Description

Radiation exposed dose rate measuring instrument with a separability

The present invention relates to a radiation exposure dose rate meter, and more particularly, to a radiation exposure dose rate meter configured to allow the guide tube and the radiation detector to be mutually fastened and detached to facilitate partial repair and replacement in the event of component failure or breakage. will be.

In general, in nuclear power plants and other medical and industrial facilities using radioactive isotopes or generators, it is necessary to constantly monitor radiation exposure and exposure levels in the working environment of workers.

As a device for measuring radiation dose rate of workers in the use of radioisotope and launch line generators, it is possible to measure the radiation dose rate of beta gamma radiation at high level, in particular, at a distance of more than a certain length from the user to enable remote measurement. An apparatus which is required is illustrated in FIG. 1 of the accompanying drawings, which is a general measuring device for the measurement of the dose rate of such high level radiation exposure.

That is, as shown in the figure, a high-level radiation dose dose rate meter is generally composed of a multi-stage type that is used to be folded or folded at a predetermined length, and the configuration is composed of a radiation detector 10 for detecting radiation in a measurement space, and one side of the radiation detector ( 10) is coupled to the multi-stage configured guide tube 20 is variable by the plurality of connecting members, the other side of the guide tube 20, the display window 32 and the function selection switch 34 is provided and the radiation The exposure dose detected by the detector 10 is composed of a main body 30 directly displayed to the user, and a handle 40 connected to the rear end of the main body 30. In addition, a protective cap 12 for protecting the outside of the radiation detector 12 is provided separately.

The guide tube 20 is usually composed of nine stages, the through-hole is formed through the transmission cable (not shown) in the center, and when taking out all the connecting members, so as to allow a distance measurement of about 5m It is.

The main body 30 is for interface with a user, and a circuit board (not shown) is mounted therein, and a signal detected from the radiation detector 10 is transmitted to the display window 32 of the guide tube 20. The exposure dose rate is transmitted in the form of a numerical value or the like. In addition, the function selection switch 34 is basically provided with functions such as measurement radiation level selection, battery check and power on / off.

In addition, the handle 40 has a built-in battery for supplying power in the main body 30.

However, the conventional radiation exposure dose rate meter as described above is partially repaired in case of breakage of the guide tube 20 because the radiation detector 10 installed at the end of the guide tube 20 is integrally coupled with the guide tube 20. Even if the other parts operate normally, the measuring instrument itself cannot be used, which is economically very inefficient.

Accordingly, the present invention was devised to solve the above problems, and an object of the present invention is to periodically repair the components by separately separating them when the guide tube and other parts of the radiation exposure dose rate meter are damaged. And to provide a radiation dose dose rate meter which can be used more efficiently and economically by inspection.

The present invention is configured as follows to achieve the above object. That is, the present invention is a radiation detector for detecting a high level of radiation, a protective cap that protects it from the outside, a guide tube composed of a multi-stage guide tube having a variable length with a front end coupled with a radiation detector, coupled with a rear end thereof, and detected by a radiation detector In the radiation dose dose rate measuring device comprising a main body displayed to the user, the handle is connected to the rear end of the main body, the detector fixture is provided to be detachable from the radiation detector, the guide is detachably connected to the guide tube The tube fixture is characterized in that it comprises a detector fixture coupled to each other to be fastened and detachable.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
