Description

Americium CAS NO 7440-35-9 is a synthetic, radioactive actinide metal, primarily known for its role as an alpha particle emitter. This element is of critical importance in specialized industrial and research applications where a reliable, long-lived alpha source is required. It is essential for manufacturers and research institutions in the nuclear technology, smoke detection, and analytical instrumentation sectors.

Application

• Ionization Smoke Detectors: The most common commercial application, where americium-241 is used as a stable ionization source to detect smoke particles.
• Neutron Sources: Used in combination with beryllium (Am-Be source) to generate neutrons for well logging in the oil and gas industry, material analysis, and research.
• Industrial Gauging: Employed in thickness, density, and level gauges for process control in manufacturing (e.g., glass, paper, metal sheets).
• Radioisotope Thermoelectric Generators (RTGs): Serves as a heat source in small-scale RTGs for space missions and remote terrestrial applications.
• Spectroscopic Analysis: Used as an excitation source in X-ray fluorescence (XRF) spectrometers for elemental analysis.
• Academic and Government Research: Utilized in nuclear physics studies, actinide chemistry research, and the development of new nuclear fuel cycles.
