Abstract

A formula for the OER in a mixed field of neutrons and gamma rays (Hall, 1972a; 1972b) is given .... Our results, calculated from track structure theory (Katz and Sharma, 1973) and secondary particle-energy spectra in tissue from these neutrons (Caswell and Coyne, 1973; Dennis, 1972) are within 5 per cent of the values of O_mix found from the Hall formula, when that formula is supplied with calculated values of R_n, O_n, and O_γ, at appropriate survival levels. Our calculations suggest that the Hall formula may be used with confidence for neutrons of different energies and for pions.
