Nuclear pollution refers to contamination by radioactive elements found in air, water, or land, primarily originating from nuclear fission, mining, and power plants. The document details the severe health risks associated with nuclear radiation, including the impact of significant accidents like Three Mile Island, Chernobyl, and Fukushima, which caused extensive environmental and human harm. It also discusses the lethality of radiation doses, emphasizing that exposure can lead to long-term health issues, including increased cancer rates.

2. What Is Nuclear Pollution
Nuclear pollution is the pollution that contains
radioactive elements. Nuclear Pollution may
be in the air, water or on land. Nuclear
Pollution can come from a variety of sources .
E.g.- Nuclear fission ,Radioactive mining,
Nuclear Fuel reactor materials, Nuclear power
plants etc.

3. Nuclear Power Plant
• It is used to generate electricity.
• It used nuclear elements as heat source in
plants which works on the nuclear fission.
• The energy we get from 1gm of pure Uranium
Is equal to energy received from the burning
Of 3500 tonnes of coal.

4. Effects of Nuclear pollution
Nuclear Radiation seriously effects
the life on Earth
 Explosion from the Nuclear
bombs does two type of
damage:-
I. Directly from blast
II. Dispersal of Radioactive
isotopes

6. Radiation Doses and Health
Determining the point at which the exposure
or dose becomes a hazard to health.
–5,000 mSv is considered lethal in 50% of
people
–1,000-2,000 mSv sufficient to cause health
problems
–50 msv maximum allowed dose for
workers in the industry (30 times aver.
natural background)

7. Nuclear Power Plant Accidents
US Nuclear Regulatory Commission
–Sets performance goal for a single
reactor at 0.01%
–If there were 1,500 plants a melt down
could be expected every seven years
–Unacceptable risk

8. Three Mile Island
Occurred March 28, 1979 near
Harrisburg, PA
–Malfunction of a valve resulted in
partial core meltdown
–Intense radiation released to interior of
containment structure
–Small amount of radiation released
into environment

10. Chernobyl
Occurred April 26, 1986
• Worst accident in history of nuclear power
generation
• Failure in cooling waters
– Reactor overheated melting the uranium fuel
– Explosions removed top of building
– Fires produced a cloud of radioactive particles

11. Chernobyl
30 km zone surrounding Chernobyl evacuated
– City of Prypyat, pop. 48,000 at time of accident,
now a ghost city.
– Thyroid cancer increased in Belarus, Ukraine and
the Russian Federation
– Trees and vegetation damaged
– Ultimately be responsible for 16,000 deaths

14. Fukushima
Occurred March 11,2011
•One of the three main worst Nuclear
power plant accidents.
•Failure of the Reactant coolant due to
Tsunami
•20 km zone around Fukushima
evacuated

17. Affects the human as well as Aquatic
life

18. Hiroshima And Nagasaki
Around 80,000 people were affected
• The effect is still there
