Flashcards in Rad Pro Chapter 1 Vocab Deck (14):
1

Direct effect

The result of ionization and excitation, an interaction that happens directly on a critical biologic macromolecule

2

Epilation

Hair loss

3

Erythema

Reddening of the skin

4

Fractionation

The splitting of radiation into smaller amounts over a period of time

5

Indirect Effect

A cell interaction that occurs if the initial ionizing incident takes place on a distant noncritical molecule that then transfers the ionization of energy to another molecule

6

Law of Bergonie and Tribondeau

1. Stem or immature cells are more radiosensitive than mature cells.
2. Younger tissue and organs are more radiosensitive than older tissue and organs.
3. The higher the metabolic cell activity, the more radiosensitive it is
4. The greater the proliferation and growth rates for tissues, the greater the radiosensitivity.

7

Mutagenesis

The causing all genetic mutation by radiation

8

Oxygen Effect

Name given to a cellular response to radiation when oxygen is present

9

Protraction

The time during which a course of radiation is given

10

RAD

The unit of radiation absorbed dose

11

Radioactivity

The capability of a material to get off rays or particles from its nucleus

12

Radiobiology

Division of biology concerned with the effects of ionizing radiation on living things

13

REM

The unit of dose equivalent or occupational exposure

14

Reproductive Failure

Cell that is unable to continue repeated divisions after being irradiated
