Radioactive ray detection device

Abstract

The invention discloses a radioactive ray detection device which comprises a base, a water containing tank is mounted on the base, a side support is mounted on the base and capable of rotating around the water containing tank, a cantilever connected to the top end of the side support, a first suspender and a second suspender rotatably mounted on the cantilever, and a horizontal supporting arm is arranged in the water containing tank and capable of sliding up and down along the second suspender. A fixed sleeve is arranged on the horizontal supporting arm, the first suspender penetrates through the fixed sleeve and is in threaded connection with the fixed sleeve, a first belt wheel and a second belt wheel are installed on the horizontal supporting arm, the first belt wheel is sleeved on the second suspender in a slidable and non-rotatable mode, a synchronous belt is arranged between the first belt wheel and the second belt wheel, and a movable seat is fixedly connected to the synchronous belt; and a nuclear radiation detector is mounted on the movable seat. The radiation intensity of different positions of a ray path and different radiuses in a radiation range can be detected, the water level in the water containing tank can be automatically adjusted, and water does not need to be temporarily added into the water containing tank in the using process.

Description

technical field [0001] The invention relates to the technical field of radiation measurement, in particular to a radiation detection device. Background technique [0002] With the development of science and technology, nuclear radiation technology is widely used in different fields such as medical treatment, security inspection, industrial and agricultural production. For example, X-rays are used in radiation therapy and safety inspection, X-rays are used in industrial flaw detection, and gamma rays are used in agricultural breeding. In order to ensure the safety and effectiveness of radiation use, it is necessary to detect the radiation intensity of radiation in advance, which requires the use of radiation detection devices. [0003] The existing radiation detection device includes a water tank, in which a nuclear radiation detector is fixedly installed, and water is filled in the water tank, and the nuclear radiation detector is submerged underwater to a certain depth, so...

Problems solved by technology

[0004] The disadvantage of this radiation detection device is that the nuclear radiation detector is fixedly installed in the water tank. When it is necessary to detect the radiation intensity at different positions of the ray path and different radii of the radiation range, it is necessary to frequently adjust the height and horizontal position of the water tank. Very inconvenient to adjust due to the heavy tank
