Advantages and Disadvantages of Electronic Personal Dosimeters

An electronic personal dosimeter is a modern dosimeter that can give a continuous readout of cumulative dose and current dose rate and warn the person wearing it when a specified dose rate or a cumulative dose is exceeded. EPDs are especially useful in high-dose areas where the residence time of the wearer is limited due to dose constraints.

Advantages and Disadvantages of Electronic Personal Dosimeters

Advantages of Electronic Personal Dosimeters

  • EPDs can display a direct reading of the detected dose and dose rate in real-time.
  • EPDs have a dose rate alarm and a dose alarm, which warn the person wearing it when a specified dose rate or a cumulative dose is exceeded.
  • The dosimeter can be reset, usually after taking a reading for record purposes, and thereby re-used multiple times.
  • EPDs can measure a wide radiation dose range from routine (μSv) levels to emergency levels (hundreds mSv or units of Sieverts) with high precision.

Disadvantages of Electronic Personal Dosimeters

  • EPDs are generally the most expensive dosimeters.
  • EPDs are generally large.
  • EPDs measure and record radiation exposure due to gamma rays, X-rays, and sometimes beta particles. For neutrons, TLDs are more capable.
