For those who were arguing about the issue of rising leukaemia in children Michel Coleman's paper at the Leukaemia Conference seems to settle the issue: It is rising.
For those arguing against any link with electrification, Sam Milham's paper seems pretty conclusive too: It is associated.
I copy Sam's abstract below, to encourage this thread to visit the Leukaemia Conference site and read such things for themselves.

A peak in childhood leukemia, ages two through four, emerged de novo in the 1920's in the United Kingdom and slightly later in the United States (US). In 1920, half of urban and rural US non-farm homes had electric service compared to 1.6% of farm homes. Electrification in US rural and farm areas lagged behind urban areas until 1956. In recent years, childhood leukemia has been associated with residential magnetic fields. Using US Census Bureau data for residential electrification by state, single year of age leukemia mortality and population data ages zero through four, states with over 75% of electrified residences in 1928-1932 showed increasing leukemia mortality for single years of age 0-4, while states with electrification levels below 75% showed a decreasing trend with age (p<0.009). During 1949-1951, all states showed a peak in leukemia mortality at ages 2-4. At ages 0-1, leukemia mortality was not related to residential electrification levels. At ages 2-4, there was a 24% (95% confidence interval (CI), 8%-41%) increase in leukemia mortality for a 10% increase in percent of homes served by electricity. Common acute lymphoblastic leukaemia (cALL) is solely responsible for the peak of childhood leukemia between ages two and five.
The authors conclude that the childhood leukemia peak is due to electrification and that 75% of all childhood acute lymphoblastic leukemia and 60% of all childhood leukemia may be preventable[B/].
