X fluorescence can quickly carry out measurement without damage and motion. it was widely adopted in geology, mining, environmental - protection, archaeology and industrial - analysis. its principium is that in measurement of radioactivity, the pulse energy is directly proportional to pulse signal amplitude detected by the radiation detector
X熒光方法可以實現快速、原位、無損測量，被廣泛應用於地質、礦業、環保、考古、工業在線分析等領域，其原理是：在核能譜測量工作中探測器輸出的脈沖信號與入射粒子的能量成正比，通過測量脈沖信號幅度，得到入射粒子的能量。 -
Basing on the mcnp software, the author solved the matter by calculating the value of point to replacing the value of cell or surface. the research searched out a new means to solve similar matters. by using the studying result, the author programmed the gamma code, with the interface of window, which can simulate the course that a y - detector measures the radioactivity in soil and calculate the dose ratio and the chart of energy deposition
作者以以上方法為基礎開發出了就地譜儀模擬軟體gamma ，軟體基於mcnp軟體平臺，具有可視化介面，用於模擬譜儀現場測量，可視化窗口界面使用戶可以方便地調節探測器內部結構的幾何尺寸及窗材料、測量高度、射線能量及發射率、核素在土壤中的分佈規律等參數，方便工程技術人員的使用。 -
The object of single photon emission computed tomography ( spect ) is to reconstruct an unknown radioactivity distribution inside the body from projection data consisting of the number of photon collected on a collimated gamma camera. these projections are not simple line integrals but have point - spreads due to the imperfect collimator of the detector and attenuation due to the compton scattering. so
這種投影數據與透射ct中的數據不同，由於存在著光子的點擴散（由準直器引起）和衰減（由散射引起） ，已經不能用簡單的線積分來描述這個問題，因此相對于透射ct而言，這個領域將面臨很多困難。 -
The methods of performance recovery by cleaning and disposal for au - si surface barrier detector that performance deteriorated and can ' t be used normally owing to be contaminated by radioactivity materiel, powder and oil, have been recommended
摘要介紹了金矽面壘探測器因放射性的污染或粉塵、油漬等污物的沾附，致使其性能變壞而無法正常使用時，通過清洗和一定的處置使其性能恢復的方法。
