The Theratron Junior delivered cobalt-60 radiation, a radioactive isotope of cobalt, for the treatment of cancer. Cobalt beam therapy uses deeply penetrating gamma radiation from a cobalt-60 source contained in the heavily reinforced tungsten head. These gamma rays are directed at malignant tumour sites.

In 1951, Canada was the first country to develop cobalt-60 radiation treatment. This cobalt therapy machine was manufactured by Atomic Energy of Canada Limited, a world leader in developing and selling nuclear technology for medical purposes.
