A radiation detection device

Abstract

The invention discloses a radiation detection device, comprising a base, on which a water tank is installed, on the base, a side support that can rotate around the water tank is installed, a cantilever is connected to the top of the side support, and a first suspender is installed on the cantilever , the second suspension rod, the water tank is provided with a horizontal support arm that can slide up and down along the second suspension rod, the horizontal support arm is provided with a fixed sleeve, the first suspension rod passes through the fixed sleeve and the two are connected by threads, The first pulley and the second pulley are installed on the horizontal support arm, the first pulley is set on the second suspender in a slidable and non-rotatable manner, and a timing belt is arranged between the first pulley and the second pulley , the timing belt is fixedly connected with a movable seat, and a nuclear radiation detector is installed on the movable seat. The invention can detect the radiation intensity at different positions of the ray path and different radii of the radiation range, the water level in the water tank can be automatically adjusted, and there is no need to temporarily add water to the water tank during use.

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
