Current developments in many parts of the world still suggest that movements of radioactive material beyond regulatory and law enforcement authorities’ control continue.
Such movements may be either intentional or unintentional.
Intentional, illicit movement of radioactive material, including nuclear one, for terrorist, political purposes, or to obtain illegal profits is generally regarded as unlawful trafficking.
Most often, movements outside the regulatory control are unintentional.
An example of unintentional movement may be the transportation of steel contaminated by a molten radiation source, the proper control of which had been lost.
Such shipment may threaten the health and safety of the person concerned and the population in general.
Governments are responsible for combatting the illicit trafficking and unintentional movements of radioactive materials.
