He firmly states why he believes some of the epidemiological studies are flawed. After evaluating the data he set out to debunk the theorized link between magnetic fields and wire code along with the correlations between magnetic fields and cancer rates. After analysis on the startling results of a study done in Sweden in 1992, Ashley developed an answer that was almost to obvious. The Swedish study established that children living within 50 meters of bulk power transmission lines were five times more likely to have developed childhood leukemia. The answer is electric fields.
Electric fields decay with distance similarly to magnetic fields.
None of the previous epidemiological studies looked at or measured peak electric fields outside the houses. In his concluding paragraphs, he suggests that you watch where you walk. This situation is found throughout the US, wherever suburbs have been built up near older 115-230 kV lines. He strongly urges that epidemiological studies include more significant measures of exposure and the peak intensity of electric fields outside homes. Mr. Ashley admitted that not enough is known about power lines and cancer risk to answer some basic questions.
