Are x rays emitted during radioactive decay

Electromagnetic ionizing radiation emitted from the nucleus of an atom when it de-excites. Gamma rays are best thought of as "photons," i.e., packets of pure energy. The energy of a gamma ray is usually between 50 and 2000 keV (0.05 to 2 MeV). Gamma rays can be emitted during radioactive decay.

Pretty sure the answer is b : )

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
