Description

Radium is a highly radioactive alkaline earth metal, historically significant for its luminescent and therapeutic properties. Its intense radioactivity makes it a critical material for specialized industrial and research applications where controlled radiation sources are required. This product is essential for sectors including nuclear research, industrial radiography, and the production of self-luminous paints and neutron sources.

Application

As a neutron source when mixed with beryllium for well logging and reactor start-up in the nuclear industry.
In the manufacture of self-luminous paints for watch dials, aircraft instruments, and emergency signage (historical and limited modern use).
For industrial radiography to inspect metal castings and welds for flaws.
As a calibration source for radiation detection and measurement equipment.
In scientific research for studying radioactive decay chains and alpha particle emission.
For medical applications in brachytherapy for cancer treatment (largely historical, superseded by safer isotopes).

Quality Control

Our Radium products are handled and supplied in full compliance with stringent international nuclear safety and security regulations. Each batch is accompanied by complete documentation detailing its radioactive characteristics, including specific activity and isotopic purity. Certificates of Analysis (COA) and material safety data are available upon request to ensure traceability and regulatory adherence for our global clientele.

Storage

Preserve in a tightly closed, specially shielded container, protected from light and stored under an inert atmosphere. Due to its radioactive and easily oxidized nature, it must be stored in a dedicated, secure, and ventilated facility designed for radioactive materials. Strict temperature and humidity controls are required as per nuclear material handling protocols. Access is restricted to authorized personnel only.
