ABSTRACT
The authors describe a device for measuring the dose field in the beam section of ionizing radiation. The device consists of an immovable bench mark detector and the two detectors: a movable one and a photodiode placed on a tele- and separately movable carriage. The device affords defining the correspondence of radiation and light fields.

Radiation Dosage , Radiometry/instrumentation , Radiation, IonizingABSTRACT
Three varieties of complete control over dosimetric devices are reviewed. In these devices, use is made of combined detectors consisting of scintillators and semi-conductors. The control is effected by means of scintillator illumination from a stabilized light source via an edge-lighted panel.

Radiometry/instrumentationABSTRACT
A set of devices including a contactless contourograph and cartograph was developed. They ensure a high accuracy of plotting topographic anatomical maps of the patient's body transverse section, taking into account tumor size parameters, for the quality planning of radiation therapy.

The paper describes a digital apparatus capable of measuring the duration of X-radiation within the range of 0.001-10.0 s with an error of 2%. The apparatus is used for exposure control in X-ray units having four- and six-pulse circuits.

Radiography/instrumentation , HumansABSTRACT
Dosimetry systems for evaluating radiation parameters over the X-ray diagnostic range and for documenting patient exposure doses are analyzed. In the general case the hardware for recording the complete set of parameters is proposed, and simplified versions for particular problems are also given.
