Mapeamento de fontes radioativas na indústria brasileira

Abstract

Due to major accidents as the one that happened in Goiânia (Caesiun-137), portion of the population only knows the ionizing radiation negative effects. However, the use of radiation for human kind well-being, sometimes, goes through unnoticed. In the general industry, the use of radioactive ionization is present in process control, measurements, inspections, radiographs, analytical techniques and tracers. The main goal of this work is to map radioactive sources in the national industries. To accomplish the mapping, facilities that are authorized to use ionizing radiation were analyzed. Public information regarding these facilities maybe be accessed in CNEC (national) website and in the IEAE (worldwide) files directories. The facilities were divided in groups according to source type application. The lack of new reactors for production and research for industrial and medicine purposes was the result of this mapping. It was observed that in 2018 there is 662 authorized facilities, they are concentrated in SP, MG, RJ, PR, BH and RS, states of Brazil. During the mapping it was found out that the regions with the highest number of authorized facilities the ones that own nuclear reactors: SP, MG and RJ, Brazil.
