   Radiation Protection Centre (hereafter – RSC) recorded, investigated and evaluated 35 radiological incidents occurred in Lithuania in 2019 (see Figure 1).

   Most of recorded radiological incidents were detained cargoes emitting increased ionizing radiation (wood fuel contaminated with 137Cs, building materials etc.).

   Three radiological incidents related to the unjustified exposure of patients in health care institutions of Lithuania were investigated: computed tomography procedure was performed on a wrong patient, inadequate scans for diagnosis were received because of a failure of the system for administration of radiopharmaceuticals and a fetus was exposed because the patient undergoing radiological procedures did not know that she was pregnant.

Distribution of radiological incidents registered

 

   A case was investigated when after a bus scan by a stationary X-ray control system at a border checkpoint one person was found. A conservative assessment revealed that exposure which person could have been exposed did not exceed the dose limits per scan of 10 μSv established for individual exposure from non-medical imaging.

Detected orphan radioactive sources and objects with radioactive contamination

 

   Seven cases of detected orphan radioactive sources and five objects with radioactive contamination were investigated (smoke detectors containing 241Am and 239Pu radionuclides, an anti-frost detector with 90Sr/90Y radionuclide, metal scrap contaminated with 226Ra and 232Th radionuclides etc.). Orphan radioactive sources and objects with radioactive contamination were transferred to the radioactive waste manager to be disposed as radioactive waste in accordance to the requirements of legislation.

   In the prevention of radiological incidents, RSC focused on a training of the first responders, more than 170 persons were trained on radiation protection.

   RSC cooperated in the organization and participated in a state level full-scale exercise “Actions of Civil Protection System Institutions in the Event of the Explosion of a Dirty Bomb with Radioactive Materials at the Mass Gathering Place”. During the exercise, RSC provided recommendations on radiation protection to the first responders, who work in an area potentially contaminated with radioactive materials, proposed protective measures to the public, adjusted the perimeter of the internal protection zone, assessed the radioactive contamination of victims and the site and ensured quality control of decontamination.


   RSC participated in the ECUREX-2019 emergency preparedness exercise organized by the European Commission, which aimed to test the ability of the EU and other countries participating in the ECURIE emergency information exchange system to exchange information on nuclear and radiological accidents in a timely manner.
