摘要： A reference density profile is generated in an outer circumference direction of a pipe having a reference welded portion on the basis of a reference fluoroscopic image generated from a radiation detection medium when a radiation source is disposed on a central axis of the pipe. A weld inspection density profile is generated in an outer circumference direction of a pipe having an inspection target welded portion on the basis of a weld inspection fluoroscopic image. On the basis of the reference density profile and the weld inspection density profile, density correction information is calculated. The density correction information is for correcting density irregularities in the weld inspection fluoroscopic image in the outer circumference direction of the pipe. On the basis of the density correction information, the density irregularities in the weld inspection fluoroscopic image are corrected.

摘要： An apparatus is provided for external inspection of a pipeline circumferential weld. This comprises a radiation source (5) and radiation detector (3). Both units are controllably movable around a drive band or track (7) which is fitted around the circumferential weld. To align the source with the detector the source and detector are moved with respect to each other clockwise and anticlockwise around an initial position whilst sampling the radiation detected at a number of positions. A position of maximum strength of the radiation signal detected can then be determined such that the centre point of the radiation source may be located. The source and detector are then substantially aligned with each other and means are provided to move the source and detector circumferentially around the weld whilst remaining substantially in alignment.

摘要： A method of inspecting the cover of a buried pipeline comprising the operations of irradiating the inner wall of the pipeline with neutrons from a radioactive source carried by a vehicle traversing the pipeline, measuring the intensity of ionizing radiation within the pipeline arising from nuclear interactions occuring within the cover of the pipeline and its surroundings due to the neutrons emitted by the source, and recording the measured intensity of the said ionising radiation together with data representative of the position of the vehicle along the pipeline. Apparatus for carrying out the method also is described.

摘要： A measure is obtained of the relative quantities of radioactive material inside and outside a structure such as a pipe by obtaining two spectra of gamma radiation on a dummy structure of the same shape and composition. A first spectrum is obtained with a quantity of the radioactive element to be measured located inside the structure and a second spectrum is obtained with a quantity of the same contaminant located outside the structure. The two spectra are normalized to the same equivalent value in a portion of the spectrum that does not reflect the presence of gamma rays resulting from Compton scattering in the structure. Comparison of that portion of the spectra obtained where Compton scattering is a factor gives a measure of the relative amounts of contaminants inside and outside the structure on a spectrum obtained from a test structure. The invention may also be practiced by obtaining a plurality of spectra at varying known concentrations inside and outside the dummy structure.
摘要翻译：通过在相同形状和组成的虚拟结构上获得γ辐射的两个光谱，可以获得诸如管道之类的结构内部和外部的放射性物质的相对量的量度。获得第一光谱，其中待测量的放射性元素的量位于结构内部，并且获得具有位于结构外部的相同污染物的量的第二光谱。在光谱的一部分中，两个光谱被归一化为相同的等效值，其不反映由结构中的康普顿散射产生的伽马射线的存在。将康普顿散射作为因子得到的光谱部分进行比较，得出从测试结构获得的光谱中结构内部和外部污染物的相对量的量度。本发明还可以通过在虚拟结构内部和外部以不同已知浓度获得多个光谱来实施。
