摘要

252

Cf近距离放射治疗主要用于宫颈癌的腔内放射治疗，在放射治疗的同时势必对附近器官产生辐射危害，因此评价宫颈癌患者在放疗过程中其他器官的辐射损伤是必要的。本文以某医院

252

Cf宫颈癌的放射治疗为参考，通过

252

Cf在空气、水中剂量场分布理论计算和实际检测，对比子宫、直肠、膀胱、卵巢等器官的耐受剂量限值，给出了在宫颈癌治疗过程中，除靶器官子宫会受大剂量照射出现损伤外，直肠、膀胱、卵巢等器官也受较大辐射危害。为了减少宫颈癌患者的辐射损伤，经计算给出了不同源活度情况下的最佳照射时间。

Abstract

Background

The

252

Cf brachytherapy is mainly used for cervical cancer endovascular radiotherapy.

Purpose

Radiation therapy will inevitably cause radiation damage to nearby organs. Therefore

it is necessary to evaluate the radiation damage of cervical cancer patients during radiotherapy.

Methods

This article is based on the radiation therapy of

252

Cf cervical cancer in a hospital

and theoretical calculations and practical tests of dose field distribution in air and water by

252

and compared with the tolerance limits of uterus

rectum

bladder

ovary and other organs.

Results

By comparison

it is concluded that in the process of cervical cancer treatment

organs such as the rectum

bladder and ovary are also affected by large radiation in addition to damage caused by high doses of irradiation.

Conclusion

In order to reduce the radiation damage of cervical cancer patients

the optimal irradiation time under different source activity was calculated.
