This simple, no-nonsense guide to EMFs and how to reduce their harmful effect presents information in an easy-to-follow handbook style. EMF levels are graded using a star rating system, high-level items are highlighted, and practical tips are given in step-by-step, bullet point form. Electrical wiring and appliances, overhead power lines, machinery, photocopiers, cell phones, radio masts, TVs, tube trains, x-rays and laser beams are among the hundreds of everyday items that are now known to give off high levels of microwave radiation. Electromagnetic fields (EMFs) can be biologically active and capable of making changes to the structure of human and animal cells which are exposed to them. Long-term exposure is believed by an increasing number of scientists and environmentalists to be connected to tumors, fertility problems, behavior and mood changes, and concentration and memory loss; and also to affect melatonin production and impair our immune system repair mechanisms.
