光量子疗法中圆面紫外灯辐照度的定量研究

本文根据光辐射的基本概念，应用数学物理方法，导出了血液辐射治疗仪中带反射罩的紫外线灯的辐照度的计算公式，用ＸＴ－Ａ型紫外光功率计，对ＸＬ－２００型血液辐射治疗仪进行实测，经过计算分析，定出了公式中的待定参数，并应用公式对各实测点进行计算对比，计算值与实测值符合得非常好，发现紫外灯辐射度并简单的指标衰减，为近距离辐照剂量的估算提供了一个有价值的公式，从而将光量子疗法中关于辐照剂量问题的研究定量化。

QUANTITATIVE STUDY ONIRRADIANCE OF A ROUNDULTRAVIOLET LAMP IN PHOTOTHERAPY

In this paper a formula has been derived for calculating the irradiance of the ultravlolet lamp with thereflector used in the blood radiation treat meter.Through the meastirement of the XL-200 blood radiation treatmeter by using XT-Aultraviolet light power meter,the parameters used in this formula have been exactly calcu-lated out And the formula coincides with the expetrimental value and it showse that the relationship between theirradiance of ultraviolet lamp and the distance is not simply the form of exponentlal attenuation. And the formulawhich provides a valuable method of calculating the irradiation at a close distance will make advances in the studyof irradiation.
