4.Characteristics of Radiation and Radioactivity
What are the characteristics of radiation and radioactivity?
What are the characteristics of radiation and radioactivity?
It's important to know about radiation and radioactivity in order to protect yourself. So Let's look at them together.
Characteristics of Radiation
Shielding
Radioactive material
Walls block radiation.
Concrete allows even less radiation through.
Separation (Distance)
The amount of radiation received

Radioactive material
2 times farther away
Does the radioactive material stay there forever?
The power of radioactive materials to emit radiation (radioactivity) has the property of decreasing over time.
The time it takes for that ability to halve is called the physical half-life.
Characteristics of Radioactivity
Does radioactive material ingested through food stay in the body?
Don't worry. It will be discharged out of your body.
This is called the biological half-life.
Here's the point!
Radiation can be blocked and exposure can be reduced by moving away from radioactive materials.
The ability of a radioactive material to emit radiation decreases with time. (half-life).
