Description

Americium-241 is a synthetic, radioactive transuranic element belonging to the actinide series. This isotope is a critical alpha particle source valued for its consistent and predictable decay properties. It is an essential material for specialized industrial, scientific, and security applications requiring a reliable, low-energy radiation source. Key users include manufacturers of analytical instrumentation, industrial gauges, and research institutions.

Application

• Ionization Source in Smoke Detectors: The primary commercial application, where its alpha radiation ionizes air to enable smoke particle detection.
• Industrial Gauging: Used in thickness, density, and level gauges for continuous process control in manufacturing (e.g., paper, metal, plastics).
• Neutron Source Production: Combined with beryllium to create portable neutron sources for well logging in oil exploration and material analysis.
• Spectroscopic Calibration: Serves as a calibration standard for alpha, gamma, and X-ray spectroscopy equipment.
• Research & Development: Utilized in nuclear physics research, material science studies, and as a target material for producing other transuranic elements.
• Static Elimination: Employed in specialized ionizers to neutralize static charge in sensitive electronic manufacturing environments.

Quality Control

Our Americium-241 is produced and handled under strict quality protocols to ensure isotopic purity, radiological safety, and chemical stability. Each batch is accompanied by comprehensive documentation, including a Certificate of Analysis (COA) detailing isotopic assay (via alpha spectrometry and gamma spectrometry), chemical purity, and specific activity. Our processes adhere to stringent nuclear material handling and transportation regulations (IAEA, national nuclear regulatory bodies).

Storage

Preserve in a tightly closed, specially designed container, protected from all light exposure. Store in a dedicated, secure, and licensed radioactive materials facility under an inert atmosphere to prevent oxidation. Maintain at a controlled room temperature (15-25°C). Strict compliance with all local, national, and international regulations for the storage of radioactive materials is mandatory.
