Thermoluminescent Dosimetry

Operating principle / measuring cycle: 1) TLD detectors (TLD chips) inside TLD dosimeter collect energy of ionizing radiation proportional to dose of exposure. 2) Been heated the TLD chips release collected energy in the form of light emission. 3) Photomultiplier tube (PMT) located in TLD reader detects the emitted light and converts it into electrical signal.
