Studies on health and electromagnetic fields

Here are some comments on the review by Robyn M Lucas, Michael H Repacholi & Anthony J McMichael in the June 2006 issue of the Bulletin.

This is a very good review. I will comment on some statements from the text. I will also refer to two WHO projects regarding studies on health and electromagnetic fields (EMFs) in which I am currently involved.1,2

"Skin cancer (is) caused by excessive exposure to UVR." This is not necessarily true; another hypothesis is that the increase is caused by reduced efficiency of the skin-damage repair process.3

"There is evidence that the incidence of skin cancer is beginning to plateau in some countries." It is important to note that for cutaneous malignant melanoma (CMM) it is the incidence among younger age cohorts that has levelled off; this is yet not so for older cohorts. This indicates an environmental change some 50 years ago, and that we will have to wait until 2025 before all age cohorts flatten out, thus giving a stable age-standardized level.3–5

"The age-standardized incidence of CMM in southern and eastern Europe are now increasing sharply in all age groups." The change from the 70 to 87–108 MHz band for FM radio in eastern countries around 1990 onwards is expected to give increasing rates of CMM, as we noticed in Nordic countries from around 1955–1960 onwards. In the Nordic countries, the body-resonant FM radio was introduced starting in 1955.
