Radiation has optimized a number of process in the plastics industry. Infrared emitters are the devices that uses radiation which are used in the said industry. These are devices which could be adjusted precisely depending on the product and the process. These emitters can make plastics welding within seconds. And since they can be adjusted precisely, it saves a lot of time, space and of course energy.
The two elements that produce background radiation on earth are Radon and Uranium. Airborne radon can decay on its own. Radon undergoes alpha decay to produce Polonium. Uranium naturally undergoes alpha decay to produce Thorium.
