1. Historical information
Valuable information can be obtained from the different records that have been kept for the area under investigation.
If no historical information is available, a worse case scenario must be assumed. Information will need to be gathered about the area through an initial survey to assess dose rate and contamination levels before the monitoring strategy is established. The survey may include:
- dose rate checks
- monitoring for alpha /beta /gamma contamination levels
- air sampling coupled with alpha/beta/gamma spectrometry
- surface wipes coupled with alpha/beta/gamma spectrometry
- liquid scintillation counting
