【摘要】 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。更多还原

【Abstract】 The X-ray dose profile produced by HT-6M Tokamak covered in operation was studied. The measurement shows that X-ray is a continuous spectrum covered rather wider energy range, and its intensity varies with place and direction. The dose on the vacuum vessel is larger and ranges from 2.3102mSv to 1.6 104mSv, while the dose in the hall, outside two meters from the torus surface, is 0-1 .8102mSv. The number of photon with energy below 500. keV is about 85 percent of the total. The information given here provides necessary basis of protection and safety estimation for normal device operation.更多还原
