    Communication about occupational exposure
    2019 - LEVY, DENISE S.; SORDI, GIAN M.A.A.; RODRIGUES, DEMERVAL L.; CARNEIRO, JANETE C.G.G.
    Brazil is the largest country of Latin America, with 8.5 million square kilometers divided into five regions with 3 time zones. In this large between-country distances, with plenty of radioactive facilities throughout the country, professional education and communication is a must and a challenge. This paper discusses a web-based project designed to provide effective communication about occupational exposure, linking geographically distant workers to high-quality reliable information. The web-based-project UNIPRORAD counts on concepts, definitions and theory about radiological protection based on both national and international standards, guidelines and recommendations. The content includes optimization, monitoring, potential exposure and communication on occupational risk agents in the workplace. Regarding potential exposures, it is essential to consider the concept of “risk” which, even among scientific community, seems to assume a great variety of meanings. Regarding risk agents in the workplace, it is necessary to discuss the identification and evaluation of the various risk agents (physical, chemical biological and ergonomic) addressing attention to their association to ionizing radiation. This article presentsthe authors' experience in the communication of radiological protection in Brazil, presenting global and specific issues on radiological protection, analyzing recommendations and discussing discrepancies among the several valid publications. It is our objective the dissemination of trustful updated communication, providing radioactive facilities relevant, accurate and understandable information. Finally, the article emphasizes the need to spread information wherever it is needed to inform as many people as possible, contributing to develop workers´ professional skills and to improve safety culture in workplace.

    Produção de energia elétrica a partir de fontes nucleares
    2015 - SANTOS, I.P.; LEVY, D.S.
    This study reports a pedagogical experiment in high school classes, in a private school in São Paulo. The purpose of this experiment was to put students in touch with topics related to electric power generation from radioactive sources This project was developed with emphasis on the content available in an educational online portal, the site www.radioatividades.com.br. The site has been created in order to disseminate knowledge to children, adolescents, parents and teachers about the peaceful use of nuclear energy. The portal content is free to access and use for educational purposes. The project had three stages: initial dynamics on the subject with students, working with research groups, conducting short courses in the portal "radioatividades" and a final evaluation, which consisted in seminars prepared by students themselves. The first stage aimed to verify the previous knowledge that students had on nuclear energy, raising common prejudices that usually appear. The second phase of the project aimed to demystify some concepts, such as the insecurity linked to the use of atomic energy. For this research there were used reliable sources, as the site of the National Nuclear Energy Commission (CNEN), Institute of Radiation Protection and Dosimetry (IRD) and International Atomic Energy Agency (IAEA), as well as short courses offered by the portal "Radioatividades". To finish the project, the students formed groups and presented seminars for their classmates, with split topics, illustrative slides and post presentation time to answer questions. There were highly satisfactory results at the end of the project, performances with good theoretical foundation and valuable clarifications on nuclear energy.

    Food irradiation
    2019 - LEVY, DENISE S.; VILLAVICENCIO, ANNA L.C.H.
    Brazil is a major food producer and food exporter. Still, a large part of the Brazilian population faces hunger, food insecurity and malnutrition. From agriculture to the consumer's table, a significant part of the production is lost during post-harvest, transport, storage and commerce, due to the deterioration of food products. These are some of the main Brazilian issues and nuclear techniques present alternatives to this demand. Nevertheless, Brazilian consumers fear ionizing radiation and misunderstand its real benefits. Consumers do not know the difference between irradiated food and radioactive food and the public has major concerns about the negative health effects and environmental contamination. This article brings the authors' experience on science communication about Food Irradiation to teach fundamental concepts and answer to the most Frequently Asked Questions about processes, safety, advantages, limitations, possibilities, impacts on human health and impacts on the environment. The content includes global aspects of food irradiation, laws and regulations, nuclear techniques in agriculture and the potential value of nuclear technology to contribute to national economy and public health. This paper describes the different tools used for outreach different audiences, to assist other experts on planning strategies to communicate nuclear science. Food irradiation improves the quality of daily life, but it is not enough to have innovation and technology if there is no information. Scientific community is expected to communicate science outside academia, informing the public and qualifying opinion-makers. It is a must to educate future problem solvers and actual decision-makers, including producers, industry, commerce and consumers.

