Nuclear Proliferation

Two kinds of Materials -plutonium -enriched uranium -> 1st generation nuclear weapons soviets exploded their first bomb in 1949. Three days later the U.S. dropped another bomb on Nakasaki.

Book: Who will stop the bomb?- " To understand the desicon to use Atomic bombs, one must have a real sence of what World War ll was like for Americans."

Radiation & Its Causes: there are many types of radation: Electromagnetic radiation: (Energy in the form of electromagnetic waves or photons.) Non-ionizing

Thermal radiation (heat radiation) Radio waves

Microwave radiation, as used in microwave ovens

Infrared radiation (IR), produced by heat Visible light light that is visible to the naked eye

Ultraviolet radiation (UV) is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays. Ionizing

Gamma radiation, usually emitted by radioactive atoms

Particle radiation: (Energy in the form of moving subatomic particles.)

Alpha radiation, composed of the nuclei of helium-4 atoms

Beta radiation, consisting of energetic electrons or positrons

Neutron radiation, consisting of neutrons

The formula for the radiation reaction in a vacuum in SI units is

One of the risks is that you are exposed to small doses of radiation (radiopharmaceuticals). Radiation poisoning is always a concern when using this type of treatment. Radation also cures, and helps. Very intense radiation kills within days, or even hours hours, by destroying the central nervous system, which quickly leads to collaspe and death.Lower levels lead to sickness nausea, vomiting, denydration and death. Radiation is harmful in anyway.
