Reference Approach for Human Intruder Dose Assessment for Deep Geological Disposal

Human intrusion has been considered an issue in post-closure safety of solid radioactive disposal for many years but is problematic due to the difficulty of justifying assumptions about human behaviour over relevantly long periods of time. A project is therefore underway which aims to:

• examine the technical aspects of why and how such intrusion might occur,
• consider how and to what degree exposure to the people involved would follow,
• identify the processes which constrain the uncertainties, and hence
• develop and document a reference approach for evaluation of the human intruder doses.

The work programme is due to complete in 2011. For further information, please contact Graham Smith (GMSAbingdon[at]btinternet.com).
