초록

The method for verifying analytical technology in the field of radioactivity measurement involves participation in a proficiency test(PT). Proficiency tests are mandatory requirements of ISO/IEC 17025 for maintaining calibration and testing laboratories. These tests are intended to evaluate the analytical capabilities of laboratories, identify problems, support corrective actions, and verify uncertainties. We conducted a proficiency test on the Environmental Resources Association of America(ERA). In the field of radiochemistry, we participated in RAD 136 and compared our results with those of 24 laboratories world wide. The analytical capability of gamma nuclide was evaluated as satisfactory, warning, or unsatisfactory, according to the Z-score of ISO 13528. The radioactivity of 133Ba, 134Cs, 137Cs, 60Co and 65Zn contained in gamma emitters sample was measured and analyzed, and all the result values |z| < 2 were satisfactory according to the Z-score evaluation criteria. Hence, we received the result Laboratory of Excellence.
