This invention relates to x-ray energy. Actually a chain of

technology, namely for devices for source 5 and resistor 6 with a scale

measurement of radiation parameters simulates the curve of the spectral sensitivity of the x-ray emitter, the detector 2, given

These can be used when checking 5 in FIG. 2. Scheme 8 dividing makes the control of x-ray equipment, there is a division of the signal of the detector 2,

The purpose of the invention is to increase the dot-amplified amplifier 7 on the signal

To measure the dose rate and / or the correction resistor 6, the dose is proportional to the ratio of the detector response in FIG. 1 shows a diagram of the device per unit dose rate, in order to measure the parameters of the radiation, as a result of which, at the output of the x-ray deletion output circuit 8, a signal is formed, which is proportional to, in FIG. 2 - curve spectral dose rate, the value of which

detector 2, a dividing circuit 8, to the input-formula of the invention which is connected to an amplifier output — a device for measuring parameter 7 and a control signal for correcting the radiation output of the x-ray resistor 6, as well as a measuring radiator, containing two distances 9, connected to the output of circuit 8 de-tector with different spectral Chuv. laziness, In this embodiment, the gadget included to meet designed to measure the power of a Friend to a friend, a null organ, and a variable doses. When measuring the dose, an additional measuring resistor with a scale of efno introduces an integrator between the measured energies, with one output The telem 9 and the dividing circuit 8. The measuring resistor is grounded, The device works as follows: the second output is connected to one input. at once. null organ to another entrance of which When detectors 1 and 2 are installed in 35, one of the detectors is connected, and the control x-ray field in the return terminal of the resistor is connected to currents flowing towards the second detector are produced, and the means of measuring each other. Moving the control of the dose and / or dose rate, including the output of the measuring resistor, the correction resistor from the scale4, the operator sets zero of the effective energies, about 1 L and zero organ 3.
