+# 辐射环境历史数据查询
+
+> 可查询自 2023-08-25 起的国家核安全局辐射环境监测数据历史数据
+
+数据来源：[国家核安全局](https://nnsa.mee.gov.cn/) - [辐射环境监测数据](https://data.rmtc.org.cn/gis)
+
+视频版说明(B站)：[<链接>]()
+
+
+
+## 目录结构
+
+- 后端服务：backend
+
+- 前端页面：html
+
+- 数据采集：spider
+
+- 数据库表结构：sql
+
+
+
+## 项目环境
+
+数据库使用 MySQL 8.0，逻辑上讲 MySQL 5.7 版本应该也能使用，但我没有测试过。
+
+后端和数据采集端需要在 node 环境下运行，初次使用需要 `npm i` 安装依赖。
+
+
+
+## 一些说明
+
+这个项目代码写的比较烂，毕竟只是一个数据采集工具，除非官方网站更新，否则后期应该不会改动太多。大家如果要看代码，可以带着审视的眼光来看，相信大家能够写出比我的更优雅的代码。
+
+
+
+## 免责声明
+
+本站仅记录自 2023-08-25 起的辐射环境监测数据历史值，不对数据来源真实性做保证，数据使用权请查阅上方数据来源自行获取，仅通过技术层面保存监测数据历史记录，方便学术研究使用。
