The testees were not allowed to use their mobile phones for 24
hours. Afterwards the researchers took blood from a finger tip and
earlobe. Then the testees had to use a phone for 20 seconds.
Immediately after that the researchers took blood again and ten
minutes later again.
The result: after using the mobile phone it was clearly visible
that the red blood cells lumped together in 'rolls of coins'.
Also ten minutes afterwards the 'rolls of coins' still were clearly
visible. The lumping raises the risk of thrombosis.
In 1927, when colloid chemist Ernst Muth first discovered that
red blood cells exposed to radio frequency waves (at levels far
less powerful than permitted today by the FCC) are forced to line
up in chains resembling strings of pearls.
