Nó đã được ghi nhận trước đó rằng phóng xạ có thể tạo ra các hiệu ứng sinh học. Xung quanh chuyển giao thế kỷ, một số thí nghiệm đã được thực hiện, trong đó, sẽ được đặc trưng hiện nay là nguy hiểm và liều lĩnh. Nó được tìm thấy rằng bức xạ ion hóa có khả năng phát triển bỏng da và có thể gây ra tóc rơi ra ngoài. Năm 1899, Stenbeck và Sjogren từ Thụy Điển sử dụng bức xạ để loại bỏ một khối u từ mũi của bệnh nhân. Điều này cho thấy rằng. | Chapter 10 Radiation and Health. Large Doses It was noted earlier that radiation can produce biological effects. Around the turn of the century a number of experiments were carried out which would be characterized today as dangerous and foolhardy. It was found that ionizing radiation was capable of developing skin burns and could cause hair to fall out. In 1899 Stenbeck and Sjogren from Sweden used radiation to remove a tumor from the nose of a patient. This showed that radiation in large doses could be used to kill cancer cells. In the early years when radium was used for treatment the sources were made in the form of capsules or small tubes. The procedure for radium treatment was either to use a large source of radium teletherapy or to use a number of small sources for brachytherapy. In the latter case paraffin wax was often used and formed to suit the part of the body to be irradiated. Small needles of radium were then sealed into the wax. This procedure gave a good dose distribution when skin ailments and tumors were treated. The general view at that time was that the radiation from radioactive sources was healthy and was a good treatment for most sufferings. Figure next page shows an advertisement from 1913. Some people made good money by producing radioactive drinking water. A number of small towns in middle Europe such as Badgastein Baden-Baden Marienbad and Karlovy Vary had radioactivity in their water and were considered to be healthy places. With the use of a jar and some radium salt Figure the water was saturated with radon when radium disintegrated. The belief was that by drinking this water you received curative radioactivity. In those days like today some 2003 Taylor Francis 116 Radiation and Health RADIUM THERAPY The only scientific apparatus for the preparation of radio-active water in the hospital or in the patient s own home. This apparatus gives a high and measured dosage of radio-active drinking water for the treatment of gout .
