History – WWII the first ever.
1940’s Manhattan Project First Atomic bombs were dropped on
Hiroshima and Nagasaki Cities Flattened 40,000 – 75,000 died Died from explosion and from radiation
after the initial explosion

History – Chernobyl Incident 1986 reactor accident caused 10,000
to 15,000 deaths More exposure to radiation than
Hiroshima bombs Radiation is still there up to this day 4000 cases of Thyroid cancer

Other International Issues: Cold War North Korea creating Nuclear Weapons War on Iraq Terrorists could use nuclear weapons

Why we SHOULD be afraidScientists have carried out several
experiments researching how radioactivity, compares to regular
diseases, how natural uranium in drinking water affects us, and how it affects
cancer.
![Page 8: Why have people become increasingly paranoid and scared since the first atomic bomb dropped in 1945.](https://reader036.fdocuments.us/reader036/viewer/2022062600/5a4d1b747f8b9ab0599b6aec/html5/thumbnails/8.jpg)
Uranium in Drinking Water Studied an Aboriginal Community
where there are small doses of uranium in their drinking water
Found that the small doses of uranium intake through a 15 year period had little affect in increasing cancer likeliness (13 in 100,00)
BUT, the population studied is very small so isn’t very accurate
![Page 9: Why have people become increasingly paranoid and scared since the first atomic bomb dropped in 1945.](https://reader036.fdocuments.us/reader036/viewer/2022062600/5a4d1b747f8b9ab0599b6aec/html5/thumbnails/9.jpg)
Techa River Cohort Between 1950 and 1960 radioactive waste
was thrown into techa river which greatly affected those who lived on the banks that internally and externally contacted the radioactivity.
Found breast cancer rates increased greatly. This is also a problem of Nuclear Waste,
however later on we will learn that in present day reactors, nuclear waste isn’t an issue
![Page 10: Why have people become increasingly paranoid and scared since the first atomic bomb dropped in 1945.](https://reader036.fdocuments.us/reader036/viewer/2022062600/5a4d1b747f8b9ab0599b6aec/html5/thumbnails/10.jpg)
Highly Enriched Uranium HEU can be found in the ground around
the world Terrorists can easily access this material WWII atomic bombs had a very simple
mechanism which Terrorists can easily incorporate given they had the money
Although WWII Atomic bomb is weak and incomparable to present day Nuclear weapons, it can still flatten cities and cause great damage.

North Korea Only very recently did North Korea announce
a successful testing of an Atomic Bomb as powerful as the ones created in the Manhattan Project in WWII
North Korea broke U.N Security Council Rules U.S is demanding North Korea stop North Korea is only further isolating
themselves Yet at the same time posing a threat to
international security

On the flip side…A lot is being done to prevent further
incidents such as the Chernobyl Incident, and countries have signed on to treaties
and agreements
![Page 13: Why have people become increasingly paranoid and scared since the first atomic bomb dropped in 1945.](https://reader036.fdocuments.us/reader036/viewer/2022062600/5a4d1b747f8b9ab0599b6aec/html5/thumbnails/13.jpg)
What has been done? Treaties have been signed:1. Nuclear non-proliferation treaty2. Limited Test Ban Treaty U.N Security Council are trying to
maintain order Countries are keeping Nuclear
Reactors safe from Terrorists
![Page 14: Why have people become increasingly paranoid and scared since the first atomic bomb dropped in 1945.](https://reader036.fdocuments.us/reader036/viewer/2022062600/5a4d1b747f8b9ab0599b6aec/html5/thumbnails/14.jpg)
Nuclear Reactors Present day Nuclear Reactors have
guidelines Something like the Chernobyl Incident
will never happen again
![Page 15: Why have people become increasingly paranoid and scared since the first atomic bomb dropped in 1945.](https://reader036.fdocuments.us/reader036/viewer/2022062600/5a4d1b747f8b9ab0599b6aec/html5/thumbnails/15.jpg)
Nuclear Waste Nuclear Waste is take care of very
safely nowadays The waste is isolated and left to decay
naturally After 99.9% of the radioactivity has
decayed they take the waste and use it productively (electricity etc.)

Analysis of danger of Radioactivity
![Page 17: Why have people become increasingly paranoid and scared since the first atomic bomb dropped in 1945.](https://reader036.fdocuments.us/reader036/viewer/2022062600/5a4d1b747f8b9ab0599b6aec/html5/thumbnails/17.jpg)
Radioactivity and Cigs Scientists created realistic radioactive
situations and compared it to common diseases such as obesity, minor smoking and air pollution
Comparing particularly the survivors of the Chernobyl Incident
Found that such radioactive exposure is LESS harmful compared to previously mentioned common diseases.
![Page 18: Why have people become increasingly paranoid and scared since the first atomic bomb dropped in 1945.](https://reader036.fdocuments.us/reader036/viewer/2022062600/5a4d1b747f8b9ab0599b6aec/html5/thumbnails/18.jpg)
The U.S and Russia The U.S and Russia has recently
decided to THROW AWAY 68 tonnes of Weapon Grade Plutonium
They are doing this to encourage other nations
The WGP will be taken to create electricity
![Page 19: Why have people become increasingly paranoid and scared since the first atomic bomb dropped in 1945.](https://reader036.fdocuments.us/reader036/viewer/2022062600/5a4d1b747f8b9ab0599b6aec/html5/thumbnails/19.jpg)
Terrorists and HEU As previously mentioned it is not
difficult for terrorists to access HEU, but all nation’s military are protecting known sources and the U.S is encouraging them to hand the HEU over to be thrown away
Although it isn’t so difficult to create an atomic bomb
BUT Terrorists will need 2million USD to create one
![Page 20: Why have people become increasingly paranoid and scared since the first atomic bomb dropped in 1945.](https://reader036.fdocuments.us/reader036/viewer/2022062600/5a4d1b747f8b9ab0599b6aec/html5/thumbnails/20.jpg)
Should we be AS scared as many people already are?
You just watched my presentation, you decide
OH and…If a nuclear bomb was to be dropped on our heads, we’d die so fast we wouldn’t feel anything :P sadistic? Yeah I know.
