Flashcards in Rad Pro Chapter 5 Vocab Deck (33):
1

Absolute risk model

(1) estimates a continual increase in risk, independent of the age-specific cancer risk at time of exposure. Also known as the additive risk model.

2

Acute

Rapid, severe

3

Ankylosing spondylitis

Immobility of the vertebrae

4

BEIR

Committee on the Biological Effects of Ionizing Radiation

5

Benign

Non-progressive

6

Carcinogenic

Cancer-causing

7

Carcinoma

A growth or tumor

8

Chronic

Slow, progressive

9

Doubling dose

The dose of radiation required per generation to double the spontaneous mutation rate

10

Excess risk

The number of excess case of cancer observed compared with expected spontaneous occurrence

11

Fibrosis

Abnormal formation of fibrous tissue

12

Follicular

Sac or cavity like

13

Genetically significant dose (GSD)

An average calculated from the gonadal dose received by the entire population in use to determine the genetic influence of low dose to the whole population

14

Hypoxic

Low levels of oxygen

15

Leukemia

Cancer of the blood forming cells in bone marrow

16

Loci

Spot, place of origin

Papillary

Nipple like, protruding

25

Parenchymal

Essential life-sustaining cells

26

Progeny

Offspring

27

Radiation hormesis

The controversial hyoothesis that chronic low doses of ionizing radiation stimulates repair mechanism that protect against disease

28

Radiocarcinogenesis

Radiation producing cancer

29

Radium

Radiogenic substance

30

Radon

Radiogenic gas

31

Relative risk model

(1) relates age at the time of radiation exposure to cancer risk estimate. Also known as the multiplicative risk model.

32

Stochastic

Occurring randomly in nature

33

Zygote

Fertilized egg
