The Samut Prakan Radiation Accident

An Improper chain of custody of radiotherapy units can lead to an orphan source, where radioactive elements are knowingly or more commonly unknowingly removed from their protective enclosures.

An incident in Samut Prakan, Thailand in 2000 shows the importance of the correct handling, sale and disposal of radioactive elements. The event would result with 3 dead and over 1800 exposed.
