically savvy perspective of siddon look (sit and look). They waited with cautious optimism to see what sort of new arrangement the military would allow the civilian politicians to struggle over, and what in turn the civilians would offer the public. No one had any illusions that anything but high-stakes bargaining within the military and the political class would determine the structures of power in the civilian government. Elections would influence this process to the extent that the crowd influences a soccer match.
