Zhao Fuqun that, because the fluorescent rods in the liquid chemical substances are polyethylene (plastic) packaging, it will not cause too much harm to the human body. Because the light emitted by the light bar is a non-radioactive light emitted by the chemical reaction-excited dye, rather than the light emitted by the radiation-stimulating dye, it does not harm the human body.
