“…Even though it is likely that this association does exist in the French pediatric population it may be either a direct individual association or, alternatively, reflect the effect of some other unknown individual or Commune characteristics, which are related to residential sun exposure and influence the incidence of this particular group of ALL. This is not the case for the increased incidence of children leukemia that has been observed in France in the close vicinity of nuclear power plants [35] or high voltage power lines [3]. Both increased incidences are very localized spatially and cannot explain the trend association found in this study.…”

“…Several genetic diseases and polymorphisms [1], and non-genetic exposures (including H B E B factors. Some factors related to early immune stimulations and environmental exposures (pesticide use at home and, for AL, extremely low frequency electromagnetic fields) are also suspected [2,3]. Solar ultraviolet (UV) radiation, UVA (315 -400 nm) and UVB (280 -315 nm), exposures are ubiquitous with marked gradients within and between countries.…”

This study addresses the associations between residential UV exposure at diagnosis and the incidence of types and subtypes of CHM, by age and gender, in France, over a long period, on the fine scale of the 36,326 Communes that constitute mainland France. Methods The 9,082 cases of acute leukemia (AL) and 3,563 cases of lymphoma diagnosed before the age of 15 years from 1990 to 2009 were provided by the French National Registry of Childhood Hematological Malignancies. The incidence of CHM was calculated by Commune, year, age and gender and expressed as the standardized incidence ratio (SIR). UV data from 1988 to 2007 were extracted from the EUROSUN database. Results The annual daily average UV exposure of the children ranged from 85.5 to 137.8 J/cm 2 . For each additional 25 J/cm 2 there was a significant increase in precursor B-cell acute lymphoblastic leukemia (PBC-ALL) in children aged less than 5 years (SIR: 1.18; 95%CI: 1.10-1.27). Further analysis of PBC-ALL in the young children suggested a better fit of models with a threshold, with the risk increasing above 100 J/cm 2 , for which the SIR was 1.24 (95%CI: 1.14-1.36) for a 25 J/cm² increase. The results remained stable in analyses stratifying by deprivation index or degree of urbanization of the Communes. Conclusion The study suggests that higher residential UV exposure may be positively associated with a higher incidence of PBC-ALL in early childhood.

The California Power Line Study is a case-control study investigating the relation between residences near transmission lines and risk of childhood leukemia. It includes 5788 childhood leukemia cases and 5788 matched primary controls born between 1986 and 2007. We describe the methodology for estimating magnetic fields at study residences as well as for characterizing sources of uncertainty in these estimates. Birth residences of study subjects were geocoded and their distances to transmission lines were ascertained. 302 residences were deemed sufficiently close to transmission lines to have non-zero magnetic fields attributable to the lines. These residences were visited and detailed data, describing the physical configuration and dimensions of the lines contributing to the magnetic field at the residence, were collected. Phasing, loading, and directional load flow data for years of birth and diagnosis for each subject as well as for the day of site visit were obtained from utilities when available; when yearly average load for a particular year was not available, extrapolated values based on expert knowledge and prediction models were obtained. These data were used to estimate the magnetic fields at the center, closest and farthest point of each residence. We found good correlation between calculated fields and spot measurements of fields taken on site during visits. Our modeling strategies yielded similar calculated field estimates, and they were in high agreement with utility extrapolations. Phasing was known for over 90% of the lines. Important sources of uncertainty included a lack of information on the precise location of residences located within apartment buildings or other complexes. Our findings suggest that we were able to achieve high specificity in exposure assessment, which is essential for examining the association between distance to or magnetic fields from power lines and childhood leukemia risk.

Although it is difficult to imagine life without electricity, there are compiling confirmations show that exposure to magnetic fields correlated electricity and radio frequencies pose magnificent hazards to human health. The most economist method to transfer electricity from power generation stations to users is by measures of high power transmission lines, buoyed by big transmission towers. The cables laced between the towers radiate magnetic and electric fields. In this research study, the magnetic field at ground level under 400 kV network lines extended in residential places have been conducted in two ways, mathematical calculation and practical measurement then the obtained results analyzed and compared with the international standards reference values. the reason of chose this type of transmission line is frequently using. The results indicate that they fall within the safe limiter commended by the World Health Organization. the strength of radiation increasing with high of sea level and moisture ratio because of air ionization Keywords: High voltage transmission lines, magnetic field, negative health effect.
