Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area dedicated for radioactive materials. Due to its hygroscopic and strong oxidizer properties, the container must be kept sealed in a controlled atmosphere (e.g., dry inert gas or desiccator) when not in use to prevent moisture absorption and decomposition. Adhere to all local, national, and international regulations for the storage of radioactive substances.
