中文摘要 | 本研究基於釷礦精煉時僅存有□Th和□Th且□Th的質量相對於□Th可忽略不計, 確立了含釷煤氣燈罩的□Th活度和齡期的準確測定方法,針對市面購得不同包裝的兩種廠牌 含釷煤氣燈罩進行了□Th活度測定和齡期推估,測定的結果並與國外的研究相互印証。 |
英文摘要 | A technique for measurement of □Th activity and product age in thoriated gas mantle was established on the basis that both □Th and □Th, but none of the daughters, remain in Th after extraction and purification process from ore, and the mass of □Th is negligible comparing with □Th. Measurement of gas mantles of different batches from two brands was performed, and the results were compared with literature studies. |
