本研究因應國際化與標準化，依據國際標準組織\"International Organization for Standardization"（以下簡稱ISO）所建議之X-射線射質，建立空氣克馬率校正系統。本文探討複製ISO-4037-1規範所建議之X-射線之方法及評估複製之結果，複製完成之X-射線，經評估結果均能符合ISO-4037-1規範要求。

In response to internationalization and standardization, the National Radiation Standard Laboratory (NRSL) established in 2004 the air KERMA calibration system using the x-ray radiation beams recommended by the International Organization For Standardization (ISO). NRSL purchased the x-ray machine, fabricated the filters, assembled the system and duplicated the x-rays recommended by ISO-4037-1. This report presents how we duplicated the x-rays recommended by ISO-4037-1 and the evaluations of the duplicated results. The x-rays duplicated by NRSL were evaluated and the results showed to meet the requirements of ISO-4037-1.
