Isotopes utilized in nuclear medicine fall into two broad categories: Stable and Unstable. Stable isotopes do not undergo radioactive decay. WHAT IS A STABLE ISOTOPE? A stable isotope is any of two or more forms of an element whos nuclei contains the same number of protons and electrons, but a different number of neutrons. Stable isotopes remain unchanged indefinitely, but unstable (radioactive) isotopes undergo spontaneous disintegration.
Langostino is a Spanish word with different meanings in different areas. In the United States, it is commonly used in the restaurant trade to refer to the meat of the squat lobster, which is neither a true lobster nor a prawn. Squat lobsters are more closely related to porcelain and hermit crabs. Crustaceans labeled as langostino are no more than 8 cm (3 in) long, and weigh no more than 200 g (7 oz). Langostinos are not langoustes (spiny lobsters) despite a similar name (in Spanish, lobster is called langosta).
