[PAR] [TLE] William Henry Bragg [SEP] Sir William Henry Bragg (2 July 1862 – 12 March 1942) was a British physicist, chemist, mathematician and active sportsman who uniquely shared a Nobel Prize with his son William Lawrence Bragg – the 1915 Nobel Prize in Physics: ""for their services in the analysis of crystal structure by means of X-rays"".  The mineral Braggite is named after him and his son.  He was knighted in 1920. [PAR] [TLE] Bragg–Gray cavity theory [SEP] According to the Bragg–Gray cavity theory, the ionization produced in a small cavity within an irradiated medium or object is related to the energy absorbed in that medium as a result of its radiation exposure.  It was developed in 1936 by British scientists Louis Harold Gray, William Henry Bragg, and William Lawrence Bragg.
