摘要： PURPOSE:To obtain a compact radiation detector for detecting deposit on an inner surface, which can readily measure even the thickness of the deposit on the inner surface of a pipe or the like arranged in a narrow place. CONSTITUTION:A detecting part 2, which detects the radiation dose transmitted through an object to be measured as an electrical signal, and an amplifier 4, which amplifies the detected signal from the detecting part 2 and sends out the output signal to the outside, are independently formed, respectively, and connected with a coaxial cable 6. The detecting part 2 is formed by combining a cesium iodide crystal 8 surrounded with a light reflecting material 7 and a photodiode 9.

摘要： PROBLEM TO BE SOLVED: To provide an analysis result display method capable of improving the contrast of a transmission X-ray image.
SOLUTION: The number of pulses corresponding to the output level of the transmission X-ray outputted from a transmission X-ray detector 28 is counted by a counting means such as a multi-channel analyzer. In the counting means, number of pulses is counted for each output level, and the counted values are stored in a memory. An X-ray analyzer 1 extracts the counted values corresponding to the output level in a specified range among the counted values corresponding to the output level counted by the counting means. Based on the counted values corresponding to the extracted output level, the analyzer generates a transmission X-ray image and outputs the generated transmission X-ray image to a display device.

摘要： PURPOSE:To enable highly accurate analysis by using a proportional counter tube as an X-ray detector to detect a shift of a peak position of X-rays whose existence and position of the energy peak contained in secondary X-rays are known and by controlling applied voltage of the proportional counter tube based on the detection results. CONSTITUTION:A peak position shift detection unit 13 comprises a digital window comparator 14, a digital subtractor 15, a D-A converter 16 and an integrator 17 which are connected in series. An output of the D-A converter 10 is input to the comparator 14, and an output of the integrator 17 is input to a control unit of a high voltage power source 8 for driving a proportional counter tube 4. The comparator 14 determines whether or not information X regarding scattered X-rays 6 as X-rays whose existence and position of the energy peak contained in secondary X-rays 7 are known is in a predetermined energy range, while the subtractor 15 calculates difference between the information X and the peak energy of the X-rays 6 to output the subtraction output. This output is converted by the converter 16 and integrated by the integrator 17.

摘要： PURPOSE:To display measurement values accurately by adding uniform random numbers to the output counts from a radiation detector, multiplying the sum by a predetermined coefficient, and omitting the fractions of the product to arrange the digit thereby improving the nonlinearity in the differentiation of least significant digit being displayed. CONSTITUTION:Radiation H is detected by a detector 1 and a signal is delivered to a preamplifier 2. Output signal (a) from the preamplifier 2 is amplified and filtered through a linear amplifier 3 to produce a signal (b). The level of the signal (b) is decided by a signal channel analyzer 4 and a signal (c) having magnitude larger than a predetermined level is outputted. A counter 5 counts the signal (c) a predetermined time and outputs a count N every time when the counting is ended. Uniform random numbers (r) generated from a random number generator 6 is added 7 to the count N and the sum is fed to an operating unit 8 where the sum is multiplied by a coefficient for unit conversion and the digit is arranged by omitting the fractions of the product thus providing a digit to be displayed.
