This document summarizes a presentation on ionizing radiation. It defines ionizing radiation as particles and electromagnetic radiation released by unstable atom decay. It lists the main types of ionizing radiation and some common uses of radiation like power generation, laboratories, and medicine. Finally, it discusses the units used to measure radiation exposure and effects, noting that different radiation types can be stopped by varying materials like paper, aluminum, concrete or lead depending on their penetrating ability.

2. IONISING RADIATION
Particles and electromagnetic radiation released by the
decay of unstable atoms.

3. IONISING RADIATION-
1. Alpha Particles
2. Beta Particles Radionuclides
3. Neutrons
4. Gamma Rays
5. X Rays Elecromagnetic Radiation

5. WHAT IS RADIATION USED FOR?
1. POWER GENERATION
2. LABORATORIES
3. RADIOACTIVE TRACERS
4. MEDICAL

6. UNITS-
ACTIVITY ( BECQUEREL)
1 Becquerel = 1 disintegration per second
ABSORBED DOSE (GRAY)
1 Gray(Qy) = Energy absorption of 1 joule/kg
DOSE EQUIVALENT (SIEVERT)
Equivalent dose(Sv) = Absorbed Dose(Gy) × Q
Q = it is a quality factor, dependent upon radiation type

7. EFFECTS
•ALPHA PARTICLES - Stopped by sheet of paper
or skin
•BETA PARTICLES - Stopped by few mm of
aluminium
•GAMMA RAYS - Stopped by several meters of
concrete or cms of lead
