Study Notes
Measurement of Ionizing Radiation
- The unit used to measure the amount of ionizing radiation released by a material is the Gray (Gy).
Exposure
- Exposure describes the radiation energy that ionizes air and is a measure of the amount of radiation present in a specific environment.
Units of Measure for Exposure
- Common units for measuring exposure include Roentgen (R), which quantifies the ionization produced in air.
Measurement of Radioactivity
- The unit used to measure radioactivity, specifically the decay of atoms in a material over time, is the Becquerel (Bq), where one Bq equals one decay per second.
Absorbed Dose
- Absorbed dose describes the amount of energy deposited by radiation per unit mass of tissue, typically measured in Gray (Gy), where one Gy corresponds to one joule of energy absorbed by one kilogram of matter.
