Radiation

Question 1

The energy emitted and transferred through matter.

Answer 1

Radiation

Question 2

Occurs when an electromagnetic radiation passes close to an orbital electron of an atom and transfer sufficient energy to the electron to remove it from the atom.

Answer 2

IONIZATION

Question 3

The orbital electron and the atom which it was separated are called

Answer 3

Ion Pair

Question 4

Matter that intercepts radiation and absorbs part or all of it.

Answer 4

IRRADIATION

Question 5

Matter that has been irradiated and becomes a source of radiation.

Answer 5

CONTAMINATION

Question 6

TYPES OF RADIATION:

Answer 6

1. ACCORDING TO DIRECTION OF PROPAGATION
2. ACCORDING TO SOURCE
3. ACCORDING TO ABILITY TO IONIZE
4. ACCORDING TO THE PHYSICAL CHARACTERISTIC

Question 7

1. RADIATION ACCORDING TO DIRECTION OF PROPAGATION EXAMPLE

Answer 7

Longitudinal - The movement of particles are parallel to the direction of the wave

Transverse-
The movement of particles are perpendicular to the direction of the wave

Question 8

2. RADIATION ACCORDING TO SOURCE
   EXAMPLE

Answer 8

Natural Environmental Radiation- Also known as background radiation

Artificial Radiation - Also known as Man-made Radiation

Question 9

3. RADIATION ACCORDING TO ABILITY TO IONIZE

Answer 9

Non-ionizing radiation - Radiation for which the mechanism of action in tissue does not directly ionize atomic or molecular systems through a single interaction.

Ionizing radiation- Radiation that is capable of ionization.

Question 10

4. RADIATION ACCORDING TO THE PHYSICAL CHARACTERISTIC

Answer 10

Particulate Radiation
Electromagnetic Radiation
