It is important that study gamma - ray spectrometry of field rock and soil in the earth ' s crust. its energies range between 30kev and 3000kev, where there is much information of natural radioactive nuclides, such as uranium, thorium, potassium, and information of artificial radioactive nuclides, such as cesium, americium, cobalt, and information of the results in interaction between gamma - ray and earth ' s crust
研究表明：野外地面射線能譜測量主要研究地殼巖石土壤中產生的能量約為30kev 3000kev的射線，這裡面包含著鈾、釷、鉀等天然放射性核素信息，核工程活動產生的大量人工放射性核素信息以及射線與地殼相互作用產生的相關信息。 -
In order to meet the requirements of nda measurement, the laboratory of technical research for nuclear safeguards of china institute of atomic energy ( ciae ), is being in charge of developing four sets of nda standards : one set of segmented gamma - ray scanner ( sgs ) uranium standard, one set of sgs plutonhim standard, one set of plutonium isotopic standard, and one set of active well coincidence counter ( awcc ) standard. in this dissertation some pivotal techniques on quality control in developing of nda nuclear standards above were emphatically studied
中國原子能科學研究院核保障技術重點實驗室研製分段y掃描裝置（ sgs ： segmentedgamma - rayscanner ）鈾工作標準樣品、 sgs鈈工作標準樣品、鈈同位素標準樣品和有源中子井型符合計數裝置（ awcc ： activewellcoincidencecounter ）鈾工作標準樣品來滿足核材料nda測量的要求。本論文重點對上述nda核標準樣品研製過程中質量控制的一些關鍵技術進行了研究。 -
It ' s a more accurate method in determining the isotopic abundance of uranium. the paper describes the measurement principles that allow accurate measurements to be taken on samples of arbitrary size, shape, and measurement geometry - and of arbitrary physical and chemical composition - through the use of know nuclear decay data ( half - lives and branching intensities ). this method relies on internal gamma - ray peaks from the spectrum under analysis to self - calibrate the unknown spectrum for energy and peak shape
本工作首次分析了pc fram軟體的演算法並使用高純鍺探測器探測歐共體低濃鈾標準樣品，使用pc fram軟體的預設參數並不能得到準確的富集度值，通過大量的實驗，本工作對鈾富集度測量中的關鍵問題進行了初步的研究並給出了本實驗室條件下準確分析鈾富集度的修正參數和條件。 -
Standard test method for gamma energy emission from fission products in uranium hexafluoride
六氟化鈾裂變產物釋放的射線能量輻射的標準試驗方法 -
The encoding of the data by ann approach is a promising method for the measurement of uranium samples. the determination of the shielded uranium, in particular, by passive gamma - ray detection is a formidable challenge. gamma rays are ideal probes for determining the attributes of uranium in nuclear material transparency monitoring and verification of safeguards regime
2 % ;封裝濃縮鈾屬性的判定一直是nda測量技術中的難點問題，本工作提出了一種輔助探測的方法並給出了高濃鈾的判定依據，該方法通過探測232u衰變子體核素208t1的2614 ， 75kev特徵射線能峰確定鈾樣品中是否存在232u ，從而判定封裝樣品是否為高濃鈾。 -
It ' s hard to detect the attributes of inhomogeneous uranium in large compact containers with normal non - destructive assay methods. a non - destructive gamma ray assay method is provided in this paper. the attributes of uranium can be known by determining the high energy gamma ray 2614. 75 kev
本方法的原理在國外的某些報告中簡單提到過，在國內尚未見到同類研究工作，本工作通過理論分析和能譜分析驗證了從鈾-鈈循環中得到的濃縮鈾會有少量232u的積累或玷污，並且在較厚金屬屏蔽的情況下也可以有效測定2614 -
The data of natural gamma ray spectrum logging are of well conformity with the contents of thorium, uranium and potassium obtained by surface gamma ray survey, laboratory analysis and aerial gamma ray spectrum survey
對自然伽馬能譜測井儀、地面伽馬能譜、室內分析、航空伽馬能譜測量的同一地點釷、鈾、鉀元素含量進行對比分析得知，各種方法所得結果具有較好的一致性。
