Radiation Flashcards
What is Contamination
When radioactive particles get ON to other objects
What is irradiation
The process by which objects are exposed to radiation (can happen with radiation of any type)
What are the types of ionising radiation
Alpha
Beta
Gamma
X-rays
What determines how harmful radiation is
Type of radiation
Where you’re exposed to it
The amount that you receive
What radiation is non ionising
Radio waves
Microwaved
Infrared radiation
Visible light
Ultraviolet
What t
What types of radiation are the most dangerous and why
Ionising as they can enter living cells and interact with the molecules inside.
The radiation can ionise DNA which can cause mutations
How can exposure to radiation lead to cancer
The radiation ionise our DNA which can lead to random mutations
This could then lead to cells dividing uncontrollably and developing cancer
What other radiation can also cause cancer
Ultraviolet
What is the order of radiation from mist harmful to least harmful
Alpha
Beta
Gamma
X-rays
Ultraviolet
Visible light
Infrared
Microwave
Radiowaves
If the source is outside the body what the most dangerous sources
Beta and Gamma as alpha particles cannot penetrate the skin whereas they can
If the source is on/inside the body then what is the most dangerous source of radiation
Alpha as it would be able to make it into your cells
What affects the dosage of radiation
How far from the source you are
How long your exposed
How radioactive that substance is
How do you minimise irradiation and avoid contamination
Wear protective gear
Handling the radioactive item with tools
Storing item in a lead lined box when possible
