Description

Fermium is a synthetic, radioactive actinide metal with the atomic number 100, known for its significant role in advanced nuclear research and specialized scientific applications. Its primary value lies in its utility as a neutron source and target material for the synthesis of heavier transuranium elements, enabling critical studies in nuclear physics and chemistry. This high-purity material is essential for dedicated research institutions, government nuclear laboratories, and facilities involved in fundamental particle research and the development of nuclear technologies.

Application

• Nuclear Research & Synthesis: Used as a target material in particle accelerators and heavy-ion reactors for the production of heavier elements (e.g., mendelevium, nobelium).
• Neutron Source: Serves as a compact and potent neutron emitter for specialized activation analysis and radiation physics experiments.
• Fundamental Science Studies: Critical for investigating the chemical and physical properties of the actinide series, including redox behavior and metallurgy under controlled conditions.
• Radioisotope Thermoelectric Generators (RTGs): Potential application as a heat source in long-lived, compact power systems for deep-space missions, subject to advanced development.
• Educational Reference Standards: Provides traceable radioactive standards for calibrating detection equipment and training in nuclear science.

Quality Control

Our Fermium products are produced and handled under stringent, controlled environments to ensure isotopic purity and radiological safety. All materials are subject to rigorous analytical verification, including mass spectrometry for isotopic assay and gamma spectroscopy for radionuclidic purity. A comprehensive Certificate of Analysis (COA) detailing specific activity, isotopic composition, and impurity profiles is provided with each shipment to ensure traceability and compliance with research-grade specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its radioactive nature and potential for radiolytic decomposition, material must be stored in dedicated, shielded facilities compliant with all national and international regulations for radioactive materials (e.g., IAEA standards). Store under an inert atmosphere to minimize oxidation. Temperature should be maintained at a stable ambient range (15-25°C). Access is restricted to authorized personnel only.
