Description

The invention relates to devices for monitoring and protecting the environment, in particular to devices for radiometric observation, indication and decontamination of the area during radiation accidents of radiation-hazardous objects.

A device for reducing radioactive contamination and indicating radioactivity [1] is known, which provides an indication of radioactivity and decontamination of the accident site at radiation hazardous facilities. The disadvantage of this device is the inability to measure radiation conditions, its dependence (activation) on other devices and its stationary location on radiation-hazardous facilities.

Closest to the claimed is a device for radiometric monitoring and decontamination of the area [2], which is used in a radiation accident of a radiation-hazardous facility. This device contains a complete radiometric device that measures all types of radiation. The disadvantage of this device is that the decontaminating substance is sprayed at a height and, reaching the surface of the earth, it may not cover the zone of radioactive contamination due to various weather conditions (e.g. wind) and terrain conditions (e.g. forest, tall trees), i.e. . the device may not fulfill its function. In addition, there is no indication of ionizing radiation, which makes it difficult to determine the reliability of deactivation. The disadvantage of the radiometric device assembly is that, being in the accident area in a radioactively contaminated area, it does not deactivate it.

The objective of the invention is the creation of a device that quickly monitors the radiation situation and provides the measurement of all types of radiation (alpha, beta, gamma and neutron radiation) of radioactive substances (RS) in the area of a radiation accident of a radiation hazardous object (ROO), provides fixation of the center of radioactive contamination in a solid stable environment, indication of the type and intensity of radiation in the area of a radiation accident of a radiation-hazardous object and deactivates the area in the area of radiation av arias without the participation of personnel.

The above problem is solved due to the fact that the device contains an unmanned aerial vehicle (UAV), a device for monitoring the radiation situation, a control device, combined into a single design assembly. Moreover, an active element, an indicator module, is introduced into the radiometric device assembly in the radiation monitoring device [2] between the radiometric sensor and the parachute. This provides operational monitoring of the radiation situation, measurement of alpha, beta, gamma and neutron radiation of radioactive substances in the area of the radiation accident ROO, fixation of the source of radioactive contamination in a stable solid medium, an indication of the type and intensity of ionizing radiation in the area of the radiation accident and decontamination in area of radiation accident and protection of personnel from radiation contamination.

New features in the present invention is the combination in one device of measuring instruments, indications of all types of ionizing radiation and decontamination of radioactive substances.

The invention is illustrated by the drawing, which shows the actual device for radiometric observation, indication and decontamination of terrain I, consisting of an unmanned aerial vehicle 7, a device for monitoring the radiation situation 2, a control device. 3. The radiation monitoring device II consists of a triggering device (reset) of a set of radiometric devices 4 and a radiometric device assembly 5. The radiometric device assembly III consists of a radiometric sensor 6, indicator module 7, parachute 8 of the parachute activation device 9.

In operation, a device for radiometric observation, indication and decontamination of the terrain works as follows.

In the initial position, the device is stored in the immediate vicinity of a radiation hazardous facility.

In the event of a radiation accident, the device is promptly deployed to its working position, prepared for operation and the aircraft is launched. Moving at the altitude of the radioactive cloud, the radiation monitoring device measures the radiation situation, the activation (reset) device resets radiometric devices to the site of the radiation accident. The parachute trigger device opens the parachute, the radiometric device drops to the ground. After landing, the parachute is shot, thus forming a hole for the exit of the decontamination mixture. A radiometric sensor measures the radiation environment and transmits data to the UAV. If radioactivity is detected above the set limit, the indicator module starts up. Indication of ionizing radiation and decontamination of the accident site is carried out by spraying a deactivating polymerizable indicator mixture under pressure. There is a decontamination of the contaminated area, fixing the focus of radioactive contamination and an indication of the intensity of ionizing radiation.

The technical result of the use of the present invention is to increase the efficiency and reliability of obtaining information about the radiation situation by measuring and indicating all types of ionizing radiation of radioactive substances in the accident area of a radiation-hazardous facility and the operational implementation of measures to improve the radiation situation by fixing the focus of radioactive contamination and decontamination of the area without participation staff.
