              About How Different Sterilisation Methods Were Developed? 
              
 During time of conflict and war, new sterilization methods tend to 
              be developed. EO sterilization was developed after WWII for germ 
              warfare. Radiation was driven in part during the cold war as a 
              means of using unused source of radiation. In the terrorist 
              anthrax challenge, x-ray irradiation appears to be a practical 
              means of sterilizing / sanitizing pallets of mail against anthrax, 
              that other current methods couldn’t complete adequately or in 
              time. For the first time in history we have x-rays and the 
              capability of sterilizing bulk, dense mass and large volume of 
              untreated (contaminated) healthcare product in a matter of 
              minutes, just in time, without the additional handling associated 
              with unloading and loading.
