  1. RFID Source Tracking Tim Durkin PPD

  2. Legislation • The Ionising Radiations Regulations act 1999. • Applicable to industry, research, military, civil service and healthcare. • Applicable anywhere individuals have the potential to be exposed to ionising radiation.

  3. Legislation • Sections 28 and 29 of IRR99 describe a requirement for the accountancy of radioactive substance. This relates to the daily movement of sources and suitable storage.

  4. Legislation • New legislation came into effect in 2005. • ‘The high activity sealed radioactive sources and orphan sources regulations (HASS)’ • Among other things, describe stricter security requirements for sources whose activity is over a specified threshold.

  5. A lockable source store, usually a safe. Each source as an individual container. Authorised individuals are allowed access. Location register and source movement are tracked by hand in a hardback book. Current Implementation

  6. Radio frequency identification • Passive device that broadcasts data when activated by an RF field. • Popular on security badges. • Currently used in stock control applications.

  7. RFID • Operates over a range greater than 3 metres. • Multiple tags can be read simultaneously. • Possible to update the memory on each of the tags.

  8. Concept • Each source holder is tagged with an RFDI chip. • Each radiation worker is issued with a licence with an embedded RFDI chip. • Every source store has to RFDI readers, one internal and one external. • Every source store has and electromechanical lock fitted and linked to the RFDI network.

  16. Development programme • Stage One: • Determine if the technology can be used within a radioactive environment. • RFID development kit will answer that question.

  17. Development programme • Stage Two: • Design and produce the ‘smart safe’. • This will require mechanical and electronic expertise.

  18. Development programme • Stage Three: • Interface with iso-stock control software. • This will require help from iso-stock and alien RFID. Both parties have shown interest.
