Description

The utility model relates to the field of dosimetric monitoring of various production facilities, and more particularly to devices for determining the exposure dose rate of γ-radiation of vertical and horizontal primary oil storage tanks before cleaning and dismantling.

A well-known household dosimeter containing a housing with a pulse generator, a counter and an indicator (1) placed in it.

The disadvantage of this dosimeter is the impossibility of its use in radiation examination of the state of vertical and horizontal primary oil storage tanks.

A known dosimeter comprising a housing in which a recording device, a pulse generator and a control panel are located (2).

The disadvantage of this dosimeter is the increased complexity of its use.

A known radiometer comprising a housing in which a detector, a pulse generator, a counter and an indicator (3) are placed.

The disadvantage of this radiometer is the inconvenience of its use in the inspection of oil tanks.

Known dosimeter DKG-07D "Drozd" for measuring the power of the ambient dose equivalent of gamma radiation (MAD) and the ambient dose equivalent of gamma radiation (AD) containing an unpressurized plastic housing, a battery with Geiger-Muller counters placed in it, a microcontroller and a liquid crystal scoreboard (4).

The disadvantage of this dosimeter is the inconvenience of use and the complexity of its operation, since the device should be at a distance of 0.1 m from the tank wall when taking sequential 7-10 research results at one point, while the device is in your hands, your hands are shaking, which in turn significantly reduces the objectivity and accuracy of measurements.

The purpose of creating a utility model is to reduce the complexity of operation, increase the convenience of work and objectify the accuracy and reliability of research.

This goal is achieved by the fact that the housing contains two mounting elements fixed to the housing and provided with clamps at the free ends, the clamps are made in the form of permanent magnets, or in the form of elastic vacuum suction cups, and the mounting elements are made telescopic and equipped with length-fixing screws.

Comparison of the proposed device with others known in the field of dosimetric control, showed its compliance with the criteria of a utility model.

The utility model is illustrated by graphic material, which shows the proposed device.

The proposed device includes a housing 1, which houses a pulse generator, counter and indicator (not shown). Two mounting elements are fixed to the housing 1, made in the form of telescopic rods 2, 3 and equipped with clamps 4 and 5 at the free ends, made in the form of permanent magnets or elastic vacuum suction cups. The lengths of the mounting elements are fixed with screws 6 and 7.

A device for measuring the power of the exposure dose of γ-radiation of vertical and horizontal tanks for storing primary oil is used as follows.

Using screws 6 and 7 set the length of the mounting elements 2 and 3.

When measuring the exposure dose rate of γ-radiation, the housing 1 should be located at a distance of 100 mm from the tank wall.

Using the clamps 4, 5, place the housing at a distance of 100 mm from the wall of the tank and carry out all the necessary measurements by a known method.

Remove the housing 1 from the tank wall, at the next measurement point and carry out the following measurements. The above steps are repeated around the perimeter of the tank.

Using the proposed device can improve convenience, reduce the complexity of the production of measurements and increase the objectivity and accuracy of measurements.

The device can and should be used when conducting radiation monitoring in the process of cleaning vertical and horizontal primary oil storage tanks.
