When X-rays were discovered by Röntgen in 1895 Dawson Turner was one of the first to appreciate their possible application in medicine. He built an early X-ray apparatus in his home at 32 George Square, Edinburgh. On 5 February 1896 he demonstrated X-rays at a meeting of the Edinburgh Medico-Chirurgical Society.In 1901 he became Physician in Charge of X-Rays at Edinburgh Royal Infirmary remaining in this role until ill-health caused his partial retirement in 1911 from which time he became "Extra Electrician" until his full retirement in 1925. He was one of the first, in 1902, to use X-rays in the treatment of cancer. In 1911 he was one of the earliest recorded persons using radium to treat lymphosarcoma. His surgical colleague Alexis Thomson inserted an aluminium case, which enclosed a glass tube containing radium bromide, into the tumour below the clavicle. Turner, over the next few days, exposed the involved lymph nodes above the clavicle to radium bromide contained in a second tube. There was no trace of the tumour when the patient was examined at three months or again at one year after treatment.
His Edinburgh address until retiral due to ill-health was 37 George Square. The building was demolished by Edinburgh University in the 1960s to make way for George Square Library. Early in his career he had lost two fingers of his left hand as a result of exposure to radiation which had also resulted in the loss of an eye. For the last years of his life he did not enjoy good health and his symptoms were presumed to result from radiation exposure. He died of radiation related cancer at Godalming in Surrey on Christmas Day 1928. His is one of the 14 British names of the 169 included on the Monument to the X-ray and Radium Martyrs of All Nations erected in Hamburg, Germany in 1936. In 1931 Edinburgh Royal Infirmary erected a memorial plaque to his memory in the radiology department.
