Chapter 4 Key Terms
Across
- 6. Mutational or randomly occurring biologic changes in which the changes of occurence of the effect rather that the severity of the effect is proportional to the dose of ionizing radiation
- 7. Designated for use in the description of a population or group exposed to different individual amounts of ionizing radiation
- 11. A system of units and quantities used to monitor occupationally exposed personnel such as nuclear medicine technologists and interventional radiologists
- 14. nongenetic consequences of radiation exposure that appear months or years afterward
- 17. The total electric charge of one sign per unit mass that x-ray and gamma ray photons with energies up to 3 million electron volts generate in dry air at standard temperature and pressure
- 18. The mean quantity of energy deposited by ionizing radiation in an object per unit length of track as it passes through the object

- 20. Measurement of the probabilistic health effect on an individual as a result of intake of radioactive material into the body
- 21. Biologic effects in humans caused by exposure to ionizing radiation
- 22. Common units that makes possible a standard system of units among all branches of science throughout the world
Down
- 1. SI unit of radiation exposure
- 2. The amount of energy per unit mass absorbed by an irradiated object
- 3. A radiation quantity used for radiation protection purposes when a person receives exposure from various types of ionizing radiation
- 4. Quantity that is used for radiation protection purposes to provide a measure of the overall risk of exposure to humans from ionizing radiation
- 5. The sum total of air kerma over the exposed area of the patient's surface
- 8. Biologic effects of ionizing radiation on future generations due to irradiation of germ cells in previous generations
- 9. SI unit of absorbed dose and air kerma
- 10. A dimensionless factor that was chosen for radiation protection purposes to account for differences in biologic impact among various types of ionizing radiations
- 12. Represents the quantity of electrical charge flowing past a point in a circuit in 1 second when an electrical current of 1 ampere is used
- 13. A value that denotes the percentage of the summed stochastic risk stemming from irradiation of specific tissues to the all-inclusive risk when the entire body is irradiated in a uniform fashion
- 15. SI quantity that can be used to express radiation energy transferred to a point, such as the surface of a patient's or radiographer's body
- 16. The SI unit of measure for the radiation quantities, equivalent dose and effective dose
