Abstract

The World Health Organization (WHO), the International Commission on Non-Ionizing Radiation Protection (ICNIRP), WHO's scientific collaborating centres (including the UK's National Radiological Protection Board (NRPB)) and over 50 participating Member States are participants of WHO's International EMF Project. As part of WHO's health risk assessment process for extremely low frequency fields (ELF), this workshop was convened by NRPB to assist WHO in evaluating the potential health impacts of electrical currents and fields induced by ELF in molecules, cells, tissues and organs of the body. This paper describes the process by which WHO will conduct its health risk assessment. WHO is also trying to provide information on why exposure to ELF magnetic fields seems to be associated with an increased incidence of childhood leukaemia. Are there mechanisms that could lead to this health outcome or does the epidemiological evidence incorporate biases or other factors that need to be further explored?

Main findings

Describes the process by which WHO will conduct its health risk assessment for extremely low frequency (ELF) fields, based on a workshop convened to assist evaluation of potential health impacts of ELF-induced currents and fields in biological systems. Notes that WHO is examining why ELF magnetic field exposure appears associated with increased childhood leukaemia incidence, including whether mechanisms exist or whether epidemiological evidence may reflect biases or other factors.

Outcomes measured

Potential health impacts of ELF-induced electrical currents and fields in the body
Childhood leukaemia incidence (association with ELF magnetic field exposure)

Limitations

Appears to describe a risk assessment process/workshop rather than reporting new empirical health effect results.
No quantitative exposure metrics, sample size, or study results are provided in the abstract.
