These Hartmann bands of energy (single crossing) do not constitute much of a health hazard unless they were going through the area of the head in the bed site, which can cause insomnia, depression and migraine type headaches. Crossing any other part of the body in the vast majority of cases would not produce any discomfort. However, when this line of radiation is in combination with A/C pulsed magnetic fields around and above 70 nT (nano Tesla) or crosses over the outside edge of a subterranean water course it can produce a depleted state of energy leading to Chronic Fatigue Syndrome, and an opportunistic environment for the growth of abnormal cells leading to cancer.
