摘要
在慕尼黑工业大学的研究反应堆中进行了各种临床前试验,以确定平均能量为2 MeV的U-235转炉板产生的快中子的性质。实验使用了两个特定的光束,分别表示为RENT I和RENT II (RENT代表反应堆中子疗法)。RENT II是未经修饰的光束,剂量率为65 rd/min,在有机玻璃模体的2厘米深度中伽马污染接近50%。在RENT I中,在用2.5 cm的铅过滤光束后,伽马成分降低到25%,而总剂量率降低到22 rd/min。
The RENT-project: radiobiological results and planned clinical application.
Various preclinical tests have been performed to determine the properties of fast neutrons of a mean energy of 2 MeV produced by an U-235 converter plate in the research reactor of the Technical University of Munich. Experiments have been carried out using two specific beams denoted as RENT I and RENT II (RENT stands for Reaktor Neutron Therapy). RENT II is the unmodified beam with a dose rate of 65 rd/min and a gamma-contamination of nearly 50% in 2 cm depth of a perspex phantom. In RENT I the gamma-component is reduced to 25% after filtration of the beam with 2.5 cm lead, whereas the total dose rate is reduced to 22 rd/min.
