Forms that dissolve easily may be absorbed and others that don't dissolve easily are often coughed up and swallowed. Plutonium that is mixed with food or water is poorly absorbed in the stomach and leaves the body in feces. The rate of plutonium removal from the body is slow, occuring over many years. If plutonium stays in your body, your chances of developing cancer increases, but it would be several years before it's effects become apparent. It is generally assumed that any amount of absorbed plutonium, no matter how small, may cause some damage.
Urine tests are available that measure the amount of plutonium in a person's body.
Though, these tests cannot measure the level at which the person was exposed. The daughter is when there is little or no radiation left. Several ways of disposing of plutonium have been researched. One option is to mix a special glass with plutonium. The glass is made of tin, zirconium and silicon that stabilizes the glass's structure.
