The author persues earlier considerations regarding a quantitative evaluation of the usefulness against risks of radiological examinations, with a detailed discussion of the radiological and diagnostic problems. The possibilities of accurately quantifying degrees of urgency are discussed in practical terms, particularly for new forms of investigation in widespread use. In addition to a consideration of the usefulness and risks based on days gained or lost in the life of the patient, it is suggested that the cost of the examination should also be borne in mind. A model is illustrated by a number of examples. Finally, certain psychological problems are outlined which are concerned with the valuation and use of protective measures and with subjective estimates of risks involved.
作者继续探讨早期关于放射检查益处与风险定量评估的考量，并详细讨论了放射学和诊断问题。从实际角度讨论了准确量化紧急程度的可能性，特别是对于广泛应用的新型检查形式。除了基于患者生命中获得或失去的天数来考虑益处和风险外，还建议应考虑检查成本。通过多个例子说明了一个模型。最后，概述了一些与防护措施的评估和使用以及所涉风险的主观估计相关的心理问题。
