Combining near- and far-field exposure for an organ-specific and whole-body RF-EMF proxy for epidemiological research: a reference case.

A framework for the combination of near-field (NF) and far-field (FF) radio frequency electromagnetic exposure sources to the average organ and whole-body specific absorption rates (SARs) is presented. As a reference case, values based on numerically derived SARs for whole-body and individual organs and tissues are combined with realistic exposure data, which have been collected using personal exposure meters during the Swiss Qualifex study. The framework presented can be applied to any study region where exposure data is collected by appropriate measurement equipment.

Measurement setup and protocol for characterizing and testing radio frequency personal exposure meters.

Body-worn radiofrequency electromagnetic field (RF-EMF) personal exposure meters (PEMs) have been increasingly used for exposure assessment in epidemiological research. However, little research on the measurement accuracy of these devices is available. In this article a novel measurement setup and a measurement protocol are presented for characterizing and testing PEMs.

Radiography in the United States Army during World War II: Part II.

This is the second of two articles highlighting Army radiography during World War II. Topics center around the certification of Army radiographers, rank structure, scope of service, adverse working conditions, improvisations, and contributions by Arthur W. Fuchs.

Radiography in the United States Army during World War II: Part I.

This is the first of two articles highlighting Army radiography through World War II. Topics concentrate on a few important military and civilian events between wars (1918-1941), such as the Army's contributions in (classifying) radiographic knowledge and escalating x-ray commercialization. Peacetime objectives, the mobilization effort, personnel and training, and how WACs and civilians contributed are discussed also.
