At present, there are three main ways to prevent radiation:
1, metal shielding, that is, shielding the radiation of the main body with metal-containing substances, and electromagnetic radiation will be reflected to other places, such as radiation-proof maternity clothes on the market at present.
2. Absorbing materials, such as ferrite, can convert radiation into heat energy and dissipate it.
3, through the improvement of autoimmune ability, such as foods rich in vitamins and protein.
Therefore, jasper flower has no practical significance in radiation protection.
