Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0023] First, to facilitate understanding of the embodiments of the present invention, some of the terms or nouns involved in the present invention are briefly described below.

[0024] Explanation:

[0025] Radiation refers to the phenomenon that a part of the electromagnetic energy emitted by the emission source (electromagnetic waves, etc.) escapes from the source and propagates to a distant place, and then never returns to the source. The energy diffuses outward in the form of electromagnetic waves or particles (such as alpha particles, beta particles, etc.).

[0026] Radioactivity refers to the phenomenon that an element spontaneously emits radiation (such as α-rays, β-rays, γ-rays, etc.) from an unstable nucleus and decays to form a stable element and stops radiating (decay products). The energy released during decay is called decay energy.

[0027] Radiation protection is an important branch of atomic energy science and technology. It is a comprehensive frontier subject that studies how to protect humans from or reduce the harm of ionizing radiation. Its basic tasks are to protect the health and safety of people working with radioactivity, the public and their offspring, and to protect the environment.

[0028] According to an embodiment of the present invention, a method embodiment of risk assessment based on radiation hazards is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] Figure 1 is a flow chart of a risk assessment method based on radiation hazards according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0030] Step S102, obtaining basic data of radiation sources in the radiation environment;

[0031] In an optional embodiment, basic data of a radiation source in a radiation environment is obtained, including: obtaining the operating conditions of a device corresponding to the radiation source, and the material usage of the material corresponding to the radiation source; quantifying the operating conditions based on standard quantification principles to obtain operating data, wherein the standard quantification principles are used to quantify the operating conditions into digital data; quantifying the material usage based on standard quantification principles to obtain material usage data; and preprocessing the operating data and material usage data to obtain basic data.

[0032] Optionally, select the working environment (sample) of nuclear facility radiation hazard operations to conduct radiation health surveys. Through data collation and on-site investigation, conduct occupational health surveys on the workplace, including basic information of the unit, equipment operation, overall building layout, production process, production equipment and layout, basic information of workers, raw materials and usage, identification of radiation hazard factors, radiation occupational disease protection facilities, protective supplies, auxiliary rooms, emergency rescue, radiation health management, radiation occupational disease hazard factors and their temporal and spatial distribution and implementation of protection facilities, etc.

[0033] Optionally, there are many radiation sources corresponding to nuclear facilities. Common radiation sources include equipment that generates gamma rays, or CT equipment, equipment that generates dust, equipment that generates chemical agents, etc. The operation of the above equipment affects the intensity of the radiation source, that is, the younger the equipment is and the better the equipment is in operation, the more stable the radiation source is. Based on the standard quantification principle, the above content is converted into corresponding level of operation data according to the equipment operation status and equipment operation age. Among them, the operation data corresponds to the level of equipment operation status, which can be determined according to the status standard table in the relevant industry.

[0034] Optionally, the radiation source exists not only on the production equipment, but also on the products produced by the production equipment or the raw materials required to produce the products. The amount of materials used in the raw materials and the type of materials used determine the intensity of the radiation source. Based on the standard quantification principle, the above content is converted into corresponding level of material data according to the amount of materials used in the raw materials and the type of materials used. Among them, the material data corresponds to the level of material hazard, which can be determined according to the status standard table in the relevant industry.

[0035] Step S104, obtaining a protection factor corresponding to the radiation environment, wherein the protection factor is used to indicate a level factor of a protection facility in the radiation environment;

[0036] Optionally, only the intensity of radiation can be determined based on the radiation source. However, in every work involving radiation, there are protective operations. Not all radiation generated by the radiation source affects the working environment. If the protective work is comprehensive enough, the amount of radiation exposed in the radiation work can be ignored. If the protective intensity is not in place, the amount of radiation in the radiation environment will affect the safety of the protective personnel. Therefore, it is necessary to comprehensively consider the relationship between the intensity of the radiation source and the radiation coefficient to determine the actual radiation level in the working environment, thereby determining the radiation risk status of the staff.

[0037] In an optional embodiment, obtaining a protection factor corresponding to a radiation environment includes: obtaining the material and thickness of a shielding protection wall in the radiation environment; quantifying the material of the shielding protection wall based on standard quantification principles to obtain material data; and determining the protection factor based on the material coefficient and the thickness of the shielding protection wall.

[0038] Optionally, radiation protection generally takes the form of isolating radiation, that is, isolating the radiation source in a relatively closed space, or protecting the staff, using protective clothing or protective masks, etc. to isolate the radiation hazards. However, the protection level is based on the material and thickness of the protective equipment (the material of the shielding protection wall and the thickness of the shielding protection wall). The protective material can be converted into material data according to the status standard table in the relevant industry, that is, converted into the grade coefficient of material protection. A weighted calculation is performed based on the grade coefficient and the protection thickness to obtain the protection factor. The higher the protection factor, the better the protection level and the lower the radiation risk.

[0039] Step S106, determining the radiation amount based on the basic data;

[0040] In an optional embodiment, determining the radiation amount based on basic data includes: classifying the basic data to obtain radioactive data and non-radioactive data; determining the radioactive elements based on the radioactive data; obtaining the radioactive element activity, radiation energy, radiation time and attenuation distance corresponding to the radioactive elements; and determining the radiation amount based on the radioactive element activity, radiation energy, radiation time and attenuation distance.

[0041] Optionally, common radiation sources include gamma rays, CT equipment, dust and chemicals, among which gamma rays and CT equipment are both radioactive radiation, and dust and chemicals are both non-radioactive radiation. Based on the above distinction, the basic data obtained is divided into radioactive data and non-radioactive data, and the radioactive data is analyzed.

