- Absorbed dose :
-
A general term for the energy transferred from radiation to matter. Specifically, the absorbed dose is the amount of energy absorbed in a unit mass of matter from ionizing radiation. Units are the gray (Gy) and rad, respectively, equivalent to 1 J/kg and 100 ergs/g. Thus, 1 Gy equals 100 rad.
- Activity :
-
The decay rate (expected number of nuclear transformations per unit time) in a radioactive sample. Units are the becquerel (Bq) equal to one decay per second, and the curie (Ci) equal to 3.7 × 1010 decays per second.
- Alpha particle :
-
The nucleus of a 4He atom, composed of two neutrons and two protons and denoted by α.
- Committed dose :
-
The dose equivalent accumulated over the rest of a person’s life following the ingestion or inhalation of radioactive material into the body.
- Coulomb force :
-
The electrostatic force between two charges. It is proportional to the product of the charges and inversely proportional to the square of the distance between them. The force is...
