Can one use iodine tablets made of tetraglycine hydroperiodide to protect yourself from radiation poisoning in an emergency? If so, how much should one take?
The CDC recommends adults take 130mg of Potassium Iodide in the event of a radioactive emergency to saturate the thyroid with iodine and prevent absorption of radioactive iodine.
KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury.
The FDA has approved two different forms of KI (potassium iodide), tablets and liquid, that people can take by mouth after a radiation emergency involving radioactive iodine.
Adults should take 130 mg (one 130 mg tablet OR two 65 mg tablets OR two mL of solution)
In this treatment, the Potassium in the salt is not relevant.
The CDC also explicitly states that the iodine present in some table salts is not sufficient to provide protection
Table salt and foods rich in iodine do not contain enough iodine to block radioactive iodine from getting into your thyroid gland. Do not use table salt or food as a substitute for KI.
However, the CDC does not mention anything about tetraglycine hydroperiodide, which is readily available as an emergency water purification tablet. These tablets are common household items for backpackers. For example, REI (a popular store for trekking in the US) sells iodine tablets with 20mg of tetraglycine hydroperiodide, 50 tablets per bottle.
Is it safe to use tetraglycine hydroperiodide to flood the thyroid with stable iodine (thereby prevent absorption of radioactive iodine into the thyroid) in a radioactive emergency? If so, what is the recommended dose of tetraglycine hydroperiodide that one should take?
