Description

Actinium is a rare, silvery-white radioactive metal belonging to the actinide series. Its unique radioactive properties make it a critical material for specialized scientific and industrial applications, particularly as a potent α-particle source. This element is essential for researchers and manufacturers in the nuclear technology, targeted alpha therapy (TAT), and neutron source sectors who require high-purity radioactive materials.

Application

• Targeted Alpha Therapy (TAT): As a powerful alpha emitter, Actinium-225 is a key isotope in advanced radiopharmaceuticals for cancer treatment, specifically for targeting and destroying microscopic cancer cells.
• Neutron Source Production: Used in the generation of neutrons for research purposes, including neutron scattering experiments and as a starter for certain types of reactors.
• Radioisotope Thermoelectric Generators (RTGs): Serves as a heat source in RTGs for space missions and remote terrestrial applications due to its high specific activity.
• Scientific Research: Employed in fundamental chemistry and physics research to study the properties of heavy elements and radioactive decay chains.
• Industrial Gauging: Utilized in devices that measure thickness, density, or level in industrial processes where intense radiation is required.

Quality Control

Our Actinium products are produced and handled under strict quality management systems to ensure isotopic purity, radionuclidic purity, and chemical consistency. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing specific activity, radionuclidic identity, and chemical impurities. We adhere to relevant guidelines for the handling of radioactive materials to ensure product integrity and safety.

Storage

Preserve in a tightly closed container, protected from light. Due to its radioactive and easily oxidized nature, it must be stored under an inert atmosphere (e.g., argon) in a designated, secure, and licensed facility for radioactive materials. Store at controlled room temperature (15-25°C) in a dry, well-ventilated area away from incompatible materials.
