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 252 Cf 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 γ‐ray dose response independent of energy over a major part of the 252 Cf spectral range, while transmission measurements have demonstrated that the liquid causes little perturbation of the radiation field.
