Description

Curium CAS NO 7440-51-9 is a synthetic, radioactive actinide metal, primarily produced in nuclear reactors. Its significance lies in its potent α-emitting properties, which are harnessed for specialized industrial and scientific applications. This material is essential for researchers and industries involved in neutron source production, radioisotope thermoelectric generators (RTGs), and advanced nuclear fuel cycle studies.

Application

• Neutron Source Production: Used in compact, portable neutron sources for oil well logging, moisture detection, and on-line elemental analysis.
• Radioisotope Thermoelectric Generators (RTGs): Serves as a long-lived heat source in power systems for deep-space probes and remote terrestrial installations.
• Nuclear Research: Acts as a target material for synthesizing heavier transuranium elements in particle accelerators.
• Spectroscopic Analysis: Employed as a calibrated α-particle source for detector calibration and fundamental physics research.
• Advanced Fuel Cycle Studies: Investigated for its behavior and potential applications in next-generation nuclear reactor systems.

Quality Control

Our curium products are produced and handled under strict quality assurance protocols in specialized facilities. Each batch is characterized for isotopic composition and radionuclidic purity using high-resolution gamma spectrometry and alpha spectroscopy. Certificates of Analysis (COA) detailing specific activity, isotopic distribution, and impurity profiles are provided to ensure compliance with research and industrial specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its radioactive nature and the property of being easily oxidized, curium must be stored under an inert atmosphere (e.g., argon) in a designated, secure radiological facility. Storage must comply with all local and international regulations for radioactive materials. The container should be kept at a controlled room temperature (15-25°C) in a dry, well-ventilated area.
