Embodiment Construction

[0049] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 As shown, the present invention utilizes the divergence of rays propagating in the air and the attenuation law in lead materials to calculate (1) under different X-ray radiation intensities, the safety distance of general public personnel, and the protective device for public personnel is designed; (2) Under different X-ray tube voltages, the lead shielding device should be equipped when the operator is at different distances from the ray source. Specifically include the following steps:

[0050] The method of the present invention is: (1) adopting that infrared warning lights and warning lines are set at places where the public is at a safe distance; (2) adopting a lead shield protective device for radiation operators;

[0051] Among them: (1) The calculation method for the safety distance of general public personnel is:

[0052] 1) The radiation intensity of the X-ray source...

Abstract

The invention discloses a field X-ray protection method and a protection device thereof. In the invention, the personnel safety is protected by spacing an infrared warning light and a warning line from the public personnel at a safe distance and equipping the ray operator with a lead shielding cover protection device. The invention has the beneficial effects that: (1) in the invention, the safe distance for common public personnel is calculated under different X-ray radiation intensities, and protection measures are arranged outside the safe protection distance so that dose received by the public personnel is controlled within a safe range; and 2) a plastic shielding cover capable of containing lead plates with different thicknesses is designed. When the shielding cover is used, the ray operator hides behind the shielding cover and thus is effectively protected.

Description

technical field [0001] The invention relates to an X-ray protection method and the resulting protection device, in particular to an X-ray protection method and device at a work site. technical background [0002] X-ray technology is playing an increasingly important role in everyday life and scientific research. In recent years, X-ray-based detection and imaging technology has been more and more applied in the fields of industry, medical treatment, and chemical industry. However, X-rays are high in energy and cause ionizing radiation when passing through the air. When any ionizing radiation irradiates an object, the irradiated object will absorb all or part of the energy of the ionizing radiation. If the irradiated object is a biological body, it will cause a biological effect, and the size of the biological effect is closely related to the amount of absorbed energy, that is to say, the more energy absorbed, the stronger the biological effect. For the human body, receivin...
