The government is looking to buy radiation detection equipment (RDE) to deter and detect illicit trafficking of radioactive materials across international borders. Border crossings, integrated check posts (ICPs) and land ports will be equipped with RDE to stop any smuggling of material needed for a nuclear device or radiological dispersal device, said officials.India's premier defence research institute DRDO has identified 108 military systems and subsystems like navigation radars, tank transporters and missile canisters for the domestic industry to design, develop and manufacture.
The basic principle behind this instrument is the use of a special material which glows or "scintillates" when radiation interacts with it. The most common type of material is a type of salt called sodium-iodide. The light produced from the scintillation process is reflected through a clear window where it interacts with device called a photomultiplier tube. The first part of the photomultiplier tube is made of another special material called a photocathode.
