description: The data files are separated into the following categories.
[1] Introduction and Contents
Files detail outline requirements for the initial investigations and the PhD project proposal.

[2] Calculations and Results
Files: 8,161
These files contain:
Analysed Site Gamma Monitoring Data. These are the gamma monitoring files for the detectors on the EW building during the construction phase of the East Wing cladding.

CERC ADMS Supplied Data. An ADMS receptor points map and doses calculated from the concentration field and gamma-ray dose module of ADMS, these are detailed in the paper reproduced in the thesis.

Detectors and layouts. This sub-folder contains details of the detector positions on the EW building and the wind logger calibration test certificate.

Experiment #2 Results. This folder contains sub-folders with the results according to the experimental numbering scheme specified in chapter 3 of the PhD thesis.

Experiment #3 Results. This folder contains sub-folders with the results according to the experimental numbering scheme specified in chapter 3 of the PhD thesis. Also included are processed results showing the measured velocity flow.

field for the cube and EW clad buildings. Data is also included showing the puff release measurements and continuous release measurements. Graphical data is included on the measurement planes with respect to the EW building.

Experiment #4 Results. Experiment #4 methods document details the experimental investigations. Results are presented for the cube and EW flow fields. Also, the leading-edge effective distance from the building of the release point is shown.

Experiment #5 Results. An experiment series #5 data spreadsheet is given summarizing the results along with the document covering the experimental investigations. Along with this there are graphical results from the flow field for different cases using a plotting program. Spreadsheets are presented that contain the experimental results for various building configurations and downstream distances, X.

Paper #1 Results. Various spreadsheets are presented showing the calculations for the initial first paper reproduced in the thesis.
Photographs: of smoke releases are shown for the EW full building model. Also, a variety of photographs of the wind tunnel cube experiments.

[5] Conclusions and Output Reports
Files: 19
The files cover presentations presented at different forums during the course of the PhD work about findings from the project. Also included is a radiological assessment report submitted to the Environment Agency after the initial radiological assessment of the site discharges. There are various power-point presentations made on completion of the PhD work. Another set of files cover the reports submitted by CERC, Cambridge, that were referenced in the first published paper cited in the PhD thesis. The folder includes the final PhD thesis after corrections and award.
