Overview
- CNEN and Ipen say detectors flagged traces of technetium‑99 in the Centro de Radiofarmácia and that two operators had superficial contamination of clothing that was decontaminated.
- Both workers underwent whole‑body counts that showed no internal contamination and CNEN reports no health effects and that the staff received retraining.
- The occurrence was recorded in an internal report and was sent to the Autoridade Nacional de Segurança Nuclear, which confirmed a technical investigation is under way.
- ANSN issued a regulatory notification requiring Ipen to provide verification documents by June 18 as investigators review procedures and measurements.
- Worker unions say decontamination included retention of clothing and some actions in areas not equipped for radiological care, and they warn that staffing, budget cuts and delayed medical exams at Ipen could affect safety and supply of radio‑pharmaceuticals to hundreds of clinics.