    Educating the educators
    2019 - LEVY, DENISE; VILLAVICENCIO, ANNA L.C.H.
    In a rapid-changing world, science teachers face considerable challenges. In addition to the basic curriculum, there must be included several transversal themes, which demand creative and innovative strategies to be arranged and integrated to traditional disciplines. In Brazil, nuclear science is still a controversial theme, and teachers themselves seem to be unaware of the issue, most often perpetuating prejudice, errors and misconceptions. This article presents the authors’ experience in the development of an interdisciplinary pedagogical proposal to include nuclear science in the basic curriculum, in a transversal and integrating way. The methodology applied was based on the analysis of several normative documents that define the requirements of essential learning, competences and skills of basic education for all schools in Brazil. The didactic materials and resources were developed according to the best practices to improve learning processes privileging constructivist educational techniques, with emphasis on active learning process, collaborative learning and learning through research. The material consists of an illustrated book for students, a book for teachers and a manual with activities that can articulate nuclear science to different disciplines: Portuguese, mathematics, science, art, English, history and geography. The content counts on high scientific rigor and articulate nuclear technology with topics of interest to society in the most diverse spheres, such as food supply, public health, food safety and foreign trade. Moreover, this pedagogical proposal takes advantage of the potential value of digital technologies, implementing QR codes that excite and challenge students of all ages, improving interaction and engagement. The expected results include the education of the educators for nuclear science communication in a transversal and integrating way, demystifying nuclear technology in a contextualized and significant approach. It is expected that the interdisciplinary pedagogical proposal contributes to improving attitudes towards knowledge construction, privileging reconstructive questioning, fostering a culture of systematic curiosity and encouraging critical thinking skills.

    Education and citizenship
    2017 - LEVY, DENISE; PERALTA, TELMA M.; POZZI, LORENY; TOVAR, IZI P. de; SANTOS, IGOR P. dos; VILLAVICENCIO, ANNA L.C.H.
    In the so-called Information Society, knowledge is a powerful tool for real social inclusion. Inclusion through knowledge is a citizen attitude, as it changes students’ perceptions, allowing critical thinking, stimulating the ability to question the world and encouraging to change reality as active citizens. Popularization of science is a must and a challenge. In a globalized world where the Internet seems to be the largest vehicle for information, offering children and young people the illusion of unlimited knowledge, the traditional academic practices do not seem to correspond to the student's desire of learning. Under the light of psycho-pedagogical perspective, we can discuss different possibilities to communicate science in the academic context, at different ages, from pre-school to university. This article brings together the experience of six educational professionals who use the psycho-pedagogical know-how to promote a meaningful and interesting learning. Psycho-pedagogical practices consider the singularity of each group, students protagonists in learning process, stimulating reconstructive questions, re-signifying previous knowledge, making knowledge meaningful and relevant, thus articulating student´s desire to the scientific discourse.

    Web-based tools to increase public understanding of nuclear technology and food irradiation
    2017 - LEVY, DENISE; VILLAVICENCIO, ANNA L.C.H.
    Food irradiation is a processing and preservation technique to eliminate insects and parasites and reduce diseasecausing microorganisms. Moreover, the process helps to inhibit sprouting and delay ripening, extending fresh fruits and vegetables shelf-life. Nevertheless, most Brazilian consumers seem to misunderstand the difference between irradiated food and radioactive food and the general public has major concerns about the negative health effects and environmental contamination. Society´s judgment and decision making are directly linked to perceived benefits and risks. The web-based project entitled ‘Scientific information about food irradiation: Internet as a tool to approach science and society’ was created by the Nuclear and Energetic Research Institute (IPEN), in order to offer an interdisciplinary approach to science education, integrating economic, ethical, social and political aspects of food irradiation. This project takes into account that, misinformation and unfounded preconceived ideas impact heavily on the acceptance of irradiated food and purchase intention by the Brazilian consumer. Taking advantage of the potential value of the Internet to enhance communication and education among general public, a research study was carried out regarding the possibilities and trends of Information and Communication Technologies among the Brazilian population. The content includes concepts, definitions and Frequently Asked Questions (FAQ) about processes, safety, advantages, limitations and the possibilities of food irradiation, including health issues, as well as its impacts on the environment. The project counts on eight selfinstructional interactive web courses, situating scientific content in relevant social contexts in order to encourage self-learning and further reflections. Communication is a must to improve public understanding of science. The use of information technology for quality scientific divulgation shall contribute greatly to provide information throughout the country, spreading information to as many people as possible, minimizing geographic distances and stimulating communication and development.
