Problems solved by technology

[0004] Since the annual dose limit of the eye lens is set as 150mSv in both international and domestic standards, this limit is relatively high, so people have neglected the monitoring and protection of the eye lens before, and there is no special monitoring and protective equipment

Embodiment Construction

[0022] Such as Figure 1 to Figure 3 As shown, a mask with both radiation dose measurement and protection functions includes a protective mask 1, a rotating mechanism 3 connected to the protective mask 1 and a fixing device 4 connected to the rotating mechanism. The protective mask 1 is suitable for turning up and down through the rotating mechanism , the fixing device is used to install the protective mask 1 on the human head, safety helmet or medical lead cap;

[0023] The protective mask 1 is provided with a radiation dose measuring device 2, and the radiation dose measuring device 2 includes an outer shell 21 and an inner shell 22 which are mounted on the protective mask 1 and interlocked with each other, and are installed between the outer shell 21 and the inner shell 22. The radiation dose measuring element, the end face of the outer shell 21 is located outside the protective mask 1, the end face of the inner shell 22 is located inside the protective mask 1, and the radi...

Abstract

The invention relates to a mask with radiation dose measurement and protection functions. The mask comprises a protective mask, a rotating mechanism connected with the protective mask and a fixing device connected with the rotating mechanism, wherein the protective mask is suitable for turning over up and down through the rotating mechanism, and the fixing device is used for mounting the protective mask on the head of a human body, a safety helmet or a medical lead cap; and a radiation dose measurement device is arranged on the protective mask. A radiation dose value can be obtained by counting a measurement value of a radiation dose measurement element in the radiation dose measurement device, so that the monitoring and evaluation of the radiation dose in the personal working environmentare realized, and the personal protection is realized through the blocking and attenuation effects of the corresponding protective mask; and in addition, the protective mask is suitable for turning over up and down through the rotating mechanism, the fixing device is used for mounting the protective mask on the head of the human body, the safety helmet or the medical lead cap, the protective maskis firmly mounted and suitable for rotating up and down, the overall mounting is convenient, and the operation is flexible.

Description

technical field [0001] The invention relates to the field of ionizing radiation protection, in particular to a mask with both radiation dose measurement and protection functions. Background technique [0002] The lens of the eye (lens) is a double-convex transparent tissue, which is one of the important refractive media in the eyeball and is also an ionizing radiation-sensitive tissue. When they receive a single large dose or multiple small doses of radiation exposure, radiation damage will occur, resulting in eye lens lesions, clouding of the lens, and more severe cataracts. [0003] In the process of engaging in various practical activities related to ionizing radiation, the head and eye lens may receive higher doses of radiation due to the proximity of the head to the radiation source, the strength of the radiation field, or the lack of protection of the eyes. irradiated. For example, those involved in interventional therapy and preparation of radioactive drugs in medic...
