And in the aftermath of the March 2011 earthquake and tsunami that struck Japan, a nuclear crisis raised fears about radiation and questions about the safety of nuclear power.­Nuclear radiation can be both extremely beneficial and extremely dangerous. X-ray machines, some types of sterilization equipment and nuclear power plants all use nuclear radiation -- but so do nuclear weapons.This smaller nucleus is easier to keep in a stable form. In negative beta decay, the nucleus contains an excess of neutrons.To correct this unstable condition, a neutron is converted into a proton, which keeps the nucleus the same size (i.e., the same atomic mass) but increases the number of protons (and therefore the atomic number) by one.This assumption is backed by numerous scientific studies and is relatively sound.
