What is Solar Radiation?
◊ heat energy from the sun.
◊ …including the infrared.visible, and ultraviolet
wavelengths.
◊ Also referred to as shortwave radiation.
◊ And is essential source of energy for the
worlds climate system
Why we need Solar Radiation
◊ The earth receives a
huge amount of energy
from the sun in the
form of solar radiation.
◊ If we converted to
usable energy just
0.2% of the solar
radiation that falls on
our nation, we would
meet the energy
demand of the entire
United States.
Causes of Solar Radiation
◊ In some anuran species, ambient levels of UV-B
cause mortality in embryonic stages and hatching
success is significantly reduced. Projected increases
in UV-B may affect an increasing number of species.
◊ The adverse effects of UV-B may eventually be
manifested at the population level and may ultimately
contribute to population declines.
Effects of Solar Radiation
◊ Since the late 1970s, the amount of solar radiation
the sun emits, during times of quiet sunspot
activity, has increased by nearly .05 percent per
decade.
◊ This trend is important because, if sustained over
many decades, it could cause significant climate
change.
◊ If a trend, comparable to the one found in this
study, persisted throughout the 20th century, it
would have provided a significant component of
the global warming
Kinds of solar radiation
◊ UV-C
◊ UV-B
Pros and Cons
Pros
Cons
◊ We can convert the
solar radiation into solar
power.
◊ May cause sun burn
◊ Causes mutation on
different species
◊ Can also cause cancer.
◊ That’s all the pros.
Ways to Prevent Solar Radiation.
◊ Stay in the shade.
◊ Apply suntan lotion.
◊ Stay indoor.
◊ Pray that the sun doesn’t kill you.
Death toll caused my solar radiation.
◊ 2300 die each year caused my solar
radiation.
◊ People with certain skin color have
either a greater or lower risk of
acquiring cancer.
◊ Another cancer, Melanoma, have killed
55,000 people.
