The presence of radioactive materials in scrap metal has been detected relatively often in recent years. As a result of an accidental melting of a 137Cs source in a Spanish steel mill (Acerinox) in 1998, the national authorities, the involved private companies, and the main trade unions drafted a protocol for prevention of and responding to such events ("Spanish Protocol"). The Protocol was signed in 1999. The number of subscribing companies is 90. The Protocol is a voluntary agreement defining the radiological surveillance of scrap metal and its products and the duties and rights of the signatories. From the effective date of the Protocol to December 2004, 461 pieces of ferric scrap were detected including sources of radiation and contaminated metal. Four melting incidents have happened in different companies.
近年来，废旧金属中放射性物质的存在被相对频繁地检测到。1998年，西班牙一家钢铁厂（阿塞里诺克斯公司）意外熔化了一个铯-137源，作为结果，国家当局、相关私营公司和主要工会起草了一份预防和应对此类事件的议定书（“西班牙议定书”）。该议定书于1999年签署。签署议定书的公司有90家。该议定书是一项自愿协议，规定了对废旧金属及其产品的放射性监测以及签署方的义务和权利。从议定书生效日期到2004年12月，共检测到461块含铁废料，其中包括辐射源和受污染金属。不同公司发生了四起熔化事故。
