Abstract—

One of the important properties of industrial radiographic films that determine the clarity of the resulting image is granularity. In the technical specifications for any industrial radiographic film, the manufacturer is obliged to provide information on granularity in addition to other characteristics such as sensitivity to radiation and contrast, and the companies that attest radiographic films must evaluate it. This is required by the international standard ISO 11699-1: 2008. The granularity value (among other characteristics) determines the belonging of the radiographic film to a certain class, and, consequently, the possibility of using the film in X-ray or gamma tetsing of certain objects. To assess the granularity, specific equipment and adherence to the technology of this process, regulated by ISO 11699-1: 2008, is required. The article provides information on the assessment of granularity by means of the developed stand with dummies of the optical system and the data collection system in automatic and manual modes. The developed stand was used to assess the granularity of the D5 (Agfa) radiographic film. The obtained experimental data coincide within the permissible range with the data specified in the certificate of conformity to international standards.

根据 ISO 11699-1 确定射线照相胶片的粒度

摘要-

决定最终图像清晰度的工业射线照相胶片的重要特性之一是粒度。在任何工业射线照相胶片的技术规范中，制造商有义务提供有关粒度以及辐射敏感性和对比度等其他特性的信息，并且证明射线照相胶片的公司必须对其进行评估。这是国际标准 ISO 11699-1: 2008 所要求的。 粒度值（以及其他特性）决定了射线照相胶片属于某个类别，因此，确定了在 X 射线或伽马射线中使用胶片的可能性某些对象的测试。为了评估该过程的粒度、特定设备和对技术的遵守，ISO 11699-1: 2008 是必需的。本文提供了有关通过开发的带有光学系统和数据收集系统的假人的支架在自动和手动模式下评估粒度的信息。显影后的支架用于评估 D5 (Agfa) 射线照相胶片的粒度。获得的实验数据与国际标准合格证书中规定的数据在允许范围内一致。
