* 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.

** Complete reevaluation of the tritium activity calculation was performed in 2017, including determination of characteristic limits and other parameters based on the standard ISO 11929.  In year 2020 minor updates of the programmes for data evaluation were performed.

*** In the year 2021 the regular revision of the procedure was performed, minor changes were implemented.
