NORM Survey Pre-Operational Checks

Before surveying areas for NORM radiation or contamination, always perform the following four pre-operational checks on the meter.

  1. Physical Check. Meters are delicate and can break if mishandled. Look for any obvious signs of physical damage to the meter.
  2. Calibration Check. Examine the inspection sticker on the meter, and ensure that the last calibration is within the appropriate regulatory guidelines.
  3. Battery Check. Turn the knob to the battery check position and verify that the battery is sufficiently charged.
  4. Response Check. Verify that the meter responds to the check source and registers within 20% of the known amount of radiation. If the meter accurately measures the radiation, all pre-operational checks are complete and surveying can begin.
