Description

Radium-226 is a naturally occurring radioactive isotope of the alkaline earth metal radium, identified by CAS NO 13982-63-3. It is a critical α-emitting source valued for its high specific activity and historical significance in radiation science and industrial applications. This material is essential for specialized research, industrial radiography, and as a neutron source precursor in sectors including nuclear technology, scientific instrumentation, and non-destructive testing.

Application

• Industrial Radiography: Used as a sealed source for inspecting metal castings and welds in non-destructive testing (NDT).
• Neutron Source Production: Mixed with beryllium to create compact, portable neutron sources for well logging and research.
• Scientific and Calibration Standards: Serves as a reference standard for calibrating radiation detection and measurement equipment.
• Historical and Educational Use: Employed in controlled settings for demonstrating principles of radioactivity and nuclear physics.
• Luminous Paints (Legacy Applications): Historically used in self-luminous paints for watch dials and aircraft instruments.
• Medical Therapy (Historical): Was used in early forms of brachytherapy for cancer treatment.

Quality Control

Our Radium-226 is produced and handled under strict quality assurance protocols in compliance with international nuclear safety and transportation regulations (IAEA, ISO 2919). Each batch is accompanied by comprehensive documentation detailing isotopic purity, specific activity, and radionuclidic impurities. Certificates of Analysis (COA) and Material Safety Data Sheets (MSDS) compliant with global standards (REACH, OSHA) are provided.

Storage

Preserve in a tightly closed, specially designed and approved container, protected from all light exposure and stored under an inert atmosphere to prevent oxidation. Store in a dedicated, secure, and shielded radioactive materials facility at a controlled ambient temperature (15-25°C). Strictly adhere to all local, national, and international regulations (IAEA, NRC) for the storage and handling of radioactive substances.
