[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] The IAN has an administrative and juridical staff that carry out the administrative work needed by the Institution and take care of the law completion

[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] 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] The rapid technical development of Colombia over the past years, resulted among others, a considerable increase in the number of measuring instrumentation and testing laboratories, scientific research and metrology centers, in industry, agriculture, public health, education on the nuclear field, etc. IAN is a well organized institution with qualified management, trained staff and reasonably equipped laboratories to carry out tasks as: Metrology, standardization, quality control and maintenance and repair of nuclear instruments. The government of Colombia has adopted a policy to establish and operate through the country maintenance and repair facilities for nuclear instrumentation. This policy is reflected in the organization of electronic laboratories in Bogota-IAN

[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] 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] 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

[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
