In this paper, the authors analyze the case study of the recovery of an orphan source of ⁶⁰Co inside a maritime cargo full of metal wastes in the Italian Harbor of Genova carried out by the Italian Fire Fighters. Orphan radioactive sources or Radiological Dispersal Devices are a critical security issue in large geographical areas, and they result in a safety concern for people who may become accidentally exposed to ionizing radiation. The abandonment of orphan sources can usually be related to three factors: human errors, cost reasons (in order to avoid the payment of disposal procedures), or malevolent purposes (like the production of dirty bombs). The present data concern the nuclear safety measures implemented during the recovery event and the pool of procedures carried out in order to reduce the risks for the involved harbor operators. Following data collection and analysis, an important lesson about the management of such events and scenarios can be learned.

在本文中，作者分析了一个⁶⁰的孤儿源的恢复的案例研究。由意大利消防员在热那亚的意大利港内装满金属废物的海运货物。在大地理区域中，孤立的放射源或放射分散设备是一个关键的安全问题，它们对可能不小心暴露于电离辐射中的人们造成安全隐患。遗弃孤儿的来源通常与三个因素有关：人为错误，成本原因（以避免支付处置程序的费用）或恶意目的（例如生产脏炸弹）。目前的数据涉及在恢复事件期间实施的核安全措施以及为减少所涉港口经营者的风险而执行的程序集。在数据收集和分析之后，
