1. Monitoring reinforcement corrosion of concretes designed for nuclear facilitie
ABSTRACT The facilities designed for the peaceful activities of nuclear energy are made with different materials, among them, reinforced concrete. This material, in addition to being structural, is a barrier for isolation and confinement from the environment of the radioactive materials. One of its degradation mechanisms is the corrosion of the reinforcement

2. Aging simulation of the tailings from Stava fluorite extraction by exposure to gamma rays
Abstract Tailings storage facilities are disposal systems for storing the waste products of the mining industry consisting of a slurry mixture made of soil, rock and water that remain after the mineral values have been removed from the patent ore. Tailings dams are supposed to last forever, so after their deposition, tailings can experience aging processes w

3. Impact of an Alkaline Solution on the Chemistry, Mineralogy, and Sorption Properties of a Typic Rhodudult Soil
Abstract The preferred option for disposal of short-lived low and intermediate level radioactive wastes is a near surface disposal facility in which soil is one of the barriers that avoid radionuclide migration outside the controlled area. For construction of that kind of facility, concrete is widely used, and its interaction with water induces its degradati

4. Sistema de gestão integrada de dados para repositórios de rejeitos radioativos (SGI3R)
A implantação de um repositório para rejeitos radioativos é um projeto multidisciplinar que demanda além de especialistas de diferentes áreas do conhecimento, a interação com instituições públicas e privadas, dados e informações relacionadas com rejeitos radioativos, geologia, tecnologia etc. Todas as atividades devem estar em conformidade com a

5. Gestão de rejeitos radioativos em serviços de medicina nuclear / Gestão de rejeitos radioativos em serviços de medicina nuclear
Radioisotope applications in nuclear medicine services, for diagnosis and therapy, generate radioactive wastes. The general characteristics and the amount of wastes that are generated in each facility are function of the number of patients treated, the procedures adopted, and the radioisotopes used. The management of these wastes embraces every technical and

6. Estudo de sorção de césio e estrôncio em argilas nacionais para sua utilização como barreira em repositórios de rejeitos radioativos / Study of cesium and strontium sorption in brazilian clays for their use as a barrier in repositories of radioactive wastes
Wastes in general should be properly treated and stored. Then the radioactive wastes also rquire suitable and safe management beginning in their generation until the storage in repository. The main purpose of the radioactive waste management is to preserve the human beings and the environment. The objective of this research ws to characterize some brasilian

7. Implementação de um sistema unificado para gerenciamento de rejeitos / Implementation of a unified system to waste management
The process of generation and disposal of wastes has been responsible for many economical, ecological and public health problems, although the importance of its safe management for the protection of human health and the environment has long been recognized. In order to manage the hazardous wastes in an environmentally-friendly manner, many technical and admi

8. O gerenciamento dos resíduos dos serviços de saúde de uma amostra de hospitais nacionais
This document is the Final Report of a research project sponsored by the Center of Research and Publications from the Getulio Vargas Foundation São Paulo Business School. The Report analyzes the Health Care Wastes Management Plans written by 70 Brazilian hospitals after being trained in a course offered by the Santa Catarina State Federal University and the

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

10. DISPOSAL OF RADIOACTIVE WASTE: A STUDY OF AN ALTERNATIVE / DESCARTE DE REJEITOS RADIOATIVOS: ESTUDO DE UMA ALTERNATIVA
Resolving the high-level waste disposal question is one of the most serious problemas facing the nuclear industry today. To guarantee that nuclear waste never reaches the biosphere, researchers in several laboratories are devising a multiple-barriers concept, to prevent groundwater and corrosion from disturbing the waste disposal site. First, the waste is fu

12. Microbial activity of trench leachates from shallow-land, low-level radioactive waste disposal sites.
Trench leachate samples collected anoxically from shallow-land, low-level radioactive waste disposal sites were analyzed for total aerobic and anaerobic populations, sulfate reducers, denitrifiers, and methanogens. Among the several aerobic and anaerobic bacteria isolated, only Bacillus sp., Pseudomonas sp., Citrobacter sp., and Clostridium sp. were identifi
