Abstract

The measures detailed in the 'Code of Practice for the Safe use of Beryllium at JET' are summarized. JETs (Joint European Torus') policy of segregating beryllium related work into BeCAs (beryllium controlled areas) has ensured that the general workplace (torus hall, assembly hall, etc.) remain free of airborne and surface contamination, and hence no safety precautions have had to be adopted in these areas. There have been no beryllium incidents leading to airborne concentrations in excess of 0.2 mu gm/sup -3/ outside of any BeCA. Aerial discharges of beryllium have generally been undetectable and have never approached the limit of 0.01 mu gm/sup -3/. No cases of acute or chronic beryllium intoxication have been diagnosed; some minor cuts have been sustained in BeCAs (no contamination of the wound was found on samples) and no treatment has been required beyond conventional first-aid procedures. In-vessel work has continued to be possible despite high levels of surface contamination and variable air concentrations, but the logistics support for in-vessel operation has increased very noticeably as a result of beryllium.<>

铍在JET的安全性

“安全使用铍的工作守则”详列各项措施的摘要。jet(欧洲联合环)将与铍有关的工作隔离到BeCAs(铍控制区)的政策确保了一般工作场所(环厅、装配厅等)不受空气和表面污染的影响，因此在这些区域无需采取安全预防措施。在任何BeCA外，没有发生导致空气中铍浓度超过0.2 μ gm/sup -3/的事故。铍的空中排放通常无法检测到，也从未接近0.01 μ gm/sup -3/的极限。没有急性或慢性铍中毒的病例被诊断;在BeCAs中有一些轻微的割伤(样品上没有发现伤口污染)，除了常规的急救程序外，不需要任何治疗。尽管存在高水平的表面污染和多变的空气浓度，但船上作业仍然可以继续进行，但由于铍的存在，船上作业的后勤支持大大增加了。
