1. Avaliação do potencial genotóxico do 51Cr2O3, marcador de digestibilidade, por meio da frequência de anormalidades nucleares em tilápias do Nilo (Oreochromis niloticus L.) / The evaluation of genotoxic potential of 51Cr2O3, a digestibility marker, by the frequency of nuclear abnormalities in Nile tilapia (Oreochromis niloticus L.)
Tilapia is the common name of a large number of species of cichlid fish. In aquaculture, this is one of the most profitable fish, since it presents lower feed conversion than other fish. The chromium oxide has been used as a marker for digestibility because it is inert and not alter the biological process of dietary intake. The use of radioactive form of chr

2. Percepção pública das instalações nucleares / Public perception of nuclear installations
The key for nuclear renaissance is public acceptance. Facing energetic needs that occur around the world and lack of resources, the work of characterizing and proposing new models to represent public opinion is extremely important to all stakeholders. Even though public opinions study on risks is relatively recent, may approaches of this subject have been su

3. Serrapilheira aplicada como biomonitor na avaliação do bosque urbano do Instituto de Pesquisas Energéticas e Nucleares, São Paulo,SP / Litterfall as biomonitors applied the evaluation of urban forest of the Nuclear and Energy Research Institute, São Paulo, SP
Several processes are considered responsible for ecosystems maintaining. Among them we can highlight mineral cycling that corresponds to the cycle of chemical elements that flow between the biotic compartments, leaves and litterfall, and abiotic, atmosphere and soil. These chemical elements accumulate of the active form through the absorption in the tissues

4. Uma contribuição para a área de saúde por meio da verificação do impacto da qualidade de energia e das instalações elétricas nos equipamentos eletromédicos. / A contribution to the health area by means an assessment of the impact of quality of power and of electrical installations upon electromedical equipment.
Em todos os segmentos da sociedade, a utilização de equipamentos eletrônicos projetados e construídos com avançadas tecnologias eletrônicas e controlados por microprocessadores aumenta a cada dia. Na área de saúde, denominados de equipamentos eletromédicos, dão suporte aos setores de diagnóstico, tratamento ou, procedimento cirúrgico, melhorando

5. Análise de requisitos normativos para o desenvolvimento e a implementação de um sistema de gestão da qualidade em instalações e atividades nucleares brasileiras / Analysis of normative requirements for the development and implementation of a quality management system in Brazilian nuclear installations and activities
The present work identifies, characterizes and analyses the normative requirements for the development and implementation of quality management systems in Brazilian nuclear installations and activities. The requirements established in standards IAEA GS-R-3, IAEA GS-G-3.1, IAEA DS 349, NBR ISO 9001:2000 e CNEN-NN-1.16 are critically analyzed. A correlation ma

6. O modelo do sistema viável na concepção da arquitetura de sistemas de informação: aplicação no contexto de incidentes em instalação de pesquisa na área nuclear. / The Viable System Model (VSM) in the conception of information system architectures - an application in the context of incidents for a research nuclear installation.
The present work presents a study aiming to verify the applicability of the Viable System Model (VSM) in a robust architecture for an Information System targeting nuclear naval area. The emphasis of the study is in assessing an alternative modeling for the Information System (IS) architecture specification, incorporating a set of functionalities defined by t

7. Survey of the primary radiological and hydrodynamic conditions of the land and surrounding areas to the new installations of crcn/cnen / Levantamento das condiÃÃes radiolÃgicas primÃrias e hidrodinÃmicas do terreno e Ãreas circunvizinhas Ãs novas instalaÃÃes do CRCN/CNEN
Estudos radiomÃtricos foram realizados na Ãrea circunvizinha ao Centro Regional de CiÃncias Nucleares (CRCN). Foram determinadas as concentraÃÃes de 238U, 226Ra, 210Pb e 210Po em amostras de Ãguas e solos, com o objetivo de compor um banco de dados que subsidiarà um Programa de MonitoraÃÃo RadiolÃgico Ambiental (PMRA) prÃ-operacional do CRCN.

8. Um estudo simplificado da percepção pública dos benefícios e riscos de centrais termonucleares - sugestões para a comunicação de valor com o público / Public perception on the benefits and risks of nuclear power plants_a simplified study
Public acceptance of the nuclear based electricity generation depends on many variables that can be affected by circumstances and interests, which although seemingly not close to the issue, can strongly influence the final outcome. Explicit or consented positions assumed by opinion makers and some segments of society are subject to episodic waves of interact

9. Evaluation of the waste profile from (medical) health services of Belo Horizonte concerned to the presence of radioactive wastes in the disposal system / Avaliação do perfil dos resíduos de serviços de saúde de Belo Horizonte quanto à presença de rejeitos radioativos na destinação final
The medical procedures of diagnosis and treatment that use radiopharmaceuticals generate radioactive wastes that can, after reaching the release limit, follow the conventional ways of collection and disposal of the urban solid wastes. This research aims to detect radiometrically the presence of radioactive wastes in the health-care wastes at the final dispos

11. On statistical methods for analysing the geographical distribution of cancer cases near nuclear installations.
There is great public concern, often based on anecdotal reports, about risks from ionising radiation. Recent interest has been directed at an excess of leukaemia cases in the locality of civil nuclear installations at Sellafield and Sizewell, and epidemiologists have a duty to pursue such information vigorously. This paper sets out to show that the epidemiol

12. Socioeconomic studies of high-level nuclear waste disposal.
The socioeconomic investigations of possible impacts of the proposed repository for high-level nuclear waste at Yucca Mountain, Nevada, have been unprecedented in several respects. They bear on the public decision that sooner or later will be made as to where and how to dispose permanently of the waste presently at military weapons installations and that con
