近年來，醫學界應用高能輻射進行診斷與醫療，劑量標定羲為空氣克馬及水中的吸收劑量，由於水在人體中占70%，因此可把水等效於人體。醫學界於水吸收劑量量測時，要利用經鈷－60標凖場進行校正的腔型遊離腔，再將遊離腔置於假體中量測高能輻射場的電荷量，利用AAPM 21或AAPM 51號議定書之運算，即可得到人體中之劑量。對於以化學氣相沉積法（Chemical Vapour Deposition，簡稱CVD）産生的鑽石薄膜(CVD Diamond films)，其熱發光的輝光曲線及其動力學的特性，已有多位研究人員發表其研究成果。但是在實際的應用上必須將得到的輝光曲線存入電腦中，將資料的格式轉換後再利用擬合程式進行分析，才能計讀出輻射劑量。因此，本研究的主軸在使用CVD攢鑽石薄膜作為高能輻射的劑量量測工具，利用各單位現在的設備即可進行相關的研究。由於CVD鑽石薄膜以碳原子為主，其原子序數為6輿水的平均原子序數7.4相近，故可視為一等效組織材料，在吸收劑量的量測上非常方便，實驗結果顯示CVD鑽石薄膜量測高能輻射劑量的實用性。

Recently, high energy radiation has been used for medical diagnosis and treatment, and the standard dosimetry is defined as air kerma and absorbed dose to water. Because human's body contains 70% water, so it can be assumed that body is water equivalent. To measure the absorbed dose to water in medical radiation oncology, an ion chamber calibrated with colbat-60 irradiation is used together with a phantom to measure the electric charge after being exposed to high energy radiation, and then according to AAPM No.21 or No.51, the human's body dose can be calculated. Many research workers have investigated the glow curve and dynamic of CVD diamond film fabricated with chemical vapour deposition methods (CVD method), and they have also used computer code for glow curve fitting and identification of the light source interference from radiation. In practice, the glow curve must be analyzed by computer, in order to obtain the dose. This work is to study CVD diamond as a tool for radiation dosimetry, and to find the reading modular similar to TLD which can then be used in laboratories. The main component of CVD diamond film is carbon, its atomic number is 6 which is close the mean atomic number of 7.4 for water, it can be used as a tissue equivalent material, and is convenient to measure absorbed dose to water. Results of experiment show that the difference between absolute dose measured and dose profile obtained is about �10%. The CVD diamond is a practical material for high-energy radiation measurements.
