Radioactivity is caused when an atom, for whatever reason, wants to give away some of its energy. It does this because it wants to shift from an unstable configuration to a more stable configuration. The energy that is released when the atom makes this shift is known as radioactivity. In ...
protons, neutrons and electrons. The protons and neutrons are in the nucleus of an atom. The smallest particles, the electrons, circle around the nucleus. If the atoms in objects lose any of these small particles, high-energy waves are produced, and this is what makes an object radioactive...
A radioactive atom has a higher energy than it needs to have. Energy in the universe tends to spread out, and so when something has more energy than it needs, it's only a matter of time until it loses that energy. When a radioactive atom loses its extra energy by decaying, that ...
What part of an atom undergoes change during radioactive decay? In what form does all radiant energy travel through space? What is the relationship between electrical energy and nuclear energy? What is the energy of a photon of green light?
aThe probe has previously been labeled, typically with radioactive atom, fluorescent dye or tagged with an enzyme that generates a chemiluminescent signal when incubated with an appropriate substrate. After hybridization, the labeled probe allows the DNA fragment of interest to be detected from among ...
Radioactive Contamination Since the radioactive substance is in direct contact with the inside or outside of the body, this form of infiltration increases the danger by two-fold. Not only does it expose the body to the effects of radiation poisoning, but also causes internal damage by affecting...

Isotopes are forms of an element with varying numbers of neutrons in the nucleus of the atom. As radioisotopes decay, they slowly transform into other isotopes of the same element through gaining or losing neutrons, and eventually they become other elements entirely. This depends on their decay ...
Yes, to a degree the human body, and all lifeforms, are radioactive. Every day, at least one atom in your body splits apart. But don't worry. You have hundreds of billions of atoms to go (if not more). It will take a very long time for your body to be reduced to sub-atomic...
