Book (stand-alone)Data management and visualisation in response to large-scale nuclear emergencies affecting food and agriculture 2019
Also available in:
No results found.In a large-scale nuclear emergency affecting food and agriculture, the release of radionuclides to the environment can severely impact the food chain and human health. Up-to-date information of soil, water and crops are pertinent to informing decisions that prevent potentially contaminated products from reaching consumers. However, traditional management and visualisation of data are constrained in response times and decision-making accuracy as they are often not centralized and performed manually. Developments in information technology (IT) allow for Decision Support System (DSS) tools and algorithms to enhance real-time management of large volumes of data and decision-making in a spatio-temporal context. These IT support functions increase the capacity of stakeholders to focus on the most important matters at hand – ensuring food and consumer safety. This publication presents the challenges and solutions of real-time data management, geo-visualisation and decision making, as well as two case-studies of how innovative IT systems can assist in nuclear emergency response affecting food and agriculture. One of the case studies presented is by the Soil and Water Management and Crop Nutrition Laboratory of the Joint FAO/IAEA Division; the other case study by Japanese Competent Authorities in the aftermath of the Fukushima Daiichi Nuclear Power Plant accident. -
Brochure, flyer, fact-sheetNuclear Accidents and Radioactive Contamination of Foods
INFOSAN - 30 March 2011
2011Also available in:
No results found.Radioactive isotopes of elements (radionuclides) are naturally present in the environment, and that includes our bodies and our food and water. We are exposed to radiation (also known as background radiation) from these radionuclides on a daily basis. Radiation comes from space (i.e., cosmic rays) as well as from naturally-occurring radioactive materials (radionuclides) found in the soil, water and air. Radioactivity can be detected in food and water and the concentration of naturally-occurring radionuclides varies depending on several factors such as local geology, climate and agricultural practices. -
Book (stand-alone)Use of 137Cs for soil erosion assessment 2017
Also available in:
No results found.Soil erosion is the most destructive land degradation process causing removal of soil, siltation of water reservoirs and pollution of water sources. Combating erosion needs reliable data on soil erosion rates, its dynamics and spatial distribution. Collecting such data with conventional methods requires great investment and long period of time. The 137Cs method for erosion assessment can address this problem. The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture of the IAEA h as been working on this method for more than 20 years. This publication provides a brief guidance on this method. It covers major components of 137Cs method starting from its principles, the sampling strategy, gamma spectroscopic measurements, estimation of erosion rates with conversion models, data interpretation and the use of 137Cs method for erosion models validation. The publication is suitable for a wide audience such as researchers, agricultural and environmental experts, decision makers, farmers and students.
