Abstract
This paper describes a summary of results in a series of 10 international intercomparisons of environmental dosimeters held during 1974-1993 and another series of domestic Intercomparison studies held in Taiwan during 1980-1984. The field conditions were harsh. Even in semitropical Taiwan where high humidity and temperature in the field is usual, the performance of our TLD could pass all the rigid tests. The ANSI N13-29 (American National Standards Institute publication N13-29) dealing with standards for environmental dosimetry and the Horlick's triangle dealing with the accuracy and the precision of TLD were used to analyze the dosimeterc data.
