does iodine prevent liver damage if you are exposed to radiation?

No: Potassium iodide (ki) tablets only protect the thyroid against the harmful effects of radioactive iodine isotopes that may be in the environment after a nuclear bomb or accident at a nuclear reactor. It does not protect against other sources of radiation, and does not protect other organs from exposure to radioactive fallout.

Iodine is suppose to: Protect the thyroid gland from taking up radioactive iodine. However it takes time to build up this reservoirs. Also potassium iodide protects or affects the entire body systems not just the liver (as does ionizing radiation.)
