What is Advantage and Disadvantage of Electronic Personal Dosimeters – Definition

by
Advantages and Disadvantages of Electronic Personal Dosimeters. EPDs are able to 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 can warn the person wearing it when a specified dose rate or a cumulative dose is exceeded. Radiation Dosimetry

An electronic personal dosimeter is modern dosimeter, which can give a continuous readout of cumulative dose and current dose rate, and can 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 residence time of the wearer is limited due to dose constraints.

Advantages and Disadvantages of Electronic Personal Dosimeters

Advantages of Electronic Personal Dosimeters

  • EPDs are able to 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 can 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 are capable of measuring 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 in size.
  • EPDs are used to measure and record radiation exposure due to gamma rays, X-rays, sometimes beta particles. For neutrons, TLDs are more capable.
