Ray irradiating rig and safety detection equipment

Abstract

The invention discloses a ray irradiation rig and safety detection equipment. The ray irradiating rid comprises a ray source, a shielding shell, a grating ruler and a control unit; the ray source is used for providing rays; the shielding shell is used for accommodating a cavity for the ray source and an opening communicated with the cavity to enable the ray to be irradiated outwards through the opening; the grating ruler is used for acquiring position information of the ray source; the control unit is used for controlling the ray source to move from a first position or a second position; the first position is where the ray is irradiated outwards through the opening; the second position is where the ray cannot be irradiated outwards through the opening. By the arrangement, the ray with high frequency can be irrigated, impact produced by irradiating of the ray on the shielding shell can be reduced, irradiating dose is reduced, and meanwhile, irradiation protection difficulty is lowered.

Description

technical field [0001] The invention relates to the application field of nuclear technology, in particular to a radiation irradiation device and safety detection equipment. Background technique [0002] At present, radiation safety detection equipment has been widely used in stations, subways, airports, customs, ports, nuclear power plants, government agencies, postal inspection centers, courts, meeting places, etc., through the radiation passing through the object to be tested, the detector set on the other side The signal is collected to obtain the attenuation intensity of the ray after penetrating different substances, so as to distinguish the density of the detected object and obtain different grayscale images, so as to perform safety inspection on the object or vehicle. [0003] A double-projection radiation imaging detection technology for large trucks and containers is known, wherein isotopes are set as radiation sources. The radiation source is usually placed in a h...

Problems solved by technology

However, due to the heavy shutter structure, the opening and closing speed of the shutter is slow, and the impact force is large, the opening time is long, and the positioning is not accurate, resulting in a large radiation dose required for detection and a large shutter size.
