The complex nature of the terrain presented a number of challenges for the ARPS team. The land comprised areas of dense woodland, overgrown vegetation, excavated soft ground and roads comprising concrete or tarmac as well as construction access roads made up of compacted soil. There were also some steep gradients with unstable ground adjacent to sheer drops. Walking conditions on the site were mixed but the team managed to access most areas, using a GT-40 survey meter to detect gamma radiation. Background radiation levels in the general vicinity also had to be considered when calculating the overall outcome of the survey.
