Abstract

Meaningful evaluation of physiological changes resulting from microwave/radiofrequency radiation (MW/RFR) exposure depends upon accurate dose level determination. Comparison of experimental results from different investigators also requires firm establishment of dose levels. Review of the current literature reveals considerable inconsistency in this area. Therefore, a reliable method of specific absorption rate (SAR) determination in living animals must be established. In this article, we propose a new procedure for SAR determination which does not interfere with other complementary measurements required during experimentation. This simple and reliable method utilizes both the rate of temperature increase during irradiation and the rate of cooling following exposure. Current experiments suggest that the proposed method is an effective technique for local and whole-body SAR determination and allows an accurate evaluation of MW/RFR bio-effects.

摘要

对微波/射频辐射（MW/RFR）暴露所导致的生理变化进行有意义的评估，取决于准确的剂量水平测定。不同研究者的实验结果进行比较，也需要明确确定剂量水平。对当前文献的回顾表明，该领域存在相当大的不一致性。因此，必须建立一种在活体动物中测定比吸收率（SAR）的可靠方法。在本文中，我们提出了一种新的SAR测定程序，该程序不会干扰实验过程中所需的其他补充测量。这种简单可靠的方法利用了辐照期间的温度升高速率和暴露后的冷却速率。当前的实验表明，所提出的方法是一种用于局部和全身SAR测定的有效技术，并且能够准确评估MW/RFR的生物效应。
