Flashcards in Rad Pro Chapter 3 Vocab Deck (22):
1

Bystander effects

The effect of radiation on cells that are adjacent to those directly affected by radiation

2

Deletion

A chromosomal effect that causes a loss of genetic material

3

Dicentric

A chromosome that has two centers or two centromere's

4

Division Delay

Slowdown of cell division due to irradiation

5

Dose-response Relationship Curve

A graphical representation of observed effects compared with radiation dose

6

Free Radical

An atom that has in an unpaired electron making a highly reactive. It is produced as a result of radiolysis in water

7

HeLa

Letters that represent the first two letters of the patients name and last name in an experiment conducted by Puck using urine cervix cells to produce cell cultures

8

Interphase Death

Cell death occurring before mitosis

9

Linear quadratic dose-response curve

Graphical representation of relationship between radiation does an observed response, in which any dose may have potential effect, and there is direct relationship between radiation dose and observed effect

10

Linear Energy Transfer (LET)

A measure of the rate at which energy is deposited from ionizing radiation to soft tissue

11

Mutation

In structural change or transformation of chromosome that can be transmitted to offspring

12

Nonthreshold

Any does received, regardless of size, that will produce a response

13

Oxygen Effect

Name given to cellular response to radiation when oxygen is present

14

Point Mutation

A mutation that occurs as a result of the change to a single DNA base pair, created by one nucleotide being exchanged for another

15

Radiolysis

Breakdown of water using radiation

16

Radiosensitivity

The mount of reaction or response of a cell to radiation

17

Relative Biologic Effectiveness (RBE)

A comparison of how effective types of radiation are compared with gamma and x-rays

18

Ring

Mutation of chromosome causing it to become ring-shaped

19

Sigmoid

S shape type of dose response relationship

20

System

A group of cells that perform a particular function

21

Threshold

The point where a stimulus starts to produce an effect

22

Translocation

Altering of a chromosome either by a portion of it transferring to another chromosome or to another section of the same chromosome
