An import licence alone does not let you use or store the source
Article 56.1 of the Law on Atomic Energy 94/2025/QH15 requires everyone conducting the radiation work listed in Article 14 to hold a radiation-work licence, and Article 14.3 spells out “using and storing radioactive sources”. That licence comes from the Agency for Radiation and Nuclear Safety (Ministry of Science and Technology) — a different authority, dossier and time limit from the Drug Administration’s import licence. And for the licensed shipment itself, Article 60.4 of the Law on Pharmacy caps it: “export and import may not exceed the quantity stated in the licence”.
