作者提出了低温核供热堆辐射防护安全准则的建议，即①要求半径５０ｋｍ范围内加权人口不超过１０６；②禁区半径为２５０ｍ；③限制发展区半径２ｋｍ；④低温核供热堆正常运行期间，由于放射性向环境释放所致公众个人剂量（全身或有效）不应超过０．１ｍＳｖ／ａ，集体剂量不超过１００ｍａｎ·Ｓｖ／ａ；⑤低温核供热堆事故期间，公众个人剂量不超过５ｍＳｖ，集体剂量不超过１０００ｍａｎ·Ｓｖ；⑥低温核供热堆正常运行期间，放射性流出物（气体、液体）的释放量不应超过国标ＧＢ６２４９规定值的２／５；⑦热网水中的放射性活度不应超过０．３７Ｂｑ／Ｌ；⑧建议应急状态分为三级，即应急待命、厂房应急和场区应急。
The author put forward the suggestion on the safety guidelines for radiation protection of low-temperature nuclear reactor. ①The weighted population within 50km radius should not exceed 106; ② The radius of the forbidden zone should be 250m; ③ The radius of restricted development zone should be 2km; ④ During the normal operation of low- , Due to radioactive release to the environment due to the public personal dose (whole body or effective) should not exceed 0.1mSv / a, the collective dose does not exceed 100man · Sv / a; ⑤ low temperature nuclear reactor accident, the public individual dose does not exceed 5mSv , The collective dose does not exceed 1000man · Sv; ⑥ during normal operation of low-temperature nuclear heating reactor, the release of radioactive effluents (gas, liquid) should not exceed 2/5 of the national standard GB6249; ⑦ radioactivity Should not exceed 0.37Bq / L; ⑧ recommended emergency state is divided into three levels, namely emergency standby, plant emergency and field emergency.
