Environmental Protection

Drill sumps should be lined, and drilling fluids controlled, to prevent radiological contamination of surface soils

Appropriate personal protective equipment (PPE) should be provided to ensure radioactive dust is not able to be ingested.

On completion of program all radioactive material must be removed from site or returned to the drill hole.

Drill sludges should be assessed for radioactivity prior to backfilling. If a radiation hazard exists sludges may need to be removed from site.

Temporary capping of holes should be below ground level and holes marked and covered.

Dose calculation should be undertaken at the completion of the program with the results supplied to effected personnel and the Department.
