@Evaldas521 The only reason you would drink an iodine based compound is because during a nuclear bomb explosion, radioactive iodine is produced which can be inhaled and ingested. Iodine compounds are concentrated in the thyroid gland. If you ingest isotopic iodine, you get thyroid and other related cancers. Taking non-isotopic iodine compounds saturates the thyroid so that it can no longer take any iodine even if it is in its isotopic form

You can still die from general radiation exposure though

No, but iodine does stain quite a bit. That's why you've gotta where gloves and an apron, if it gets on your clothes or even your skin, well, it's not coming off.

thats iodate, im not sure if thats the same

[chemoxid]

nice video...

but what it is "potassium metaperiodate"?? wouldnt be ..potassium chlorate??

[Sectorsophia]

Very cool. Thanks!

If you get radiation poisoning you drink potassium iodide. Elemental iodine is a halogen and inhaling a gaseous halogen is always bad. That's like saying that inhaling chlorine gas is a good idea because table salt is nontoxic.

[Evaldas521]

I don't think it is, cos if you get radiation you're supposed to DRINK iodine...

[Darkdayzz]

If that we're true this experiment would be done in (forgot the english word so) a thing which would filter out everything now wouldnt it?

[Wuzzi55]

isn't iodine toxic?

Heb je al deze spullen van Woelen gekregen?

Kaliummetaperjodaat weet ik niet zo 1 2 3 in de supermarkt te vinden.
