TLD-DN-02** / ver. 12 (apr. 2020)

in-house method on the basis of modified standard method IEC 62387

Dose Hp(10), H*(10), air-Kerma and Hp(0,07) for usage in personal and environmental dosimetry Measurements with TL dosemeters

Measurement range of TLD system:

0,0075 mSv – 5 Sv

for energy range

40 keV – 1,2 MeV



* Laboratory can implement minor modifications of the method as necessary (e.g. adaptation to the new version). Detailes on the actual state of the scope is maintained by the laboratory.

** In April 2020 complete revision of the procedure was performed. Updates due to the new revision of the IEC 62387 standard (ed. 2.0, January 2020) were implemented and a complete revision of the uncertainty budget was performed. Besides improvements in the response of the finger dosemeters at different energies were introduced.
