Irradiação de alimentos: um estudo de caso

Abstract

Food irradiation has been increasingly used for food preservation, this is mainly due to increased product shelf life, facilitating the transport of perishable products. In addition to this benefit is the fact the food be preserved in its organoleptic characteristics. Lack of specific Regulatory Standards to high doses of radiation, the study object a study of standards proposed by the National Commission of Nuclear Energy (CNEN) has to be present, which is the body responsible for all matters relating to radiation in Brazil. For this study the methodology of case study developed by document analysis will be used. Among the groups proposed by the Commission, this study will consider the groups 3, 6, 7 and 8, because these groups are essential for the implementation of an industry of food irradiation. Group 3 mentions procedures for radiological protection. Group 6 with respect to industrial facility itself and the steps that must be taken to obtain a license for the installation and processing. Group 7 relates to certification of persons responsible for supervising and supporting the industrial plant. Finally the group 8 provides information on radioactive waste by providing information about the fate and the correct procedures. The doses of radiation are emitted and absorbed the basis for calculation of the distances to the radiation source that must be public, with the distance of 2 meters as a minimum placed, there is still the need to have a concrete wall with inner at least 5 cm of lead. Regarding PPE must wear appropriate gloves, goggles, duly closed shoes, protective clothing to use in identification in a places of irradiation. Is still necessary to make the monitoring of radiation received by reviewers and monitoring of radiation present in each area. Each area should have industrial classification and should be indicated at each location along with the procedures to be followed in case of emergency. It was possible to observe the lack of further study in this area, and this is highly necessary for the increase of this market.
