Problems solved by technology

There are many disadvantages in the general method, and there is no mature measurement system and device. Specifically, the dose rate meter is used to measure the dose rate at different positions, but it is impossible to accurately obtain the coordinates and punctuation points of the current measuring point in the entire three-dimensional space. , which brings great inconvenience to the follow-up radiation field calculation and source term inversion work, so new measurement methods and devices are urgently needed to achieve accurate and fast three-dimensional dose field measurement

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] This embodiment is aimed at the problem that the existing measuring means of the radiation field in the three-dimensional space cannot accurately obtain the coordinates and punctuation points of the current measuring point in the entire three-dimensional space, which brings great inconvenience to the subsequent calculation of the radiation field and the inversion of the source term. Furthermore, a measurement method and measurement device for space gamma dose rate radiation field are proposed. The measurement method and measurement device can accurately, quickly and conveniently measure the dose rate data of spatial position coordinates.

[0022] See attached figure 1 As shown, the device for measuring the spatial gamma dose rate radiation field in this embodiment includes a total station, a dose rate meter, and a tablet comput...

Abstract

The invention provides a space gamma dose rate radiation field measuring method and device, and the method comprises the following steps: S1, measuring the radiation dose rate of a current position ofa radiation field through a dose rate instrument, and transmitting the measured radiation dose rate data to a computer for processing; s2, measuring the spatial coordinate position of the radiation field where the dose rate instrument is located by using a total station, and transmitting the measured spatial coordinate position information to a computer for processing; s3, enabling the computer to process the dose rate data and the spatial coordinate position information received in the steps S1 and S2 to obtain the radiation dose rate and the spatial coordinate position data information of the position of the radiation field; s4, measuring the radiation dose rate of the other position of the radiation field by the dose rate instrument, and repeating the steps S1 to S3 until the radiationdose rate and the spatial position data information of the measurement point of the whole radiation field are acquired. According to the measurement method in the scheme, the workload and the workingtime can be greatly reduced, and personnel are prevented from being irradiated by excessive dose.

Description

technical field [0001] The invention relates to the technical field of gamma ray detection, in particular to a method and a measuring device for space gamma dose rate radiation field measurement. Background technique [0002] The measurement of the radiation field in three-dimensional space provides the data basis for the optimization of radiation protection, so how to measure the dose rate data of the spatial position coordinates accurately, quickly, conveniently and with the minimum exposure dose becomes the key. The general method has many disadvantages, and there is no mature measurement system and device. Specifically, the dose rate meter is used to measure the dose rate at different positions, but it is impossible to accurately obtain the coordinates and punctuation points of the current measuring point in the entire three-dimensional space. , which brings great inconvenience to the follow-up radiation field calculation and source term inversion work, so new measuremen...