[0042] Optionally, radioactive radiation is the radiation produced by radioactive elements, which produces irreversible radiation damage to equipment in the working environment, thereby causing irreversible radiation damage to personnel in the working environment. The degree of damage is higher than that caused by non-radioactive elements, and the speed of producing radiation damage is faster. In the absence of protection, the radiation produced by radioactive elements can directly cause lesions in workers. Based on the radioactive data, the radioactive elements produced in the equipment corresponding to the radiation source are determined, so as to obtain the radioactive element activity, radiation energy, radiation time and attenuation distance corresponding to the radioactive element; based on the radioactive element activity, radiation energy, radiation time and attenuation distance, the radiation amount is determined.

[0043] Optionally, the specific amount of radioactive element radiation is:

[0044] Radiation amount = activity of radioactive element × radiation energy × time × attenuation coefficient / (4π × distance ∧2)

[0045] Among them, the activity of the radioactive element is the number of particles or photons emitted by the radioactive element per unit time, and the unit is becquerel (Bq); the radiation energy is the radiation energy emitted by the radioactive element, and the unit is joule (J) or electron volt (eV); time is the time of radiation measurement, and the unit is second (s); the attenuation coefficient is the absorption capacity of the medium to radiation, which is a constant related to the characteristics of the medium; 4 is the unit spherical area; the distance is the distance from the radiation source to the receiving point, and the unit is meter (m).

[0046] Step S108, determining the radiation exposure of the sample based on the radiation dose and the protection factor, wherein the radiation exposure of the sample is used to indicate the degree to which the sample is exposed to radiation under the influence of the radiation dose and the protection factor;

[0047] In an optional embodiment, the radiation exposure of the sample is determined based on the radiation dose and the protection factor, including: determining the unit exposure based on the radiation dose and the protection factor, wherein the unit exposure is used to indicate the radiation exposure of the sample in a unit time period; obtaining the exposure time of the sample; and determining the radiation exposure based on the unit exposure and the exposure time.

[0048] Optionally, under the same radiation dose, the longer the exposure time in the radiation environment, the higher the radiation level. Unit exposure = radiation dose - protection factor × attenuation coefficient. Among them, the attenuation coefficient is the absorption capacity of the medium to radiation, which is a constant related to the characteristics of the medium. When the unit exposure is determined, the radiation exposure is determined by multiplying the unit exposure by the exposure time.

[0049] Step S110, determining a radiation risk assessment result based on the radiation exposure.

[0050] In an optional embodiment, before determining the radiation amount based on the basic data, the method also includes: classifying the basic data to obtain radioactive data and non-radioactive data; determining a first risk level and a risk possibility corresponding to the non-radioactive data, wherein the risk possibility is used to indicate the possibility of the occurrence of the first risk level; determining a non-radioactive risk assessment matrix diagram based on the first risk level and the risk possibility; and determining a second risk level based on the non-radioactive risk assessment matrix diagram.

[0051] Optionally, the basic data contains not only radioactive data but also non-radioactive data. Specifically, non-radioactive factors may also cause certain harm to the workers (samples), so it is necessary to comprehensively consider the influence of radioactive factors and non-radioactive factors to determine the radiation risk assessment.

[0052] Optionally, based on the non-radioactive data, a first risk level of the non-radioactive data is determined, wherein the first risk level is determined based on the "Industrial Enterprise Design Hygiene Standard (GBZ1)" and the "Workplace Hazardous Factor Exposure Limit (GBZ2)". Based on the non-radioactive substances indicated in the non-radioactive data, a machine learning algorithm is used to calculate the possibility of the first risk level existing.

[0053] Optionally, based on the first risk level and risk likelihood generated by the non-radioactive data, a non-radioactive risk assessment matrix diagram is constructed, such as Figure 2 As shown, Figure 2It is a non-radioactive risk assessment matrix diagram of a risk assessment method based on radiation hazards according to an embodiment of the present invention, wherein the horizontal axis of the non-radioactive risk assessment matrix diagram is the first risk level, and the vertical axis is the second risk level. Based on the non-radioactive risk assessment matrix diagram, when the horizontal axis and the vertical axis are determined, the second risk level is obtained, that is, the radiation risk level caused by non-radioactive factors.

[0054] In an optional embodiment, a radiation risk assessment result is determined based on the radiation exposure, including: determining a third risk level corresponding to the sample based on the radiation exposure, wherein the third risk level is used to indicate the risk level of the sample after being irradiated by radioactive elements; weighting the second risk level and the third risk level to obtain a fourth risk level; and determining the radiation risk assessment result based on the fourth risk level.

[0055] Optionally, there are two types of radiation: non-radioactive and radioactive. The non-radioactive risk level is determined based on the non-radioactive risk assessment matrix, and the radioactive risk level is determined based on the International Commission on Radiological Protection; the International Commission on Radiological Protection (ICRP) and the International Atomic Energy Agency (IAEA), the Nuclear and Radiation Accident Scale and the Radiation Safety Management Manual for Nuclear Facility Operation, which classify the radiation exposure of workers. The classification levels are divided into 3, 5, 7 or more according to the radiation hazard levels of different nuclear facilities, resulting in a third risk level.

[0056] Optionally, the fourth risk level calculation is as follows:

[0057] Fourth risk level = second risk level × S1 + second risk level × S2

[0058] Among them, S1 is the non-radioactive radiation coefficient, which is used to indicate the proportion of non-radioactive radiation impact, and S2 is the radioactive radiation coefficient, which is used to indicate the proportion of radioactive radiation impact.

[0059] Through the above steps S102 to S110, the purpose of comprehensively considering the relationship between the radiation amount brought by the radiation source and the protection factor can be achieved, thereby achieving a technical effect of more comprehensive consideration of factors and more accurate radiation risk assessment results, thereby solving the technical problem.
