    Cobalt Blues describes the development of the first cobalt unit in the United States and the man behind it, Leonard Grimmett. Conceptually conceived before World War II, it only became possible because of the development of nuclear reactors during the war.   There is a great deficit and disparity in the number of teletherapy units across the world. Only four of low- and middle-income countries (LMICs) are currently equipped with an adequate number of machines, and more than 9, machines will be needed by 1 Linear accelerators (linacs) and cobalt units can be used to meet this demand for teletherapy Cited by: 4.

      Working principle An external sealed source of cobalt 60is used in teletherapy unit as a source of intense gamma radiation for the treatment of a variety of cancers. Cobalt 60 is used as tracer that is injected into the body, then cobalt 60 source emits gamma rays, that’s scanned by machine 6. Parts of cobalt T60 machine 1. Head 2.   COBALT • In , Cobalt 60 teletherapy was first put to clinical use in London 6. The main reasons for its suitability for teletherapy • Availability of relatively small • High specific activity • Sources that minimise the beam penumbra • Relatively long half-life ( years) • Almost monochromatic high-energy photon emission.

    Cobalt may be substituted for radioactive cesium chloride for many applications (see the discussion in Chapter 5), although as much as twice the shielding thickness may be required for a source that achieves the same dose rate, and the half-life of cobalt is shorter ( years for cobalt versus 30 years for cesium), thus lowering.

Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt to treat conditions such as ing in the s, cobalt was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient's body to kill tumor tissue.
