Frequently Asked Questions

What is a definition in chemistry of radioactivity?

Radioactivity refers to the decay or splitting of an atomic nucleus. A radioactive material releases radiation when it decays. Examples of decay include alpha decay, beta decay, gamma decay, neutron release, and spontaneous fission. All radioactive isotopes release radiation, but not all radiation comes from radioactivity.

What does radioactive mean in science?

When isotopes decay they can lose some of their atomic particles (i.e. electrons and protons) and turn from one element into another. Sometimes isotopes decay from one unstable isotope into another unstable isotope. This can happen continuously in a long radioactive chain. An example of a radioactive chain is uranium-238. As it decays, it transforms through a number of elements including thorium, radium, francium, radon, polonium, and bismuth.

How does radiation relate to chemistry?

How does radiation relate to chemistry? Radiation chemistry is the study of the chemical effects of radiation on the matter; this is very different from radiochemistry as no radioactivity needs to be present in the material which is being chemically changed by the radiation. An example is the conversion of water into hydrogen gas and hydrogen ...

What does a radioactive chemical mean?

The term "radioactive" means that certain isotopes of some chemical elements have an unstable nucleus that will spontaneously decay with the concurrent emission of ionizing radiation. The ionizing radiation, which can cause cellular damage in humans and other species, includes types called alpha, beta, and gamma radiation.
