本文件直接适用于脉冲持续时间为0.1 ms至10 s的脉冲X射线。该范围涵盖了发表时用于医学诊断的整个范围。一些规格也可以适用于短得多的脉冲；一个例子是一个脉冲的空气比释动能。这种脉冲可以例如通过X射线闪光单元或高强度飞秒激光器产生。其他规格不适用于短得多的脉冲；一个例子是空气比释动能率的时间相关行为。由于技术原因，这是不可测量的，因为没有合适的仪器可用，例如对于由飞秒激光器产生的脉冲。 本文件规定了用于校准和测试辐射防护剂量计和剂量率计对脉冲辐射的响应的参考脉冲辐射的特性。在这一点上，它只关心单个脉冲的特性。单脉冲是剂量计最难测量的。确定重复脉冲的剂量比连续辐射更容易，但仍然更困难，即剂量计在测量重复脉冲时的性能介于这些极端之间。辐射特性包括以下内容: 脉冲的空气比释动能率的时间相关行为； 脉冲期间X射线管高电压的时间相关行为； 所述辐射束的横截面积内的空气比释动能率的均匀性； 一个辐射脉冲的空气比释动能； 辐射脉冲的空气比释动能率； 重复频率。 本文件没有定义新的辐射质量，而是使用现有ISO和IEC标准中规定的辐射质量。相反，该文件给出了用于脉冲辐射的参数和用于指定辐射质量的连续辐射的参数之间的链接。它没有规定脉冲辐射场的具体值或一系列值，而仅规定了校准剂量计和剂量率计以及根据所述参数确定其响应所需的相关脉冲辐射参数的那些限值。 根据ISO 4037（所有部分），使用转换系数确定关于体模相关量的脉冲参数。这是可能的，因为使用了现有ISO和IEC标准中规定的辐射质量。 给定的参考脉冲X射线设备的特征在于满足本文件规定的全部质量标准和要求的参数范围。因此，并非所有参考脉冲X射线设备都可以产生覆盖相同参数范围的脉冲。

This document is directly applicable to pulsed X-radiation with pulse duration of 0,1 ms up to 10 s. This range covers the whole range used in medical diagnostics at the time of publication. Some specifications can also be applicable for much shorter pulses; one example is the air kerma of one pulse. Such a pulse can be produced, e.g. by X-ray flash units or high-intensity femtosecond-lasers. Other specifications are not applicable for much shorter pulses; one example is the time-dependent behaviour of the air kerma rate. This cannot be measurable for technical reasons as no suitable instrument is available, e.g. for pulses produced by a femtosecond-laser.

This document specifies the characteristics of reference pulsed radiation for calibrating and testing radiation protection dosemeters and dose rate meters with respect to their response to pulsed radiation. At this point, it is only concerned with the characteristics of single pulses. Single pulses are the most difficult for dosemeters to measure. Determining the dose for repeated pulses is easier, but still more difficult than for continuous radiation, i.e. the performance of the dosemeters when measuring repeated pulses lies between these extremes. The radiation characteristics includes the following:

1. time-dependent behaviour of the air kerma rate of the pulse;
2. time-dependent behaviour of the X-ray tube high voltage during the pulse;
3. uniformity of the air kerma rate within a cross-sectional area of the radiation beam;
4. air kerma of one radiation pulse;
5. air kerma rate of the radiation pulse;
6. repetition frequency.

This document does not define new radiation qualities but uses those radiation qualities specified in existing ISO and IEC standards. Instead, this document gives the link between the parameters for pulsed radiation and the parameters for continuous radiation specifying the radiation qualities. It does not specify specific values or series of values for the pulsed radiation field but specifies only those limits for the relevant pulsed radiation parameters that are required for calibrating dosemeters and dose rate meters and for determining their response depending on the said parameters.

The pulse parameters with respect to the phantom-related quantities were determined using conversion coefficients according to ISO 4037 (all parts). This is possible as the radiation qualities specified in existing ISO and IEC standards are used.

A given reference pulsed X-ray facility is characterized by the parameter ranges over which the full specifications and requirements according to this document are met. Therefore, not all reference pulsed X-ray facilities can produce pulses covering the same parameter ranges.
