医用直线加速器感生放射性冷却时间的检测
Study of Induced Radioactivity and Measure of Cooling Time to the Medical Linear Accelerator
摘要
Abstract
Objective Study the relationship between the induced radioactivity and the cooling time of medical linear accelerator by the detection of induced radioactivity. Methods When the X-ray energy of the accelerator were 6MV, 10 MV and 15MV, use radiation detection apparatus and 451P inspection to detect the induced radioactivity of 200cGy radiation dose within 0-30 minutes. Analyze and make statistical analysis test data. Results When the X-ray energy of accelerator increases, the induced radioactivity incr eases, and the cooling time is extended accordingly. Conclusion X-ray energy and cooling time affect the induced radioactivity levels of Medical linear accelerator.关键词
