本标准描述了用于评估袖珍辐射检测仪器的设计和性能要求，以及用于快速检测和识别放射性物质的测试方法。 本标准中包含的性能要求旨在提供一种方法，用于验证这些仪器可靠检测辐射背景水平以上变化的能力，通知用户这些变化，并提供一种方法，以确定警报是否由可能需要进一步评估的感兴趣的放射性核素引起。 这些设备的主要目的不是提供剂量当量率的测量。然而，它们的指示可以提供一个合理准确的接触率近似值。它们也不是为了提供与ANSI N42中定义的放射性核素识别探测器相同级别的放射性核素识别。34.1 成功完成本标准中描述的试验不应被解释为能够识别所有环境中的所有放射性核素。

This standard describes design and performance requirements along with testing methods for evaluating radiation detection instruments that are pocket-sized and worn on the body for the purpose of rapid detection and identification of radioactive materials. The performance requirements contained in this standard are meant to provide a means for verifying the capability of these instruments to reliably detect changes above background levels of radiation, notify the user to these changes, and provide a means to determine if the alarm was caused by a radionuclide of interest that may require further evaluation. These devices are not primarily intended to provide a measurement of dose-equivalent rate. However, their indication can provide an approximate value of exposure rate that should be reasonably accurate. They are also not meant to provide radionuclide identification at the same level as radionuclide identification detectors defined in ANSI N42.34.1 Successful completion of the tests described in this standard should not be construed as an ability to identify all radionuclides in all environments.
