1. Evaluation of ionizing radiation as a risk factor for the incidence of breast cancer: long-term analysis after the cesium-137 accident in Goiânia, Brazil. An ecological study
ABSTRACT BACKGROUND: The largest radiological accident to occur in any urban area happened in Goiânia, Brazil, in 1987. OBJECTIVE: To evaluate the association between breast cancer incidence and ionizing radiation levels. DESIGN AND SETTING: Ecological study among residents of the city of Goiânia, Brazil. METHODS: The central region of Goiânia, wi

2. Reconstructive dosimetry for cutaneous radiation syndrome
According to the International Atomic Energy Agency (IAEA), a relatively significant number of radiological accidents have occurred in recent years mainly because of the practices referred to as potentially high-risk activities, such as radiotherapy, large irradiators and industrial radiography, especially in gammagraphy assays. In some instances, severe inj

4. Uso de ambientes virtuais para a simulação de acidentes radiológicos / Use of virtual environments to simulate radiological accidents
Em um ambiente virtual, construído com o uso de tecnologia computacional, encontram-se presentes entidades virtuais inseridas em um espaço tridimensional, que é utilizado para a simulação de processos críticos, como os acidentes radiológicos. A pronta detecção de um acidente radiológico e a determinação da sua possível extensão são fatores ess

5. The effect of radiotherapy on the prophylaxis of heterotopic ossification in patients with spinal cord injury / Efeito da radioterapia na profilaxia da ossificação heterotópica em pacientes com lesão medular traumática
The goal of this study was to evaluate the effect of radiotherapy on the prophylaxis of heterotopic ossification (HO) after spinal cord injury (SCI). Nineteen SCI patients were studied (15 men and four women). The mean age was 30.4 ± 10.8 years (range 19 to 58 years). The most frequent causes of lesion were traffic accident (42.1%), fall (26.3%), shot gun (

6. Development of a computacional model for calculations of absorved dose to organs and tissues of the human body in situations of accidental exposures / Desenvolvimento de um modelo computacional para cÃlculos de dose absorvida em ÃrgÃos e tecidos do corpo humano nas situaÃÃes de exposiÃÃes acidentais
Exposure to a radiation field may be of medical, environmental, occupational or accidental nature, but in all cases the main objective is the determination of the whole body absorbed dose or the distribution of absorbed dose to specific organs and tissues. In recent years, estimates of the radiation absorbed dose in the human body have become more accurate d

7. Radioecological investigations in Brazilian tropical plants
The accumulation and long term behavior of radiocesium in chili pepper trees (Capsicum fructescens) were studied. The trees to be analyzed had been cultivated at one of the sites where the Goiânia radiological accident occurred and one of them transplanted to another site with uncontaminated soil. The aim of this paper is to examine the decline of 137Cs as

8. 137Cs distribution in guava trees
This paper presents results of 137Cs concentration measured from a guava tree cultivated after the first decontamination work of one of the sites where the worst Brazilian radiological accident occurred. The present work aims to verify how the 137Cs is transported and distributed along the tropical trees. Bi-dimensional analyses of the radial distribution of
