船用射频电磁场防护服的研制

Researches on RF electromagnetic field-protective clothes for crew

目的研制船用射频电磁场防护服。方法筛选并改进屏蔽材料，设计制造新型防护服样衣，进行防护效能测量评价实验。结果所选用屏蔽材料在10MHz至20GHz频率范围内屏蔽效能为56．8～34．2dB，防护服在30MHz至18GHz频率范围内整体防护效能为15～45dB，适于船员防护射频电磁场时穿着。结论新研制的防护服基本达到了设计要求，对船舶射频电磁场有较好的防护效果。

Objective To study RF electromagnetic field-protective clothes for crew. Methods Shield materials were selected and improved, and the new type of protective clothes was designed and made. The protection effect was measured and evaluated. Results Within the frequency scope of 10 MHz -20 GHz, the shield effect of the chosen shield material were 34.2 - 56. 8 dB; within the frequency scope of 30 MHz - 18 GHz, the whole protective effect of the protective clothes were 15 -45 dB. The protective clothes can protect the crew from RF electromagnetic radiation. Conclusions The new protective clothes can fulfil the basic design requirements. It has good protective effect against RF electromagnetic radiation.
