Roy Bentley obituary

My father Roy Bentley, who has died aged 87, was a medical physicist whose career spanned almost the entire history of the speciality.

The son of Frank, a chartered accountant, and his wife, Stella (nee Barker), who helped out in the family hosiery and glove business, Roy was educated at West Bridgford grammar school, Nottingham, and Birmingham University. His PhD, awarded in 1955, focused on the uptake of radioisotopes in fats and laid significant ground for the use of markers in medical imaging.
