FILM DOSIMETER FOR NEUTRON THERAPY

第二阶段研究的主要目的是开发廉价的，自我的， 用于监测剂量的即时胶片， 放射治疗 一种新型的合成物， 用X射线、伽马射线、电子和中子照射将 合成了 将通过涂覆 在透明塑料基底上的组合物。 所述制剂和 将优化膜的制备工艺。 的影响 可以使用伽马射线，X射线， 电子和中子，将被确定。 的不确定性和 将确定膜的灵敏度。 光束数据采集和 将对验证膜进行实地测试。

The main aim of the phase II study is to develop inexpensive, self- developing, instant films for monitoring dose, and verification of radiation therapy. A novel class of compositions which develop color upon irradiation with x-ray, gamma ray, electrons and neutrons will be synthesized. Radiographic films will be prepared by coating the compositions on a transparent plastic substrate. The formulations and the processes for preparation of the films will be optimized. The effect of several parameters, such as dose, dose rate and energy of gamma ray, x-ray, electrons and neutrons, will be determined. The uncertainty and sensitivity of the films will be determined. The beam data acquisition and the verification films will be field tested.
