Areas to Survey in a Lab

At a minimum your survey needs to cover all radioactive work areas, radioactive storage areas, and areas where contamination is a concern (e.g. break rooms, the desks of common radioisotope users, etc.). Be sure to survey different areas each time to ensure you do not miss contamination in the lab. The number of locations should be based off the type and amount of work since the last survey. These areas should include:

  • Floors in front of your work area
  • Bench tops and work surfaces
  • Non-radioactive trash containers (ensure no radioactivity or visible radiation labels)
  • Fume hoods
  • Sinks (no sink disposal of any radioactivity)
  • Fixed equipment (e.g. hybridization ovens, centrifuges, incubators, LSC, etc.)
  • Frequently handled items (e.g. pipettors, glassware, pens, telephones, door knobs, lab notebooks, keyboards,etc.)
  • Refrigerators and freezers
  • Radioactive waste storage areas
  • Personal protective equipment (e.g. lab coats, safety glasses, reusable gloves, etc.)
  • Any area designated as “clean area”
