He was elected a Fellow of the Royal Society in 1965. His candidacy citation read: " Distinguished for his applications of physics to medical sciences. He was responsible for the use of fluorescence spectroscopy in the collaborative study of carcinogenic agents in coal-tar which led to the discovery of the activity of 3:4 - benzopyrene. He was among the first to measure gamma-radiation in "r" units. His precision measurements have stood the test of time. He is recognised as the leading authority in the United Kingdom on the applications of radiation dosimetry to medical radiology and to the problems of radiation hazards."
