An X-ray of Tutankhamun's skull, the arrow pointing to a possible cause of death 1905; Heinrich Ernst Albers-Schoenberg used the radiological method to examine an Egyptian mummy. He discovered that there was a substance in the thorax and pelvis which had most likely been placed there for mummification purposes.
It was found that x-rays were only capable of producing a cure in certain cases of the basal cell type of epithelioma and exceedingly unreliable in malignant cancer, not making it a suitable replacement for surgery. In many cases of treatment, the cancer recurred after a period of time. X-ray experiments in pulmonary tuberculosis proved useless.
When she saw the picture, she said, "I have seen my death." [5] The first use of X-rays under clinical conditions was by John Hall-Edwards in Birmingham, England, on 11 January 1896, when he radiographed a needle stuck in the hand of an associate. On 14 February 1896, Hall-Edwards also became the first to use X-rays in a surgical operation. [6]
After 893 days in the hospital, he was declared dead after sepsis caused by complications and infections of a radiation ulcer on the subject's back. [55] The disposal team consisted of 24 men who were restricted to a maximum of 40 seconds worth of exposure (max. 20mSv) each while transferring the canisters to lead -lined drums.

The source can be in the vicinity of the body or can be on the skin surface. The level of health risk is dependent on duration and the type and strength of irradiation. Penetrating radiation such as gamma rays, X-rays, neutrons or beta particles pose the greatest risk from an external source.
