> I'm supposed to have a barium swallow. I don't really know why. Isn't that radioactive?
Rather than being radioactive, barium is radio-opaque. It blocks x-rays. When you swallow the liquid, it coats the soft tissues of the esophagus, making them visible to the radiologist. It's used to diagnose e.g. hiatal hernia, GERD, or other conditions.
The barium sulfate liquid is often mixed with sodium bicarbonate (baking soda) to produce gas, which will stretch the esophagus to show if there is a diverticulum (a pouch, or a bulge, in the esophagus).
