Key PointsNotes
Two types of
radiation 1.Background radiation: naturally found in earth
and outer space
2.Manmade radiation: electronic products
Groups of
radiation 1. Ionized radiation
2.Non-ionized radiation
Ionized radiation Can change atoms and strip away electrons
Break some chemical bonds (e.g alpha, beta
particles, gamma and x-ray)
Stochastic health effects:
Long term: low level exposuredifficult to detect
Increased exposure affects likely hood, but not type
or severity of effect
Cancer: uncontrolled growth of cells, which results
in damage at cellular and molecular level.
Changes in DNA: mutations: teratogenic =
malformation of embryo and gentics
Non-stochastic health effects—acute (severe or intense
degree):
Short-term with high level of exposure
Increase level of exposure = more severe effects
Cancer and radiation sickness
Non-ionized
radiation Microwave oven:
Form of electromagnetic radiation
Absorbed by food
Passes through glass, paper, plastic
Reflected by metal
Water molecules vibrate which creates heat
Not radioactive or contaminated
Cooks from outside
Human health and microwaves:
Animal research-genetic changes
Immune response
Lens of eye is sensitive
Can cause cataracts
Painful burn
Temporary sterility

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!
