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 thyroid gland is the part of the body that is most sensitive to radioactive iodine.
The pier will soon become the Gulf of Mexico's longest, surpassing the 1,540-foot pier opened in July at Gulf State Park.
The town of Progreso, Mexico, sits on a limestone shelf that falls away extremely gradually as it gets further out to sea. As a result, when they built a pier to allow cruise ships to dock here, it had to be long. Really long. Measuring a phenomenal 6.5 kilometers (4 miles), this is the worldâs longest pier. The original pier was completed in 1942, and despite being little more than a two-lane highway, is actually quite nice looking seen from the beach.
