I think not. Allan H. Frey afrey@uu.net The fault, as is often the case in science, is in assumptions made before the study began, assumptions upon which the study is based. If the assumptions can not be shown to be true, then the conclusions are not valid. In their statistical study, it was assumed that the active agent in power line biological effects is the 60Hz sinusoidal wave. But there is substantial data and biological theory that indicate the primary active agent would be the transients that are found on power lines in varying forms to varying degrees in various places (Frey, 1994). A broad statistical study such as Linet et al's would tend to obscure such effects since data from areas where there are effective transients would be submerged in the mass of data from areas where there are not such transients. Epidemiological studies, and statistical studies in general, are quite useful for hypothesis generation. But they are not appropriate for drawing conclusions. Causality can not be shown. There are just too many unknown and uncontrolled factors operating in a large statistical study, as compared to wet biological experiments. This is particularly the case with magnetic fields as an agent, for it is not yet clear what parameters of the agent are of importance biologically. Is it appropriate to draw what may be life and death conclusions on the basis of one statistical study that is based on an assumption about what is the active agent, an assumption that can not be shown to be true? I doubt that many people would be willing to stake their life on one such study. Linet, M. et al.

Frey points to the possibility of transients as the metric underlying the earlier correlations. Another possibility is that the geomagnetic field may be a complementary factor, either because of cyclotron resonance or some other type of resonance interaction. In connection with this it appears that Denver was not one of the areas examined, which is puzzling considering the fact that data from the Denver vicinity was the impetus for such epidemiological studies. The media has characterized this study as the largest yet. For some time, I have had the feeling that funding for such studies would continue until the funders got the answer they wanted. Never mind the original objections to the Wertheimer and Savitz results--that epidemiological studies were "innately non-scientific" and did not prove anything. Now that the results are more in line with what is desired, we are subjected to newspaper and TV reports saying that this report is the final word. Nowhere does the media awaken the public to the fact that since Wertheimer's original 1979 results, there has arisen a wealth of (laboratory) evidence showing that ELF magnetic fields can have profound effects on living things. What in 1979 seemed inconceivable no longer appears improbable. Perhaps now that we have had, in the words of the media, the "final word", the rest of us can get on with the science underlying these ELF interactions, and, through the science, determine the consequences for human hazard.

The wire code configurations should however be a weak surrogate for electric fields, so these need a closer appraisal if our view of the importance of the electric field is to be supported. We are a little concerned to see that the distance from powerlines in the Linet study was limited to 150 feet (46 metres). There is a study by Ward et al. (1986) carried out by the UK National Grid showing that magnetic fields at over 100 metres distance from 400kV lines are still in excess of 0.2 microT, (and elsewhere the NGC indicates that at 100 metres the electric component may still exceed 30V/m). This may have the effect in the Linet study of omitting a number of leukaemia cases and thereby biasing the results towards the nul hypothesis. Comments welcomed.

Additional data sets are in the pipeline. Anyone is welcome to use this data, subject to a user license. The two data sets are: 001 Personal 24 Hour Emdex Pilot Project: Lynne Gillette and Doreen Hill, EPA, 1992. This project involved twenty volunteers who wore EMDEX C meters for 24 hours (including a typical work/school day) and logged information about their activities and possible sources of magnetic fields they encountered. 002 Household Appliance Magnetic Field Data: James R. Gauger, IITRI, 1983. The results of a non-comprehensive survey of the 60-Hz magnetic fields produced by common household appliances and tools are reported. Maximum magnetic field levels as a function of distance for 95 appliances of 27 basic types are characterized by measurement. Additional data sets in the pipeline include an office worker study completed at the University of Washington by Patricia Hogue and Michael Yost, as well as data from some of the other EMF RAPID Program Engineering Projects.
