Description

technical field [0001] The invention belongs to the technical field of radiation protection in environmental protection, and in particular relates to an environmental protection device for eliminating radiation hazards of nuclear magnetic resonance to human bodies. Background technique [0002] NMR is a physical process in which the magnetic moment of an atomic nucleus whose magnetic moment is not zero undergoes Zeeman splitting at the spin level under the action of an external magnetic field, and resonantly absorbs radio frequency radiation of a certain frequency. The basic principle is to place the object under test in a special magnetic field, and use radio frequency pulses to excite the atomic nuclei in the object under test, causing the nucleus to resonate and absorb energy. After the radio frequency pulse is stopped, the nucleus emits a radio signal at a specific frequency, and releases the absorbed energy, which is recorded by a receiver outside the object to be teste...

AI Technical Summary

Problems solved by technology

[0006] Because radio frequency pulses are needed to excite the atomic nuclei in the object to be tested, this leads to easy radiation. If users stay in such an environment for a long time, their health will often be damaged, which is not conducive to the promotion and use of nuclear magnetic resonance technology.

However, in the process of using nuclear magnetic resonance, the devices in the prior art have a plurality of hole structures, resulting in ineffective elimination of radiation, causing radiation hazards to the human body.
