An automated dosimetry system for microwave and thermal exposure of biological samples in vitro.

A waveguide exposure system with automated sample temperature measurement is described. This system provides on-line determination of the temperature profile over time of biological samples in vitro. It allows automated computation of the specific absorption rate determined from heating/cooling curves, uses minimally-perturbing thermometry, is biocompatible and can be used for measurements of both microwave and conventional heating.

Augmented transcription by electromagnetic field exposure: the experimental technique affects the measured transient response

Abstract The exposure of cells to relatively low intensity modulated microwaves or pulsed and low frequency electromagnetic fields results in a transient augmentation of transcriptional activity. One of the experimental methods for monitoring this involves measuring the incorporation of a radioactive tracer such as tritiated uridine into RNA. A previously described linear multi-step chemical reaction model that accounts for many of the principal features observed in such experiments is used to define a hypothetical “benchmark” system in terms of which a variety of protocols used in radioactive precursor uptake methods can be evaluated.

Biological Effects of High-Peak-Power Microwave Energy

At the Walter Reed Army Institute of Research, a research program designed to study the biological effects of non-ionizing radiation has focused on the effects of very short but high peak-power bursts of microwave energy. Cardiovascular, ocular and behavioral effects have been studied. This paper presents some of the behavioral effects that have been observed.
