the mines had a life expectancy of 20 years after entering the mines.
It was two german doctors, Harting and Hesse, who brought this to

to lung cancer. But with their scientific knowledge the doctors could only
assume that the deaths were caused by the inhalation of arsenic. Later
studies between 1900 and 1940 found that the deaths were caused by
radiation in the mines.
The radiation the miners were exposed to would later be identified
as uranium. Uranium is a natural occurring e .....

A cetacean’s skin is free of sweat glands, oil glands, or hair, and feels much like smooth, wet rubber to the touch.
