Power stations – radioactive isotopes of iodine - people who work at facilities using radioactive iodine may be exposed to higher than normal levels.
Iodine-131 is the radioactive gas that was released during the 1986 Chernobyl nuclear accident.
At room temperature, Iodine crystals will volatize into a violet-blue gas. In this gaseous state, Iodine is extremely poisonous and severely irritates the lungs, eyes and bronchial tubes.
|1.5 - 2 ppm||Eye, skin and throat irritation|
|3 - 5 ppm||Tearing of the eyes|
|10 - 20 ppm||Burning of nose and throat, difficulty in breathing and heavy tearing of the eyes|
|25 - 50 ppm||Chest tightening, irregular heartbeat, severe lung irritation, pulmonary edema|
|100 ppm||Immediately dangerous to life and health, death.|
Iodine is difficult to detect with real-time monitoring instruments. Evidence sampling should be done in well-ventilated areas using appropriate respiratory protection.
|Health||3||Can cause serious or permanent injury.|
|Flammability||0||Will not burn under typical fire conditions.|
|Instability||0||Normally stable, even under fire conditions|
