GLOSSARY OF NUCLEAR TERMS
REFERRED TO IN CASE DIGESTS
. Alpha radiation~A stream of positively charged alpha particles emitted
by certain radioactive materials. It is the least penetrating of the three
common types of radiation (alpha, beta, gamma). Alpha particles cannot
penetrate the outer layers of human skin but if an element releasing
them is deposited within the body, they may cause damage by
destroying focal tissue,
. Beta radiation- A stream of negatively or positively charged particles
emitted from the nucleus of certain radioactive materials.
. Curie—(Symbols commonly used are C, c, and Ci)—The basic unit to
describe the intensity of radioactivity in a sample of material. The curie
is equal to 37 billion disintegrations per second, which is approximately
the radioactivity of ! gram of radium. A curie is also a quantity of any
nuclide having {| curie of radioactivity.
. Dose—The amount of ionizing radiation energy absorbed per unit mass
of irradiated material at a specific location, such as a part of the human
body.
. Dosimeter—A device that measures radiation dose, such as a film badge.
. Fallout--Debris (radioactive material} that resettles to earth after a
nuclear explosion.
. Film badge—A package of photographic film worn like a badge by
workers in the nuclear industry to measure exposure to ionizing
radiation. The absorbed dose can be calculated by the degree of film
darkening caused by the irradiation.
. Fission Products—The nuclei formed by the fission of heavy elements,
plus the nuclides formed by the fission fragments’ radioactive decay.
. Gamma_Radiation—High-energy, short wavelength electromagnetic
radiation emitted from the nuclei of many radioactive materials. Gamma
radiation is very penetrating and is best shielded against by dense |
materials, such as concrete or lead.
