TRACKING SYSTEM FOR GAMMA RADIATION STERILIZED BAGS AND DISPOSABLE ITEMS
First Claim
1. A tracking system for ionizing radiation irradiated lots of items, comprising:
- a tracking tag assembly including a memory storage component, that is either not adversely affected by ionizing radiation or encapsulated in an ionizing radiation resistant holder;
the memory storage device 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 ionizing irradiated and which can read the at least one trackable event stored in the memory.

Abstract
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.
