Glass dosimeter developed by Piesch for measuring the absorbed dose in critical organs, in which only one FD-P8-1 glass was encased in asuitable badge case, was examined for the case of FD-3 glass, FGD-6 type Fluorimeter, standard Japanese man phantom, and a badge case manufactured by us.
This experiment confirmed the same validity for this case as well as the case of FD-1 glass, FGD-3B type Fluorimeter and Alderson man phantom which were used used by Piesch.
The merits of this glass dosimeter against other dosimeters are discussed from the view point of the personnel dosimetry for radiation protection.
