The safety and security of radioactive sources is a central challenge in global nuclear governance, as growing reliance on such materials in industry, medicine and research raises the risk of unauthorized access, theft or malicious use. Regulatory bodies, operators and other stakeholders are under pressure to maintain control of radioactive material throughout its entire life cycle.
A national system for controlling radioactive sources is the foundation of efforts to prevent loss, theft or misuse. Such a system covers the full path from acquisition to disposal and defines the responsibilities of every party involved. A core regulatory framework typically includes the following elements:
These controls are intended to establish clear accountability and to make the movement and use of radioactive sources traceable. Effective oversight depends on consistent application across all licensed facilities.
The safe management of radioactive sources is not a single checkpoint but a continuous process spanning the entire life cycle. Each stage, from acquisition and use to storage and final disposal, carries potential safety and security risks.
| Management stage | Key control point | Objective |
|---|---|---|
| Acquisition and authorization | License review, qualification verification | Ensure traceability of source flows |
| Operation and use | Safety assessment, personnel training | Prevent operational errors and violations |
| Security protection | Theft prevention, protection against malicious tampering | Resist illegal intrusion and malicious acts |
| Waste management | Recovery, long-term safe disposal | Eliminate environmental risks from disused sources |
Lifecycle controls require operators to maintain security measures at every stage and to ensure that personnel are trained for the tasks they perform. Regulators monitor compliance through inspections and licensing conditions.
Even with preventive measures in place, emergency response capacity remains critical. This includes rapid response mechanisms for cases in which radioactive material is lost, stolen or illegally disposed of.
Security of radioactive material also has a global dimension. International cooperation and information sharing are indispensable for raising security standards worldwide. By exchanging best practices and intelligence, countries can coordinate more effectively against cross-border threats involving radioactive material.
