On the application of a liquid dielectric ionization chamber to ²⁵²Cf dosimetry

Our investigations of an iso octane filled liquid dielectric ionization chamber indicate that this dosimeter is well suited for the measurement of dose distributions at distances close to ²⁵²Cf interstitial implant sources. Initial research has shown that such an instrument provides good discrimination between the radiation components of a mixed field and possesses excellent sensitivity. Calculations indicate that iso octane will yield a neutron and ray dose response independent of energy over a major part of the ²⁵²Cf spectral range, while transmission measurements have demonstrated that the liquid causes little perturbation of the radiation field.
