environment and tendencies based on the current results

The purpose of this project was to analyze the individual doses of occupationally exposed in-
dividual resulting from changes in the reactor operation regime. Optimizations studies were
carried out at the reactor facility as well as radioprotection procedures were adopted aiming
at the safety and the goal of reaching acceptable dose of workers.

Policy evolution of the dose limitation system and the issue
of replacements in the “superseded” publications

The study aimed to present a careful analysis about the policy evolution of the dose limitation
system based on two entities, the International Commission on Radiological Protection pub-
lications and International Atomic Energy Agency recommendations. Through this research,
from the 50´s to present day, it was possible to clear and detail valuable information that was
lost during the process of updating publications and editing recommendations of both entities.

The flexibility of competence and regulatory process
regarding safety and radiation protection

The use and increasingly application of consistent nuclear technology in areas related to health,
energy, industrial, war, agriculture, among others, means that there is a need for regulation in
accordance with the safety standards and international radiological protection. Using concepts
from the Constitutional, Environmental and Labor Laws, the focus of this research was to inves-
tigate the difficult issue of nuclear competence and environmental responsibility, the impossi-
bility of legislating states, as well as, the lack of regulation on radioactive waste in our country.

Virtual environment for information and communication: online
system about the CNEN´s radiological protection plan

This research is premised on responding to the emergence of the need for dissemination of in-
formation to radioactive facilities in the field of radiological protection. The work involves the
development of an integrated system for the computerization of the CNEN´s Radiological Pro-
tection Plan, contemplating the several items required in the RPP (Radiological Protection Plan)
and REP (Radiological Emergency Plan), regarding potential exposures, seeking CNEN nation-
al standards and the international recommendations of the ICRP and the IAEA. This subject is
currently the main field of radiological protection research. Information and Communication
Technologies (ICT´s) will enable a quantitative and qualitative increase of available informa-
tion, contributing to the sustainability of the decision-making process and strengthening of
radiological protection throughout the National Territory.

Products and services

The main objective of the Radioprotection Service is to provide IPEN workers and the gener-
al public adequate protection against ionizing radiation. Adequate procedures and monitor-
