Method for providing stable and uniform magnetic field environment to power frequency low-intensity magnetic field biological effect experiment

Abstract

The invention belongs to the technical field of a low-frequency magnetic field radiation system in an electromagnetic biological effect research, and in particular relates to a method for providing a stable and uniform magnetic field environment to a power frequency low-intensity magnetic field biological effect experiment. The method at least comprises the following steps of: installing a magnetic field radiation system on a cell incubator, and arranging a Helmholtz coil in the magnetic field radiation system inside the cell incubator; arranging a radiation carrying support in the center shaft of the Helmholtz coil; and inputting a stable power frequency sine wave signal into the Helmholtz coil, so that a stable and uniform magnetic field is generated inside the Helmholtz coil; and placing a separation on the radiation carrying support after the magnetic field radiation system is preheated for a certain period to perform a biological effect experiment. The method provided by the invention has the advantages that operation is convenient, temperature and humidity are controllable, running can be carried out for a long term, magnetic field is stable and uniform and uniform area is large, and the intensity of the magnetic field can be checked and calculated in real time by virtue of an ampere meter, so that the requirement for the separate magnetic field biological effect can be completely fulfilled.

Description

technical field [0001] The invention belongs to the technical field of low-frequency magnetic field irradiation systems in the research of electromagnetic biological effects, and specifically relates to a method for providing a stable and uniform magnetic field environment for power frequency weak magnetic field biological effect experiments. Background technique [0002] There are power frequency magnetic fields in people's living environment, such as near high-voltage lines and around household appliances. The impact of power frequency magnetic field on human health, its biological effects and its mechanism research has become a hot spot of global concern and research by many scholars. [0003] A large number of epidemiological statistical studies have shown that magnetic field exposure will increase the incidence of cancer, among which leukemia, breast cancer and brain cancer are the majority. On the basis of summarizing previous studies, the researchers proposed that th...

However, in order to effectively control the temperature in the irradiation area, the device is equipped with a small fan, and the operation of the fan will affect the magnetic field in the irradiation area, so the field of bioelectromagnetic research is quite controversial about this device

However, there is no power frequency magnetic field irradiation system specially applied to the biological effects of in vitro magnetic fields in China.
