Since the horrible Earthquake and Tsunami hit Japan, there have been people talking about Potassium iodide that can probably help in neutralizing the effects of the radioactive particles that are supposedly flying all over the world.

But the question is that is PI really an effective combat if there are any radioactive emissions waiting to grab you and how much of it is enough? What are the exceptions of it, who will be harmed by it more than benefitted?

All the common man is aware of is that the radioactive elements are to attack the thyroid gland and there is something known as potassium iodide that can help in prevention of the same. It is an essential hormone that controls many functions of the body.

It controls the temperature and the energy rates of the body. The fact to be understood is that it is not going to act as a life saver even if you take it in excessive quantities. It just might be able to nurse the injured glands. This is a myth due to which people might start getting infected by other diseases.
