Tesla noted the hazards of working with his circuit and single-node X-ray-producing devices. In his many notes on the early investigation of this phenomenon, he attributed the skin damage to various causes. He believed early on that damage to the skin was not caused by the Roentgen rays, but by the ozone generated in contact with the skin, and to a lesser extent, by nitrous acid. Tesla incorrectly believed that X-rays were longitudinal waves, such as those produced in waves in plasmas. These plasma waves can occur in force-free magnetic fields.
What did tesla incorrectly believe about x-rays? what did tesla attribute skin damage to? what did Tesla think nitrous acid contributed to?  what did tesla note the hazards of working with?  where do plasma waves occur?  At first what did Tesla think was the main cause of damage to skin cells when they were exposed to X-rays? What did Tesla mistakenly believe X-rays were? Where are longitudinal waves found? Where can Tesla's theories as to what caused the skin damage be found?
