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. Current Implementation
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.

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.

19. Any questions?
