Noxious earth energies are not visible – but they still have an effect on a person's body, in a similar way to X-rays - and the way that radio waves (also not seen) affect a radio or television.
Their effects on sleep, health, and school performance was carefully researched by Käthe Bachler of Austria on more than 11,000 people in over 3,000 apartments, houses, and work places in 14 countries, reported in her book 'Earth Radiation' ISBN 978-1-4357-0246-2.
The effects of these energies are well recognized in central Europe - even to the extent that in some countries professional reports are required before any schools or hospitals are built.
This book is an extract aimed at educating the English Speaking people about these Noxious Earth Energies - helping to avoid cancer and other major diseases, including the sudden deaths of infants.
