Unprotected experiments in the U.S. in 1896 with an early X-ray tube (Crookes tube), when the dangers of radiation were largely unknown.[1]The history of radiation protection begins at the turn of the 19th and 20th centuries with the realization that ionizing radiation from natural and artificial sources can have harmful effects on living organisms.

On January 27, 1896, Wright produced an X-ray photograph, barely a month after Wilhelm Röntgen's seminal paper On A New Kind Of Rays was published on December 28, 1895. This was the first X-ray image produced in the country. [9] He contributed numerous scientific papers, chiefly on astronomical and electrical subjects, to various publications.
Researchers had already discovered that X-rays could kill bacteria by 1896. The predominant theory at the time was that cancer was some kind of parasitic infection. Louis Charles Émile Lortet and Philibert Jean Victor Genoud tried to kill tuberculosis in infected guinea pigs using X-rays from March to June 1896 in the same city of Lyon. [7] [3]
