In the 30-s of the twentieth century the German scientist – professor Hartmann found out that the Earth is covered with bands of radiation with an unknown nature. The bands of radiation form specific net and have a width of about 20 cm. The distance between them is 2 metres in the north – south direction and 2.50 metres in the direction of east-west .
This radiation was found to have adverse impact on the human organism. The radiation above the intersection points on those bands turned to be especially harmful. They were named geopathogenic spots. The net itself was named after its discoverer - Hartman's net.
There are different ways for neutralization of the geopathogenic radiation, but undoubtedly the most effective way is the usage of reduced models of the Cheops pyramid.
