Abstract:

Paired ionization chambers with nominal volumes of 0.05 cc are in use at the Armed Forces Radiobiology Research Institute to measure neutron and gamma components of depth doses in steady-state and pulsed TRIGA fields. Cavity chamber theory is employed to obtain quantitative estimates of neutron and gamma dose sensitivities of a chamber with a tissue-equivalent plastic wall filled with a tissue-equivalent gas and magnesium chamber filled with CO2. The uncertainties in these estimates have been propagated through the paired chamber equations and result in the following uncertainties in measured dose components in a field where the neutron to gamma dose ratio varies from 0.1 to 15.
