A tracking system for items to be ionizing radiation sterilized is provided which utilizes an attached RF ID tag that is ionizing radiation proof or enclosed in an ionizing radiation proof holder. The RF ID tag is coded with a unique identification and certification data on the ionizing radiation sterilization. An RF ID tag reader is provided, which is usable by a user to obtain the identification and sterilization data from the RF ID tag on the item. The RF ID tag reader includes a user input for at least one trackable event and can write data based on the at least one trackable event back onto the RF ID tag. The RF ID tag reader is at least one of connectable to a PC or the internet, or is compatible for uploading the identification and any user input to an internet accessible device. A database is provided, having item related information. The database provides access to a user to obtain related information based on the identification from the RF ID tag and receives and stores data related to the at least one trackable event.

1. A tracking system for gamma radiation irradiated lots of items, comprising: an RF ID tracking tag assembly including a rewriteable FRAM (Ferroelectric Random Access Memory) memory storage component, that is not adversely affected by gamma radiation sterilization;the rewriteable FRAM memory storage component including a unique identification and a memory, and at least one trackable event being writable to the memory;a memory reader which is usable by a user to obtain the identification from the memory storage component after it has been gamma radiation irradiated and which can read the at least one trackable event stored in the memory. 2. The tracking system of claim 1, wherein the tracking tag assembly further includes a dosimeter that records a level of gamma radiation to which the tag is exposed. 3. The tracking system of claim 2, wherein the at least one trackable event comprises at least one of a sterilization certification, a radiation level or a dosimetry record. 4. The tracking system of claim 3, wherein additional trackable events are stored in the memory including at least one of a manufacturing date, a batch number, a lot number, material specifications, material lot number, certifications for sterility, certificates of compliance, size specifications, functional specifications, description, customer data, or customer application associated with the identification. 5. The tracking system of claim 1, wherein the memory reader is a RF ID tag reader that is connectable to PC, internet accessible device or internet for communication of data to a centralized database. 6. The tracking system of claim 1, wherein the at least one trackable event includes at least one of a manufacturing date, a batch number, a lot number, material specifications, material lot number, certifications for sterility, certificates of compliance, size specifications, functional specifications, description, dosimetry records, sterilization certifications, customer data or customer application associated with the identification. 7. The tracking system of claim 3, wherein the tracking tag assembly comprises an external pouch, molded strap or laminations surrounding the RF ID tag. 8. The tracking system of claim 7, wherein the laminations comprise layers of a bag or pouch and the RF ID tag is sealed between the laminations in a seam area of the bag or pouch. 9. The tracking system of claim 3, wherein the tracking tag assembly comprises a holder formed from two pieces of laminate that are made of a polymeric material with the RF ID tag sandwiched between the laminates. 10. The tracking system of claim 1, wherein the tracking tag assembly is integrally molded onto an item to be tracked. 11. The tracking system of claim 1, further comprising a local tracking history database in which data from the memory reader can be stored and tracked for each of the items being tracked. 12. The tracking system of claim 1, further comprising a history analysis and reorder system that analyzes the local history databases to determine a shelf life of the item being tracked or its contents. 13. A method of tracking items to be gamma radiation irradiated using a tracking system, comprising, affixing an RF ID tracking tag assembly with a rewriteable FRAM memory storage component that is not adversely effected by gamma radiation sterilization on the item to be irradiated;subjecting the item to gamma radiation irradiation for sterilization;writing data to the rewriteable FRAM memory storage component before or after being subjected to the gamma radiation sterilization;providing information relating to the irradiated item to a data base correlated to an identification data which is stored in said FRAM memory storage component; anda user reading the rewriteable FRAM memory storage component on the item with a memory reader. 14. The method of claim 13, further comprising: the user inputting at least one trackable event regarding the gamma radiation irradiated item into the memory reader which is a memory reader/writer;the memory reader/writer writing the information relating to the gamma radiation irradiated item or at least one trackable event regarding the irradiated item back on the rewriteable FRAM memory storage component; anduploading data from the memory reader to a PC or an internet accessible device or connecting the memory reader to an internet;accessing the data base;retrieving data relating to the gamma radiation irradiated item from the data base; anduploading data on the at least one trackable event to the data base to build the data base. 15. The method of claim 14, wherein the memory reader is an RF ID tag reader that can read the RF ID tag without physical contact therewith. 16. The method of claim 15, wherein the tracking tag assembly further includes a dosimeter that records a level of radiation; and the method further includes reading the radiation level recorded by the dosimeter; and writing radiation level data to the RF ID tag or adding the radiation level data to the data base correlated to the RF ID tag for the item. 17. The method of claim 13, wherein the item is a bag or pouch, and the method further comprises sealing the tracking tag assembly into a seam of the bag or pouch. 18. A method of tracking gamma radiation sterilized lots of items using a tracking system, comprising: positioning at least one tracking tag assembly including an RF ID tag with a rewriteable FRAM memory storage component that is resistant to gamma radiation sterilization and a dosimeter in a lot of items;gamma radiation sterilizing the lot of items;determining gamma radiation exposure using the dosimeter; andwriting sterilization data determined from the dosimeter to the RF ID tag or to a data base correlated with the RF ID tag identification. 19. The method of claim 18, further comprising: providing a plurality of the tracking tag assemblies;locating the tracking tag assemblies according to a set pattern or based on a predetermined map in the lot of items;determining sterilization data from each of the dosimeters of the tracking tag assemblies to provide a dose map for the lot of items. 20. The method of claim 19, further comprising: writing the locations of the tracking tag assemblies to the respective RF ID tags of the tracking tag assemblies. 21. The method of claim 19, further comprising: writing the sterilization data to the respective RF ID tags of the tracking tag assemblies. 22. The method of claim 19, further comprising: loading the location data for the tracking tag assemblies and the sterilization data to the database. 23. The method of claim 13, wherein the item comprises at least one of liners for vessels, bags, filters, medical devices, or pharmaceutical, chemical or biological processing devices.
