This paper evaluates the airborne radioactive concentration, dose-rate of internal and external exposure as well as purification mode and operating time of ventilation systems in reactor building.
The combination of external beam irradiation with brachytherapy may decrease the dose of external irradiation, so the late radiation complication may be reduced.
采用外照射与腔内近距离放射治疗可以降低外照射剂量，减轻部分放射并发症。

The second was nasal synechia(33/131), the chosen factors were total dose of external irradiation, intracavitary irradiation and medicamentous rhinitis.
