Reciprocity law failure was measured for four brands of medical x-ray films exposed with intensifying screens. Three of the films are green light-sensitized for use in combination with green light-emitting rare-earth screens. These films showed larger reciprocity failure effects than one conventional blue-sensitive film, Dupont Cronex-2. Development conditions had a small effect on reciprocity failure. As part of the investigation, a detector was constructed with a response that accurately monitors the light emission from the double screen-cassette combination over a wide range of x-ray photon energies.
对四种与增感屏一起曝光的医用X光胶片进行了互易律失效测定。其中三种胶片对绿光敏感，用于与发射绿光的稀土增感屏配合使用。与一种传统的蓝敏胶片杜邦Cronex - 2相比，这些胶片显示出更大的互易律失效效应。显影条件对互易律失效的影响较小。作为调查的一部分，构建了一种探测器，其响应能在很宽的X射线光子能量范围内准确监测双层增感屏暗盒组合的发光情况。
