Moderate supplementation of iodine tablets can indirectly prevent radiation because the thyroid gland is saturated by iodine tablets, reducing the absorption of radioactive iodine.
The thyroid gland can absorb iodine, which is radioactive and non-radioactive, and the thyroid gland can cause thyroid cancer by absorbing too much radioactive iodine.
The iodine in iodine tablets belongs to non-radioactive iodine 127, after consuming iodine tablets, the thyroid gland absorbs iodine 127 to reach saturation, and then it can’t absorb radioactive iodine 131, which indirectly plays a preventive effect of radiation.
Life in the general population is generally not exposed to radioactive iodine 131 or other radioactive sources, not a large number of exposure to radiation sources there is no need to supplement iodine tablets, there is a need in this regard should be carried out under the guidance of a doctor, usually wear anti-radiation clothing to reduce radiation.
