This International Standard is applicable to all assemblies designed to measure the ambient dose equivalent (rate) due to neutron radiation of energy up to 16 MeV, and which comprise at least: a) a detection assembly, which may, for example, consist of a detector probe for thermalised neutrons and an arrangement of moderating and absorbing media surrounding the detector; b) a measuring assembly with a display for the measuring result, which may be incorporated into a single assembly or connected by means of a flexible cable. NOTE Z If the Equipment consists of separate detector and measurement assemblies the cable between the two shall be that specified by the manufacturer. If the connection is by other means (e.g. radio waves, infrared) or other cables, it is necessary to apply additional requirements with respect to the specific media. The requirements given below pertain to assemblies as defined in the first paragraph. It is acceptable, however, to use assemblies, which do not meet the requirements below when such requirements are not deemed essential for a given purpose. In such cases, the requirements to be applied to the assemblies should be specified by agreement between the manufacturer and the purchaser, but the methods of determination of the characteristics of the assemblies should conform to this standard. No tests are specified in this standard for the performance requirements of the assemblies in pulsed radiation fields, and it is to be considered that an assembly designed to meet this standard may not be suitable for use in such fields. The object of this standard is to specify requirements for the performance characteristics of neutron ambient dose equivalent (rate) meters, and to prescribe the methods of testing in order to determine compliance with this standard. This standard specifies, for the assemblies described in the first paragraph, general characteristics, general test procedures, radiation characteristics, electrical, mechanical, safety and environmental characteristics, and also the identification certificate. Requirements and test procedures are also specified for the alarm performance of the dose equivalent (rate) meters, which are equipped with alarm provisions. NOTE Dose equivalent (rate) meters for neutrons have an energy dependence of ambient dose equivalent response, which may deviate considerably from unity. The response in realistic spectra encountered in workplace fields is such that the deviations in different energy ranges tend to neutralise each other. Consequently, the response in realistic fields is generally much closer to unity. ISO 12789 specifies a list of appropriate neutron sources having broad spectra suitable for the testing of such (rate) meters. Also work places may be specified by agreement between manufacturer and purchaser to be appropriate for testing when the spectral environment is well defined. Unconventional dose equivalent ratemeters, for example consisting of more than one detector probe, have recently become available. For such instruments, evaluation based on mono-energetic neutrons is not relevant. Also for those ratemeters, the above considerations may apply.

This International Standard is applicable to radiation meters and monitors designed for the direct measurement or the direct detection of surface contamination by alpha and/or beta radiation emitting nuclides and which comprise at least: - a detection assembly (comprising text deleted counter tube, scintillation detector or semiconductor detector, etc), which may be connected either rigidly or by means of a flexible cable or incorporated into a single assembly. - a measurement assembly. Some meters and monitors consist of detection assemblies and measurement assemblies where it is possible to separate the detector assembly and use alternative detection assemblies. Conformity with the standard can either be achieved by: All combinations of the detection assembly and the measurement assembly conforming to the requirements of this standard. or The detection assembly and the measurement assembly separately conforming to the relevant parts of this standard in isolation. NOTE The use of the latter criteria verifies conformance with this standard but does not infer that calibration of a particular combination of instruments is interchangeable with any other combination. The use of the latter criteria could allow a purchaser to use combinations of assemblies from different manufacturers with confidence. The standard is applicable to: - alpha surface contamination meters; - alpha surface contamination monitors; - beta surface contamination meters; - beta surface contamination monitors; - alpha/beta surface contamination meters; - alpha/beta surface contamination monitors. The latter two are equipment capable of determining alpha and beta contamination simultaneously and displaying the measurement of either: - Alpha (beta, alpha/beta) surface contamination meter An assembly including one or more radiation detectors and associated assemblies or basic function units, designed to measure alpha (beta, alpha/beta) surface emission rate associated with the contamination of the surface under examination. - Alpha (beta, alpha/beta) surface contamination monitor. This standard is also applicable to special purpose assemblies and to assemblies specifically designed for a surface of a particular nature. However, some of the requirements may need to be amended or supplemented according to the particular requirements applicable to such assemblies. If an assembly has been designed to carry out combined functions, it must comply with the requirements pertaining to these different functions. If, on the other hand, it has been designed to perform one function, and, in addition, it is also capable of carrying out other functions, then it must comply with the requirements for the first function, and it would be desirable for it to comply with requirements pertaining to the others. This standard is not applicable to radiation monitors or meters designed to measure or detect beta particles with Emax < 60 keV. The object of this standard is to lay down standard requirements and to give examples of acceptable methods, and also to specify general characteristics, general test conditions, radiation characteristics, electrical safety, environmental characteristics, and the requirements of the identification certificate for alpha, beta and alpha-beta contamination meters and monitors.

4.1 The radiochromic film dosimetry system provides a means of determining absorbed dose in materials. Under the influence of ionizing radiation, chemical reactions take place in the radiochromic film creating or enhancing, or both, optical absorption bands. Absorbance is determined within these radiation-induced absorption bands using a spectrophotometer or photometer (See 5.1.2).4.2 In the application of a specific dosimetry system, absorbed dose is determined by use of a calibration curve traceable to national or international standards.4.3 The absorbed dose determined is usually specified in water. Absorbed dose in other materials may be determined by applying conversion factors. This is discussed in ISO/ASTM Guide 51261.NOTE 1 - For comprehensive discussion of various dosimetry methods applicable to the radiation types and energies discussed in this practice, see ICRU Reports 14, 17, 34, and 35.1.1 This practice covers the procedures for handling, testing, and using a radiochromic film dosimetry system to measure absorbed dose in materials irradiated by photons or electrons in terms of absorbed dose in water.1.2 This practice applies to radiochromic film dosimeters that can be used within part or all of the specified ranges as follows:1.2.1 The absorbed dose range is 1 Gy to 100 kGy.1.2.2 The absorbed dose rate is 1 x 10-2 to 1 x 1013 Gy/s (1-4).1.2.3 The radiation energy range for both photons and electrons is 0.1 to 50 MeV.1.2.4 The irradiation temperature range is -78 to +60176;C.1.3 This practice applies to radiochromic films of various formats, including small pieces used to measure a single dose value, strips used for one-dimensional dose-mapping, and sheets used for two-dimensional dose-mapping. Three-dimensional dose-mapping may be achieved by proper placement of any of these formats.1.4 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.
