About the Calibration Light Source
The TLD reader uses a calibration light source (CAL) that generates a weak light having constant and
stable light amount generated source to check the soundness of the photomultiplier tube. This calibration
light source is the sealed and solidified fluorescent material and radioactive substance “14C” using silicon
resin. The calibration light source is the sealed radiation source of approx.370 kBq (approx.10 μCi).
As for the legal treatment, this can be handled as a radiation source out of the scope of laws and
ordinances since the lower limit “14C” is 10 MBq.
However, since this contains a radioactive substance, it is recommended to dispose of the reader
separately from general wastes even though this is out of the scope of laws and ordinances,
