Appendix 4: X-Ray Laboratories and Isotope Geochemistry

Local Rules for Working with Small Natural Radioactive Samples

The principal hazards with small samples of natural radioactive compounds are:

  1. Inhalation
  2. Ingestion


  • Do not eat, drink, or smoke whilst you are handling radioactive samples
  • Keep samples in sealed containers opening them only when a sample is needed
  • Always wear disposable gloves when handling specimens
  • Use wet methods whenever possible (e.g. for grinding); if wet methods are unsuitable use a fume cupboard
  • Clean the bench area after use with damp cloths
  • Dispose of cloths and gloves in a plastic bag after use
  • Wash your hands
