BS 7516:1995 核仪器仪表 液体闪烁计数系统 性能验证

The purpose of this International Standard is to provide the user with a means of verifying the performance of typical liquid-scintillation counting systems. Measures of performance considered in this standard are: - counting system efficiency; - reproducibility of sample and background count rates. This standard does not cover the calculation of sample activity for quenched samples. Accordingly, this standard does not deal with sample preparation, efficiency correlation (quench correction) procedures, or the identification of unknown radionuclides.

IEC 61342:1995 核仪器 多脉冲幅度分析仪 主要特性、技术要求和试验方法

This International Standard is applicable to multichannel pulse height (amplitude) analyzers (MCA) with linear amplitude response, which are measuring devices used for acquisition, storage and processing of amplitude distributions. These analyzers automatically carry out the following operations: - acceptance of pulses from detection sub-assemblies or other sources; - analogue-to-digital conversion (ADC) of the pulse height information; - sorting of pulse height data according to predetermined characteristics; - storage of digital information (histogram); - processing of stored pulse height histogram and externally supplied information in accordance with predetermined algorithms; - data input and output functions (for example, driving a display, a printer, a floppy disk drive, a plotter, etc.). The above operations may be accomplished separately or combined in an integrated instrument. All the tests described herein are not mandatory, but if the test is carried out, then it shall be done in accordance with the procedures given herein. In many cases in nuclear physics, it is very important to measure the distribution of certain kinds of parameters, such as the energy of particles, their mass, their distribution in time, their scattering on certain angles, etc. In modern measuring practice, this performance is usually accomplished by means of a multichannel pulse height analyzer. This type of a device is built in such a way that a quantity of a certain physical quality is digitized and then stored according to its digitized number. All modern MCAs contain special storing units (memories) for this purpose. After accomplishing the measurement the required information is retrieved from the memory so that it can be used for interpretation of the physical data. Nowadays, multichannel pulse height analyzers are more widely used in different fields of science and industry. Their specific aim in nuclear applications is to transform the pulse height related to a certain nuclear event (usually energy) into a number corresponding to a memory cell, so that during the measurement one can store a histogram that is very similar to the initial pulse height distribution. This distribution reflects the probability density of particle energy (energy spectrum). Using the stored information about the distribution it is easy to determine the information about the initial energy of the particles (alpha and/or beta-particles, gamma and X-quantum, etc.). Further, this information can be used to determine flux densities, dose rates and doses, isotope and element concentrations and contents, etc. Usually, a pulse height analyzer includes an ADC (analogue-to-digital converter), an acquisition unit, a memory, a display and different input/output (I/O) units (display, printer, plotter, etc.). The object of this standard is to present terms and definitions, to list main characteristics of multichannel analyzers, technical requirements and test methods for the following parameters: - minimum and maximum signal pulse heights to be measured; · main error of the minimum and maximum measured signal pulse heights; · instability of the minimum and maximum measured signal pulse heights; · additional errors (or variations) of the minimum and maximum measured signal pulse heights; - channel width; · total error of the channel width; · instability of the channel width; · additional errors of the channel width; - zero point position; · offset; · instability of the zero point; · additional errors of the zero point; - operating range; - integral non-linearity; - differential non-linearity; - dead time; - maximum input pulse rate to be measured; - live time error; - non rectangular factor of channel profile; - system throughput.

ASTM G130-95 使用光谱辐射计校准窄带和宽带紫外辐射计的标准试验方法

1.1 This test method covers the calibration of ultraviolet light-measuring radiometers possessing either narrow- or broad-band spectral response distributions using either a scanning or a linear-diode-array spectroradiometer as the primary reference instrument. For transfer of calibration from radiometers calibrated by this test method to other instruments, Test Method E824 should be used. Note 1-Special precautions must be taken when a diode-array spectroradiometer is employed in the calibration of filter radiometers having spectral response distributions below 320-nm wavelength. Such precautions are described in detail in subsequent sections of this test method. 1.2 This test method is limited to calibrations of radiometers against light sources that the radiometers will be used to measure during field use. Note 2-For example, an ultraviolet radiometer calibrated against natural sunlight cannot be employed to measure the total ultraviolet irradiance of a fluorescent ultraviolet lamp. 1.3 Calibrations performed using this test method may be against natural sunlight, Xenon-arc burners, metal halide burners, tungsten and tungsten-halogen lamps, fluorescent lamps, etc. 1.4 Radiometers that may be calibrated by this test method include narrow-, broad-, and wide-band ultraviolet radiometers, and narrow-, broad, and wide-band visible-region-only radiometers, or radiometers having wavelength response distributions that fall into both the ultraviolet and visible regions. Note 3-For purposes of this test method, narrow-band radiometers are those with [delta][lambda] [and;lt;=] 20 nm, broad-band radiometers are those with 20 nm [and;lt;=] [delta][lambda] [and;lt;=] 70 nm, and wide-band radiometers are those with [delta][lambda] [>=] 70 nm. Note 4-For purposes of this test method, the ultraviolet region is defined as the region from 285 to 400-nm wavelength, and the visible region is defined as the region from 400 to 750-nm wavelength. The ultraviolet region is further defined as being either UV-A with radiation of wavelengths from 315 to 400 nm, or UV-B with radiation from 285 to 315-nm wavelength. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
