[en] On the thirtieth anniversary celebration of the ''Instituto de Asuntos Nucleares'', a historical review of its activities has been made, emphasizing on its politics of development, technological and scientific advances, including the goals and accomplishments attained for the uses and applications of nuclear technology in Colombia. This includes the technical assistance which is being provided by International Organizations. National and international influences are shown for each one of the technical areas: agricultural applications, industrial applications and metallurgy, biochemistry and radiopharmacy, development process, nuclear electronics, solar and non-conventional energies, gamma facility, nuclear physics, hydrology, raw materials, chemistry, health radiophysics, reactor, nuclear documentation and information center and administration

[en] The article reviews the historical development of the nuclear medicine in Colombia and the primordial role of the IAN in this field. The main objective of the Biochemistry and Radiopharmacy Area is go to give technical support for the application of the nuclear energy in the human and veterinary medicine. The department has laboratories for the production of radiopharmaceuticals to be labelled with Tc-99m and quality control of the same human and veterinary RIA. Each one of the laboratories develops its work in three different areas: research and development, production, training and teaching. An actualization of the programs, results and publications are analyzed in this review also. Some of these programs have the support of the IAEA

[en] This article emphasizes the importance of the program on radiation protection; making a historical review since the creation of IAN. Its objectives, functions and development in the different sections, and its present and future perspectives are presented

[en] Process development: The paper describes the organization and laboratory facilities of the group working on radioactive ore processing studies. Contains a review of the carried research and the plans for the next future. A list of the published reports is also presented

[en] A brief description of the radiological applications available with high intensity radiation sources is made, preceded by a short historical review of the gamma irradiation plant of the Instituto de Asuntos Nucleares. The most important researches carried out, the services given to industry, hospitals, universities and infrastructure are mentioned. Finally, some of the publications realized in the last years are summarized

[en] From 1961 the use of nuclear energy in the industrial field in Colombia has a big advance. Today nuclear isotopes are used by private companies in this kind of application the Area of Industrial Applications and Metallurgy was the institution section that has trained and has transferred the technology needed for this purpose

[en] Short history of the ''Instituto de Asuntos Nucleares''. A short historical review about IAN is made: from 1956 when it was called Instituto Colombiano de Asuntos Nucleares, showing its scientific and technical development and the most important events that have occurred in the last 30 years. The people who had contributed to the progress of the institution are also considered, making emphasis in the important happenings that have guided the routes of the IAN

[en] A historical review of the evolution of the Nuclear Physics Section at the IAN is presented along the 30 years of existence of the Institute. Objectives, structure, programs and goal are historically examined. Present status of the section and its projection on national development is also analyzed

[en] Isotopical techniques are used in hydrology area for exploration, evaluation and exploration of water investigation. These techniques have been used successfully and are often the best or only means for providing certain hydrogeological parameters

[en] Since its beginnings, the Agricultural Area had a selected research team involved in the development of different agricultural techniques. Currently, there are two main branches engaged in the solution of agricultural problems: Soil fertility and induced mutations. Soil fertility: Within this branch, studies on soil nutrients and availability of water and light resources, have been made by using isotope methods. In the near future studies on nitrogen and potassium content in potato, rice and wheat plantations will be held. Induced mutations: The main objective of this team is to obtain through radioinduced mutations, as well as in vitro growth, improved rice and other cereal seeds to be used under hostile environmental conditions. The further goal will be to develop new genotypes straight from the mutants or by utilization of this material as breeding materials in interchange programs
