TLD Dosimeters
TLD Dosimeters are one of the most advanced application of
Themoluminescent Detectors. The reason for this is
that, according to the new
10 CFR Part 20 Guidelines of the US NRC,
modern TLD Dosimeters measure the Skin Dose, Eye Dose and Deep Dose specified
in this regulation, in addition to the dose due to other nuclear particles.
Thus, modern TLD Dosimeters consist of at least four separate TL detectors,
which are shielded by materials of various compositions and thicknesses,
to allow for discrimination of photon energies and the nature of the incident
radiation.
Response Functions of TLD Dosimeters to photons of various energies can
be calculated by the microcomputer program
PHOTCOEF. After exposure, the TLDs of
dosimeters are subjected to a Read Process, after which a
Dose Conversion Algorithm is used to convert the outputs of the TLDs to
total dose.
