| 3. | TLD-DN-02** / ver. 12 (apr. 2020) in-house method on the basis of modified standard method IEC 62387 | Air kerma, ambient dose equivalent H*(10) and personal dose equivalent Hp(10) 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 | Dosemeter tablets TLD-400 |
* 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.
