Manually
operated reader for evaluation of single
thermoluminescent dosemeters
Features
► Compact, easy
to use table-top TLD reader for manual
operation
► Suitable for
all types of TL detectors, including powder
► Provides a
maximum heating temperature of 500°C
► Includes
Windows software
The LTM
reader is designed to measure accumulated
dose signals from thermoluminescent
dosemeters. Any type of TLD material can be
used, i.e., chips, rods, film (ribbons) or
powder. For processing, the TL dosemeter is
placed on one of the interchangeable
planchets for contact heating. The optical
filters can also be changed optionally. The
preheating and the heating process on linear
temperature ramps of up to 500 °C are
controlled automatically with an accuracy of
better than 1 0/0. The measuring range
covers seven decades with a linear response
of up to 12 Gy using standard TLD material
and up to 500 Gy using material LiF:Mg,Ti.
The background reading is corrected
automatically before starting each
measurement. An internal reference light
provides for automatic calibration of the
photomultiplier. The dose reading can be
calibrated in the radiation units Gy, Sv,
rem orrad or in the unit C (electrical
charge). The LTM system is prepared for TLD
evaluation under nitrogen atmosphere.
Windows software for reader control, storage
of measuring results, statistical evaluation
and glow curve printing is included in the
standard package. If TL powder is used with
the LTM manual reader, various optional
powder accessories are required to handle
the powder.

The PCL3 is
an automatic reader to measure accumulated
dose signals from thermoluminescent
dosemeters. Up to 80 detectors can be
evaluated in one cycle. The detectors are
stored in a magazine, automatically
processed and loaded into a second magazine.
TL chips of 4.5 mm diameter and 0.8 mm
thickness and TL powder are preferably used,
alternatively TL rods and TL films are
suitable. The detectors are heated by
contact. The heating temperature of maximum
600 °C is controlled automatically with an
accuracy of bet- ter than 1 0/0. The
measuring range covers seven decades with a
linear response of up to 12 Gy using
standard TLD material and up to 500 Gy using
material LiF:Mg,Ti. The background reading
is corrected automatically before starting
each measurement. An internal reference
light provides for automatic calibration of
the photomultiplier. The dose reading can be
calibrated in the radiation units Gy, Sv,
rem or rad or in the unit C (electrical
charge). The PCL3 system is prepared for TLD
evaluation under nitrogen atmosphere.
Optionally the PCL3 system enables the user
to calibrate the TL detectors with a
built-in radioactive calibration source. The
modular cabinet design of the device
presents very easy access to the mechanical
and electronic components for maintenance
and repair. A computer software for control
and evaluation is included in the standard
package. If TL powder is used with the PCL3
reader, various powder accessories are
required
