Quality Control

All materials are handled and characterized under strict, controlled environments to ensure isotopic purity and radiological safety. Production and analysis follow stringent protocols aligned with nuclear material handling standards. A comprehensive Certificate of Analysis (COA) detailing isotopic composition, radionuclidic purity, and specific activity is provided with each shipment to meet the exacting requirements of research and regulatory compliance.

Storage

Preserve in a tightly closed container, protected from light. Due to its radioactive nature, material must be stored in dedicated, shielded facilities (e.g., lead or depleted uranium containers) designed for α-emitting radionuclides. Storage areas must comply with all national and international regulations for radioactive materials (IAEA, NRC, etc.). Maintain records of inventory and radiation monitoring as required by law.
