2

Types of ionising radiation

Alpha

X-ray

3

What does ionising mean

Causes atoms to lose elections and become ions or charged atoms

4

X-rays are inversely proportional to distance from energy source TRUE/FALSE

TRUE

5

Further you move away - exposure is reduced by the same amount TRUE/FALSE

FALSE - its decreased by a SQUARE of the distance

Inverse square law

6

Define somatic mutation

Mutation occurring in cells which undergo division (not germ cells) LIVER, SKIN, BLOOD

7

Examples of germ cells

EGGs or SPERM

8

Exposure is calculated by

Exposure rate x Time

9

Define ALARA

As low as reasonable achievable

10

Define Photon
