At Cambridge he studied the Natural Science Tripos, and was awarded first class honours in Part I in 1930 and Part II in 1931, graduating with a Bachelor of Arts (BA) degree. Having specialised in physics in Part II, he was advised by Lord Rutherford to return to Birmingham to undertake his clinical training.

During this research he discovered the possibility of using the radioactive isotope cobalt-60 to treat cancer.

In 1946, he returned to England and became Professor of Radiotherapeutics at the University of Cambridge. He was also appointed Director of the Radiotherapeutic Centre at Addenbrooke's Hospital. During this appointment he became internationally known for his work on the treatment of cancer by irradiation. In 1957, he was appointed Regius Professor of Physic, succeeding Sir Lionel Whitby.
