Problems solved by technology

[0003] Although there is a consensus that electromagnetic radiation can cause damage to organisms, its mechanism of action has not been fully clarified.
On the one hand, because the energy of electromagnetic radiation is low, and the effect of electromagnetic radiation on living organisms is fluctuant and reversible (compared with ionizing radiation), the current use of commonly used electromagnetic radiation experiments such as cells, small animals, and large animals , there is still no exact sensitive index (or response index) that can be used in the research model of electromagnetic radiation damage effect to evaluate the damage degree of electromagnetic radiation quantitatively and / or qualitatively
On the other hand, there are large differences in the research objects, radiation doses, irradiation methods, and irradiation times of different research models, and the results obtained cannot be systematically studied and compared quantitatively, and even the results obtained are contradictory.
In addition, because the relationship between the dose-effect and time-effect of electromagnetic radiation hazards is not yet clear, there is no unified standard for the evaluation of electromagnetic radiation damage, which is also one of the reasons why it is impossible to conduct qualitative or quantitative evaluation of electromagnetic radiation damage.

Embodiment 1

[0034] This embodiment uses the method of the present invention to evaluate the electromagnetic radiation damage degree of a microwave radiation device, as an example. The natural frequency of the microwave rays emitted by the microwave radiation device is 9.375GHz, the peak power is 897.97W, and the pulse width is 100ns.

[0035] In this example, a set of evaluation system dedicated to the method of the present invention was used. The structure of the evaluation system is as follows figure 1 As shown, including a radiation source 1 (purchased from Wuhu Guorui Megavolt Electronics Co., Ltd.) and a petri dish 4, the radiation source 1 is connected to the horn antenna 3 through a waveguide 2, and the waveguide 2 is used to transmit the microwave signal of the radiation source 1 to horn antenna 3. The horn antenna 3 is placed at 15-25 cm (preferably 20 cm) directly above the culture dish 4 to release microwave signals. The culture dish 4 contains culture medium and Caenorhabdi...

Embodiment 2

[0044] In this embodiment, the method of the present invention is used to evaluate the biological effects of electromagnetic radiation. The specific process is the same as in Embodiment 1, except that rays of different natural frequencies are used for irradiation, and a series of linear equations corresponding to the rays of each natural frequency are obtained. From these equations, it can be compared that:

[0045] When the intensity of electromagnetic radiation is the same, the numerical value of the electromagnetic damage index N corresponding to the rays of different natural frequencies, the larger the value of N, the more serious the electromagnetic damage of the rays of the natural frequency to the living beings, and the smaller the value of the natural frequency The less the degree of electromagnetic damage to living things, the more rays.

[0046] Even if the intensity of electromagnetic radiation is different, the electromagnetic damage degree of rays of different nat...

Abstract

The invention discloses a quantitative evaluation method and evaluation system for electromagnetic radiation damage and electromagnetic radiation biological effect. According to the quantitative evaluation method, a linear relation between the escape number of caenorhabditis elegans and electromagnetic radiation intensity is constructed, so that the damage degree of electromagnetic radiation to organisms is evaluated. Response indexes used in the evaluation method are non-invasive, the influence of the response indexes on experimental objects is small, the established dose-effect relationship is stable, and the damage degree of the electromagnetic radiation to the organisms can be stably and reliably evaluated. The evaluation method is simple in operation, stable in model, not easy to be interfered by external factors, and suitable for being applied to electromagnetic radiation damage evaluation and electromagnetic radiation biological effect evaluation. The evaluation system used in the evaluation method is simple in structure, high in operability and wide in application range.

technical field [0001] The invention relates to the technical field of electromagnetic radiation biological effects and biological safety evaluation, in particular to a quantitative evaluation method for electromagnetic radiation damage established based on the principle of Caenorhabditis elegans evasion behavior, a quantitative evaluation method and an evaluation system for electromagnetic radiation biological effects. Background technique [0002] In recent years, with the extensive use of electrical equipment and the rapid development of wireless communication technology, electromagnetic radiation pollution has become the fourth largest pollution after air pollution, water pollution and noise pollution. Electromagnetic radiation can not only cause serious damage to electronic systems, but also cause damage to organisms, especially the degree of damage to human health has reached a level that cannot be ignored. [0003] Although there is a consensus that electromagnetic ra...
