PSM · Environmental health: personal radiation monitoring

Sample item

Which device is worn by radiology staff to record their cumulative occupational radiation dose?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Thermoluminescent dosimeter badge

A thermoluminescent dosimeter badge is worn on the body and later read to give the cumulative dose received. A Geiger-Muller counter is a survey instrument for detecting radiation in an area. A lead apron shields but does not measure.

Option by option

  • A. Gamma camera

    A gamma camera is an imaging device for nuclear medicine.

  • B. Thermoluminescent dosimeter badge (correct)

    Correct. A TLD badge records the personal cumulative dose.

  • C. Lead apron

    A lead apron reduces exposure but does not measure it.

  • D. Geiger-Muller survey meter

    A survey meter measures radiation in a place at a moment and is not worn for dose.
