Quality Control

Our Berkelium is produced and handled under stringent, controlled conditions to ensure isotopic purity and chemical integrity. All materials are subject to rigorous analytical verification, including mass spectrometry and gamma spectroscopy, to confirm isotopic composition and radionuclidic purity. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting specific activity, isotopic distribution, and chemical form.

Storage

Preserve in a tightly closed container, protected from light. Due to its radioactive nature and property of being easily oxidized, this material must be stored under an inert atmosphere (e.g., argon) in a designated, secure, and licensed radioactive materials facility. Storage must comply with all applicable national and international regulations for the handling and containment of α-emitting radionuclides.
