Reading between the Lines

Abstract

In the last 100 years mankind has, for the first time in evolution, incorporated artificial electromagnetic fields and radiations into the built environment. Thirty years passed after the discovery of X‐rays before any exposure limits were imposed on these “ionizing” radiations, and the exposure limits have steadily fallen ever since, as early researchers found out to their cost just how dangerous these unseen energies are. Now scientists are asking whether chronic exposure to the non‐ionizing electromagnetic fields ubiquitous in homes, offices and factories, and which also emanate from powerlines, TV and radio masts and radar, are also likely to cause ill health. Sets out the present position in the fierce debate over claimed ill health effects from weak environmental electromagnetic fields, assesses the evidence, and gives practical advice for the structural engineer or surveyor. This is a subject to which professional bodies must give serious consideration within the near future, on the basis of this and other independent advice.
