Description

yen in the form of, for example, a pin and a spiral antenna, and the microwave detector 4 can be placed inside the removable part of the connector 2.2.

A device for indicating the level of electromagnetic radiation of electro, magnetic and radiotherapy devices operates as follows.

Medical personnel are provided with indicating devices that are either placed in a workwear pocket or placed on a stand at a distance set from the apparatus. Before starting work, the operator servicing the equipment includes an indication device and power from an autonomous power source 5 is supplied to the elements of the device. An electromagnetic field acts on the sensors 3.1,3.2 and is converted by them into an electrical signal. Depending on the frequency spectrum of the visualized field, the indicated electrical signal is processed and detected either in the channel containing the source repeater 7, the bandpass filter 8, the linear detector 9, the low-frequency amplification stage 10, or in the channel containing the microwave detector 4, the high-amplification stage 14 frequency. From the output of these channels, the low-frequency signal is fed to one of the inputs of the comparator 11, the potential of the other input of which is rigidly fixed. The level of the compaired signal is set by switch 12. When the specified level of electromagnetic radiation is exceeded and, accordingly, when the value of the comparator threshold corresponding to this level is exceeded, the signal at the output of comparator 11 is sufficient to ignite the LED (visualizer 13). Based on the information received about the electromagnetic field, measures are taken to protect personnel from harmful effects.
