Across:

3.	the particles that are released from the nucleus during radioactive decay, such as neutrons, electrons, and photons
6.	the process in which light nuclei combine at extremely high temperatures, forming heavier nuclei and releasing energy
7.	the high-energy photon emitted by a nucleus during fission and radioactive decay

8.	the time required for half of a sample of a radioactive isotope to break down by radioactive decay to form a daughter isotope
9.	the disintegration of an unstable atomic nucleus into one or more different nuclides, accompanied by the emission of radiation, the nuclear capture or ejection of electrons, or fission
10.	an electron or positron that is emitted from a nucleus during radioactive decay

Down:

1.	a radioactive material that is added to a substance so that its distribution can be detected later
2.	the nuclear radiation that arises naturally from cosmic rays and from radioactive isotopes in the soil and air
4.	a positively charged atom that is released in the disintegration of radioactive elements and that consists of two protons and two neutrons

5.	a continuous series of nuclear fission reactions
6.	the process by which a nucleus splits into two or more fragments and releases neutrons and energy
