Development of Radiation Therapy 1902,the treatment of skin cancer using radiation was reported 1920,orthovoltage therapy machine invented. The first Cobalt 60 machine was produced in Canada. 1958,the first electron accelerator was built in Britain 1968,the modern linear accelerator was built in USA by Varian brothers 1990's,modern time,3D RT due to the computer technique
