Problems solved by technology

However, the measurement results of the radiation intensity value are greatly affected by changes in the external weather. In the above method of burying the cup, the process of burying the cup in each test is more than 4 hours, the time span is large, and it is seriously affected by the weather. The poor consistency of the test environment led to inaccurate detection results of radioactive geophysical surveys in the area
[0005] In addition, in the above-mentioned buried cup method, the buried cup process in each test takes more than 4 hours, and the work efficiency is low
[0006] In addition, in the above-mentioned buried cup method, the situation that the cup is easily lost

Abstract

The invention discloses a ray meter, which comprises a shell, a probe, a mainboard and a battery holder. A dark box for containing a soil sample is fixed in the shell and comprises an non-transparent casing and a drawer arranged in the casing; the probe is fixed in the shell and comprises a crystal holder and a photomultiplier, the bottom of the crystal holder is communicated with the inside of the dark box, the periphery of the crystal holder is wrapped by the casing, and the photomultiplier is fixedly connected with the crystal holder; the mainboard is fixed in the shell and is connected with the photomultiplier to convert electric signals generated by the photomultiplier, so that radiation intensity of the soil sample is obtained; and the battery holder is connected with the mainboard and fixed in the shell. The ray meter can obtain a testing result in real time, and eliminates adverse effects of weather change to detection results of radioactive geophysical prospecting.

Description

technical field [0001] The invention relates to the technical field of radioactive geophysical exploration, and more specifically, to a radiation measuring instrument. Background technique [0002] Radioactive geophysical prospecting, also known as "radioactive measurement", is the abbreviation of radioactive geophysical prospecting. It is based on the physical properties of radioactive rays, using special instruments, such as radiometers, emanators, etc., to measure the ray intensity or emanation of radioactive elements. At the same time, it is also an auxiliary means to find rare element, rare earth element and polymetallic element deposits that coexist with radioactive elements. [0003] The existing method of radioactive geophysical prospecting is the method of buried cup, that is, the cup containing the test card is buried in the soil, wait for more than 4 hours to allow the radioactive elements in the soil and the radioactive elements infiltrated on the card to reach a...
