本课只做一件事：用 5 道题检验「辐射与极端环境」，并把错的那几道归到具体原因上。
Test Radiation & Extreme Environments with five items and trace every miss to a specific cause.
本课不涉及：不出新知识点——只检验前四课学过的内容。
Not covered here: No new material — only what lessons 1 to 4 covered.
本课目标 | Learning objectives
- 5 题至少答对 4 题，并说清每题依据
- 把错题归为「词不懂 / 问句读错 / 依据不足」三类之一
- 说出本块学到的三条可迁移结论

五题复盘 | Five-question recap
选出答案并提交，查看解析与依据。/ Pick an answer, submit, and read the rationale.
1. 电离辐射三原则是？
The ionizing triad is?
2. 点源距离从 2 m 退到 4 m，剂量率？
Moving from two to four metres from a point source changes dose rate how?
3. WBGT 的组成不包括？
WBGT does NOT include?
4. 电焊 UV 的旁人防护靠？
Bystander protection from welding UV relies on?
5. 热习服一般需要？
Acclimatization typically takes?
错因归类 | Sort your misses
- 拿气温当 WBGT → 湿度与辐射热改变分级，排班跟着错Using air temperature as WBGT → humidity and radiant heat change the category, and work/rest schedules go wrong accordingly
- 焊工戴面罩即结案 → 旁人电光性眼炎是被漏掉的暴露Welder wears a face shield, case closed → bystanders' arc eye (photokeratitis) is the missed exposure
- 距离控制被低估 → 平方反比是三原则里性价比最高的一项Distance control underrated → the inverse-square rule is the most cost-effective of the three principles
接下来学什么：下一块（Day 207–211）继续 Domain 6：人体工效与疲劳管理——顺时针排班、微休息与手传振动。
Next block (Days 207–211), still Domain 6: ergonomics and fatigue management — forward rotation, micro-breaks and hand-arm vibration.
