RADIATION
DOSSIER (Nonionizing,
Ionizing)
Name: Nonionizing
Radiation
Use: power transmission, communication,
illumination, heating, cooking, vision, photosynthesis
(sun light), etc.
Source: Ultraviolet light, visible
light, infrared radiation, microwaves, radio & TV,
power transmission
Recommended exposure: different depending
on source, i.e. sun light can damage skin
Absorption: depends on source
Sensitive individuals: variable, i.e.
fair skinned children (sunburn)
Toxicity/symptoms: Depends on source.
Solar radiation: sun burn, cataracts, cancer; microwave
radiation: warming of skin or internal organs, controversy
exists around exposure to low frequency energy such
as AC power lines.
Regulatory facts: government regulates
exposure
General facts: long history of use
Environmental: Our dependency on energy
results in a range of consequences for example drilling
for oil and mining coal to run power plants to generate
electricity, in turn mercury is released in the atmosphere
from burning coal
Recommendations: depending on individual
sensitivity; limit exposure to solar radiation (ultraviolet
radiation); reduce energy consumption
