A new method is proposed for generating the alternating input signal for an ionization chamber. The equipment consists of a rotating ionization chamber, a radiation source, and a standard object. The ionization chamber has at its center a stationary collector, which is the axis of rotation of a cylindrical screen to which the radiation source is attached. The radiation going directly into the chamber is screened. The radiation directed outside the chamber is alternatively reflected either from the object tested, or from the standard, and falls on the collector electrode. The ionization current arising has a half-wave form, the amplitude of which depends on the properties of the tested or the standard object. The indicator connected to the output of an a-c amplifier is calibrated directly in units of the controlled variable and indicates the derivation between the properties of the object and the standard.
