本文对HT-6M托卡马克装置在运行时所产生的X射线剂量,能量进行了测量研究。真空空环表面剂量较大,变化范围:2.3×10~2～1.6×10~4mSv;大厅剂量变化范围(距环表面2m外)0～1.8×10~2mSv。测量表明,X射线能量是比较宽的连续谱,并且随测量位置和方向的不同而有一定变化。经实验估计能量≤500keV的X射线约占85%左右。本文给出的剂量数据为装置正常运行提供了防护和安全评价的依据。
In this paper, the X-ray dose and energy generated by the HT-6M tokamak device during operation were measured. The dosage of the vacuum ring is larger, the range of variation is 2.3 × 10 ~ 2 ~ 1.6 × 10 ~ 4mSv, and the range of the dosage of the hall is 0 ~ 1.8 × 10 ~ 2mSv. The measurement shows that the X-ray energy is a relatively wide continuous spectrum and varies with the position and orientation of the measurement. The experiment estimated that the energy ≤500keV X ray about 85%. The dose data presented in this paper provides the basis for the protection and safety evaluation of the normal operation of the device.
