Quality Control

Our Neptunium-237 is produced and handled under strict quality protocols to ensure isotopic purity and radionuclidic consistency. Each batch is characterized using high-resolution gamma spectrometry and α-particle spectrometry to confirm identity and assay. Certificates of Analysis (COA) detailing isotopic composition, specific activity, and radiochemical purity are provided. Production and handling adhere to relevant nuclear material control and safety regulations.

Storage

Preserve in a tightly closed container, protected from light. Due to its radioactive nature and sensitivity to oxidation, store under an inert atmosphere in a dedicated, shielded facility designed for α-emitting radionuclides. Maintain storage areas at controlled room temperature (15-25°C) with appropriate monitoring for radiation safety and containment integrity. Comply with all local, national, and international regulations for radioactive material storage.
