Abstract :� � Keeping pace with other new technology, Radio Frequency Identification (RFID) technologies have been widely used to increase the efficiency of supply chain operation, store and inventory management and industrial production. The cutting-edge data capture capabilities of RFID systems, in addition to unique product identification and instantaneous information from various data sources, develop efficient management of supply chain processes and logistics, real-time visibility of the stock pile, security and decision support. As a result, RFID technologies have been employed by the military to gain in-transit visibility and improve inventory management. Nevertheless, the risks of using RFID are still critical factors in some areas of military production, especially in munition and explosive productions. The US DoD policy states that those items are not to be tagged until the following certification requirements are met for the passive RFID tag: electromagnetic effects on the environment (E3) and Hazards of Electromagnetic Radiation to Ordnance (HERO). In this paper the Recommended Power Densities and Safe Separation Distance (SSD) for HERO on RFID systems employed on rocket motor raw material and motor charging process are discussed. The result of this research found that RFID readers can be safely operated at close distances to the rocket motor base on AF Guidance Memorandum immediately changing AFMAN 91-201.
