www.nrpb.gov.uk，下属一个部门Advisory Group on Non-Ionising Radiation (AGNIR)，专门从事类似的研究。

里面的结论有以下几点：
1、对静磁场有研究，但是仅限于3T以上的超强磁场（用于医学检查）
2、2001年发表文章，部分章节是电力线附近电磁场与癌症的关系（Recent large and well-conducted studies have provided better evidence than was available in the past on the relationship between power frequency magnetic field exposure and the risk of cancer. Taken in conjunction they suggest that relatively heavy average exposures of 0.4 µT or more are associated with a doubling of the risk of leukaemia in children under 15 years of age. The evidence is, however, not conclusive. In those studies in which measurements were made, the extent to which the more heavily exposed children were representative is in doubt, while in those in Nordic countries in which representativeness is assured, the fields were estimated and the results based on such small numbers that the findings could have been due to chance. In the UK, very few children (perhaps 4 in 1000) are exposed to 0.4 µT or more and a study in the UK, with much the largest number of direct measurements of exposure, found no evidence of risk at lower levels. Nevertheless, the possibility remains that high and prolonged time-weighted average exposure to power frequency magnetic fields can increase the risk of leukaemia in children. Data on brain tumours come from some of the studies also investigating leukaemia and from others concerned exclusively with these tumours. They provide no comparable evidence of an association. There have been many fewer studies in adults. There is no reason to believe that residential exposure to electromagnetic fields is involved in the development of leukaemia or brain tumours in adults. ）
也就是In the report it was concluded that laboratory experiments had provided no good evidence that extremely low frequency electromagnetic fields (EMFs) are capable of producing cancer, nor do human epidemiological studies suggest that they cause cancer in general. There is, however, some epidemiological evidence that prolonged exposure to higher levels of power frequency magnetic fields (50 hertz (Hz) in the UK) is associated with a raised risk of leukaemia in children (relative risk of approximately two).
关于和肺癌的关系Overall, the evidence that melatonin, and the timing and extent of light exposure, may affect breast cancer risk is intriguing but not conclusive. In aggregate, the evidence to date does not support the hypothesis that exposure to power frequency EMFs affects melatonin levels or the risk of breast cancer.
HPA的建议是In 2004, the National Radiological Protection Board (NRPB - now the Radiation Protection Division of the HPA) recommended the adoption in the UK of guidelines from the International Commission on Non-Ionizing Radiation Protection (ICNIRP) for limiting exposures to ELF EMFs3,4. This advice remains extant. ICNIRP is an independent body recognised by the World Health Organization (WHO) that provides advice on the health effects of exposure to non ionising radiations. Guidelines for ELF EMFs are based on the plausible and coherent scientific evidence related to effects on the central nervous system and other excitable tissues. The review of scientific evidence that underpinned this recommendation was published as Documents of the NRPB Volume 15 No 35.
In addition, the uncertainties in the underlying evidence base led NRPB to recommend in its 2004 document that the Government should consider the need for further precautionary measures in respect of exposure of people to ELF EMFs. In doing so, it should note that the overall evidence for adverse effects of ELF EMFs on health at levels of exposure normally experienced by the general public is weak. The least weak evidence is for the exposure of children to power frequency magnetic fields and childhood leukaemia5. The Government welcomed this advice from NRPB.
换而言之，还是赞同ICNIRP的标准，也就是我国超高压变电现在采用的标准！
