Following its Safety, Environment and Health Policy, IEN maintains an Environmental Monitoring Program, a Radioactive Waste Management Program, a Radiological Protection Plan and an Emergency Plan. Accordingly, the Institute ensures that the Radiological Protection Service controls the processes involving radioactive materials.

The environmental dosimetry of gamma radiation is carried out using thermoluminescent dosimeters (TLD). For this procedure, 22 TLD detectors, evaluated every three months, are installed in the grounds of the Institute. The measurements attest to no environmental impacts due to ionizing radiation.

The effluent gases from the radiopharmaceutical production process pass through special filters, which are evaluated by gamma spectrometry to ensure that the atmospheric emissions do not present radioactive indices higher than the ones recommended in the norms. The effluent liquids, likewise, are monitored in decaying tanks, ensuring that the liberated emissions are always within the recommended levels.
