so what sort of health risks are involved with the ingestion of said 1,2-iodopropane ?
It is a known mutagen/carcinogen. Look up the MSDS for 1,2-diiodopropane, which is its proper name.
and is isopropyl iodide a synonym for 1,2-iodopropane ?
No, Isopropyl iodide is 2-iodopropane.
and can 1,2-iodopropane be 'boiled off' from the end product ?
No, it will very likely react with the end product before it has a chance to evaporate. Iodoalkanes, and especially diiodoalkanes are extremely reactive at elevated temperatures.
