The Performance of TLD-BARC's PTKMR-BATAN on the Intercomparison of Hp(10) in the Year of 2016-2018 Held by SSDL Jakarta

For accreditation requirements, laboratories are required to take part in an intercomparison program based on ISO / IEC-17025:2017. Testing or calibration laboratories that apply for accreditation to National Accreditation Committee (NAC) must have followed at least one intercomparison program. If there is no intercomparison program available, the laboratory must prove its capabilities as in ISO / IEC-17025 item 5.9.a. Laboratories that have been accredited by (NAC) are required to take part in the comparison of measurements at least once a year. For the main scope of accreditation, the laboratory must take the proficiency test once in its accreditation period. In Indonesia, non-radiation intercomparison is usually managed by NAC, while the radiation intercomparison, such as dose quality audit of Hp (10) is managed by the Secondary Standard Dosimetry Laboratory (SSDL) - Jakarta. As we know, the performance of a dosimetry material or equipment can change or decrease due to the time function (aging) or because of the frequency of use. For this reason, observations have been made on the performance of TLD-BARC from the results of Hp(10) intercomparison during 2016-2018. It was used ANSI (American National Standard Institute) criteria for the assessment. This paper presents the performance of TLD-BARC's PTKMR BATAN on the intercomparison of Hp(10) in the year of 2016-2018, held by SSDL-Jakarta.
