You are working in an astrophysics lab studying newly discovered asteroids. You determine that one of the asteroids is emitting radiation but you are not sure what kind. You use a spectroscope and determine that the asteroid has large deposits of two very heavy, dense elements with one element being slightly lighter than the other. You determine that the heavier element is decaying into the lighter element. What type of radiation is it most likely emitting? A. Gamma B. Delta C. Beta D. Alpha
