Research Interests

The Human Radiation Effects Group is funded by the charity CHILDREN WITH LEUKAEMIA to research environmental causes of childhood leukaemia, with emphasis on non-ionising radiation. Evidence suggests that power frequency magnetic fields suppress the production in the pineal gland of the important hormone and natural anti-cancer agent melatonin and this may explain the adverse health effects associated with magnetic field exposures. High voltage powerlines also emit corona ions which may help explain an apparent increased risk of childhood leukaemia up to 600 metres away in the UK. Professor Henshaw is a member of the co-ordinating committee of the Government Stakeholder Advisory Group for EMF (SAGE).
