  1. Possession Licence—have overall ownership and control of radiation source
  2. Approval to Acquire—purchase or otherwise obtain a radiation source
  3. Use Licence—perform a geotechnical measurement purpose.

Geotechnical measurement business purposes include:

  • density/moisture measurements for road base preparation
  • density measurement for testing asphalt compaction
  • moisture measurement for testing soil hydrology.

You may also need to relocate or dispose of radiation sources or transport a radioactive substance.
